    H AMILTON, Circuit Judge. In this case we revisit factual
    and legal issues concerning the Illinois law establishing

    fire protection districts and one district’s effort to shut
    down the private market in fire alarm monitoring
    services by substituting for it a less safe and less
    reliable system operated by just one chosen vendor.
    In 2009 the Lisle-Woodridge Fire Protection District
    passed an ordinance under which it took over fire
    alarm monitoring for all commercial properties in the
    District. The private alarm companies that had previously
    provided those services in the District sued, alleging
    that the ordinance interfered with their business,
    created an illegal monopoly for the District, violated
    their constitutional rights, and exceeded the District’s
    statutory powers. In an earlier appeal from the district
    court’s first order permanently enjoining the District
    from implementing the ordinance and granting sum-
    mary judgment for the alarm companies, we affirmed
    in part, reversed in part, and remanded, finding on
    review of summary judgment that the District had the
    authority to enforce parts of the 2009 ordinance. We
    remanded for the district court to revise its permanent
    injunction. ADT Security Svcs., Inc. v. Lisle-Woodridge Fire
    Protection District, 
    672 F.3d 492
     (7th Cir. 2012).
    On remand the district court held a four-day evidentiary
    hearing. The district court issued a modified permanent
    injunction that was based on new factual findings that
    are more detailed and differ somewhat from the limited
    summary judgment record upon which we based our
    2012 decision. The District now appeals from the
    revised permanent injunction order with a long list of
    objections, but it argues primarily that the revised perma-
    nent injunction conflicts with our 2012 decision.
    Nos. 12-2925 and 12-2981                                    3
    In our 2012 decision, we preserved much of the
    District’s authority to enforce its ordinance. But the
    evidentiary hearing following our remand showed that
    many material facts are actually different from what
    we had to assume when we reviewed the grant of sum-
    mary judgment, particularly with regard to the statutory
    authority for and the motivation and efficacy of the Dis-
    trict’s plan. We therefore find, with a few minor excep-
    tions, that the modified permanent injunction was a
    sound exercise of the district court’s discretion. We
    affirm the injunction with a few modifications.
    I. Factual and Procedural Background
    A. The Parties and Alarm Signaling and Monitoring
    Appellant Lisle-Woodridge Fire Protection District
    (“the District”) is a specific type of municipal entity
    established by the Illinois Fire Protection District Act (“the
    Act”), 70 Ill. Comp. Stat. 705/1 et seq. The District pro-
    vides fire protection services to residents in the villages
    of Lisle and Woodridge, Illinois, and other unincorporated
    parts of DuPage County. Under the Act, the District has
    the power to set fire codes and to establish standards
    for fire alarm and dispatching services. 70 Ill. Comp. Stat.
    705/6(i), 705/11. The District funds its work through
    taxes and is governed by a board of trustees. See 705/14.
    The District does not receive fire alarms directly. Rather,
    fire alarms within the District are received and dis-
    patched by intervening appellant DuPage Public Safety
    Communications, also known as “Du-Comm.” Du-Comm
    4                                Nos. 12-2925 and 12-2981
    is an inter-governmental entity made up of 28 member
    police and fire agencies in DuPage County, including
    the District. Du-Comm provides emergency dispatch
    services to those member agencies.
    The plaintiff-appellees are private alarm companies
    that provide alarm and monitoring services to com-
    mercial properties in the District. For example, a ware-
    house, office building, or apartment complex may
    contract with an alarm company to install and monitor a
    building-wide alarm system. That system receives a fire
    alarm signal at the building’s main alarm board from
    a smoke detector in the building and then transmits
    that signal to the local dispatcher to send emergency
    services. The alarm companies also provide monitoring
    services: in addition to fire alarm signals, the
    alarm boards also send “trouble” and “supervisory”
    signals, which indicate to the alarm companies either
    that the alarm board is not functioning or that someone
    at the premises has interfered with the system (e.g., shut
    off a water valve supplying the sprinkler system).
    The alarm companies receive the signals at “Central
    Stations,” which need not be geographically close to the
    customer’s premises. Often an alarm company will have
    one company-wide Central Station that it uses to
    receive and send dispatch signals for all of its customers.
    Prior to this litigation, the plaintiff alarm companies
    provided alarm and monitoring services to their cus-
    tomers as follows: smoke and fire detectors in a building
    would send a signal to the alarm panel in the building,
    the alarm panel’s communication device would send a
    Nos. 12-2925 and 12-2981                                   5
    signal to the alarm company’s Central Station, and an
    operator at the Central Station would make a telephone
    call to Du-Comm for dispatching. An alternative to this
    “Central Station” model for fire alarm systems is the
    “Remote Supervising Station” model in which fire alarm
    and monitoring signals are transmitted from buildings
    to a facility other than a Central Station, such as a munici-
    pal dispatch board.
    B. The 2009 Ordinance
    In September 2009, the District passed an ordinance
    that attempted to overhaul alarm signaling and
    monitoring in the District. The ordinance required all
    commercial property owners to terminate their contracts
    with private alarm companies and instead to adopt and
    pay for an alarm and monitoring system provided by
    the District. Under the new system, alarm boards at
    commercial properties would be equipped with wireless
    transmitters owned by the District that would transmit
    alarm, trouble, and supervisory signals to a receiving
    unit located at the District’s Fire Station 3. The receiving
    unit at Station 3 would automatically transmit the
    signals to another receiving unit at Du-Comm, which
    would then dispatch the relevant emergency response.
    The District claimed that it switched to this system,
    which the District deemed a Remote Supervising Station
    system, because it was experiencing outages and other
    problems with the plaintiffs’ private monitoring through
    Central Stations, including that alarm notifications were
    6                                  Nos. 12-2925 and 12-2981
    delayed and trouble signals indicating outages did not
    trigger prompt responses. DC-360 at 3; Freeman 265.1
    District officials claimed that the new system would
    provide two main advantages over the signaling and
    monitoring provided by the private alarm companies:
    (1) it was entirely wireless and automated, eliminating
    the need for a human-operated telephone call from a
    Central Station to Du-Comm and decreasing the time it
    took to respond to alarms, and (2) it connected all
    signals directly to the District’s own board, allowing
    the District to monitor all signals and to ensure that
    all outages were addressed.
    The District took bids from several companies to set
    up the system and provide the wireless transmitters. It
    settled on a company called Chicago Metropolitan Fire
    Prevention Company — also a defendant and appellant
    here. Chicago Metro would supply the transmission
    equipment: AES/Keltron-manufactured wireless radio
    transmitters for all the properties, the District’s receiving
    unit at Station 3, and the second receiving unit at Du-
    Comm. (AES and Keltron radios are synonymous.
    Coveny 367.) The District sent a notice to all commercial
    property owners in the District, informing them that

    hearing held May 24-29, 2012 are noted “[Witness name] [page

    Nos. 12-2925 and 12-2981                                  7
    the new ordinance had been adopted and that they
    would now be charged $66 per month for the alarm
    and monitoring services and for the radio transmitter
    and its maintenance. The notice also boldly informed
    subscribers: “If you are under contract for monitoring
    with another vendor, our ordinance now supersedes
    those contracts and makes them null and void.”
    C. Proceedings Before the District Court
    The alarm companies quickly filed suit in the Northern
    District of Illinois, alleging that the ordinance violated
    federal antitrust laws and federal constitutional
    guarantees of equal protection, due process, and the
    right to contract, and that the District did not have the
    legal authority to enact the ordinance under the Illinois
    Fire Protection District Act. On July 20, 2011, the District
    Court granted the alarm companies’ motion for partial
    summary judgment, and on August 16, 2011 entered a
    permanent injunction enjoining the District from
    enforcing and implementing the Ordinance. The
    District and Chicago Metro appealed both the summary
    judgment order and the permanent injunction.
    D. This Court’s 2012 Opinion
    On February 27, 2012, we issued an opinion (“ADT I”),
    reversing in part and remanding for further proceedings.
    See 
    672 F.3d 492
     (7th Cir. 2012). We held that the District
    was authorized under the Act to require buildings to be
    8                                  Nos. 12-2925 and 12-2981
    connected directly to its dispatching center and to
    require that the transmission network be wireless, but
    we found that the District was not authorized under
    the Act to be the sole provider of the necessary equip-
    ment. In essence, we found that the District had fairly
    broad authority in its capacity as a fire safety regulator
    but little if any authority to step in as a participant (or
    the sole participant) in the competitive market for com-
    mercial fire alarm signaling and monitoring services.
    Looking first to the District’s authority under the Act,
    we held that the Act permitted the District to require
    property transmitters to connect directly to the District’s
    own receiving board and to require that the transmission
    system be wireless. Section 11 of the Act permits fire
    protection districts to “adopt and enforce fire preven-
    tion codes and standards parallel to national standards.”
    70 Ill. Comp. Stat. 705/11. We interpreted “parallel” to
    mean that the District could choose to require one ac-
    ceptable option where national standards contemplated
    several acceptable options. ADT I, 672 F.3d at 501.
    In the fire protection world, national standards
    include the National Fire Protection Association’s
    “NFPA 72: National Fire Alarm and Signaling Code” (the
    “Code”). The Code contemplates the use of either a
    Remote Supervising Station system or a Central Station
    system. See NFPA 72 § 8.2, 8.4 (2002).2 Given these options,
    2
    In our 2012 decision we used the 2010 version of the Code,
    but as we will explain below, the 2002 version is the relevant
    (continued...)
    Nos. 12-2925 and 12-2981                                   9
    we applied our interpretation of “parallel” to mean that
    it was within the scope of the District’s authority under
    the Act to require the use of a Remote Supervising
    Station system to the exclusion of Central Stations. The
    Code permitted the use of either Central Stations or a
    Remote Supervising Station, and the District’s system was
    a Remote Supervising System. We applied the same
    interpretation of section 11 to the District’s wireless
    requirement and found that it too was “parallel” to the
    NFPA Code, which lists wireless radios as one
    acceptable method of transmitting signals. See ADT I, 672
    F.3d at 502, citing NFPA 72 § 26.6.2.4.1 (2010); see also
    NFPA 72 § 8.5.2.4.1 (2002).
    We affirmed the district court’s grant of summary
    judgment to the extent it held that the District could not
    anoint itself or its chosen vendor as the exclusive
    provider of the wireless radio transmitters. We found
    that the Code did not authorize districts to do so and
    instead made property owners responsible for the equip-
    ment at their property. ADT I, 672 F.3d at 503 (“The
    District, by making itself the sole purveyor, installer,
    inspector, tester, and maintainer of the necessary radio
    transmitter equipment, has usurped responsibilities
    the NFPA code accords to property owners.”).
    We remanded to the district court for further proceed-
    ings in light of these holdings and to address the issues

    edition. The sections we relied on in ADT I are substantially
    similar in the 2002 edition.
    10                                  Nos. 12-2925 and 12-2981
    remaining before the district court. We did not reach
    all remaining issues, but we addressed several issues to
    guide the district court in future proceedings. We noted
    that the District would not likely have an “effective
    monopoly” on monitoring and equipment if wireless
    transmitters other than the District’s Keltron units
    would be compatible with the system, which it seemed
    to us was likely. We also noted that we interpreted the
    Act as not permitting the District to charge service fees
    to its residents beyond the taxes it is authorized to collect.
    E. Proceedings on Remand
    Upon remand, the district court held an evidentiary
    hearing to resolve factual disputes relevant to modifying
    the permanent injunction in light of our opinion. The
    court heard four days of testimony. Plaintiffs’ witnesses
    included Louis Fiore, a consultant on alarm monitoring
    and a special expert to the NFPA, and Edward Bonifas,
    vice president of plaintiff Alarm Detection Systems.
    Defendants’ witnesses included Thomas Freeman, Chief
    of the District, James French, the District’s Bureau Chief
    for Fire Prevention, Lawrence Coveny of Chicago
    Metro, and Brian Tegtmeyer, the executive director of Du-
    Comm. Only Fiore was found to be an expert witness. See
    Tr. 53, 138-39 (district court permitted Fiore to testify as
    expert witness; plaintiffs’ counsel withdrew Bonifas as
    opinion witness).3
    3
    Appellants argue that the district court abused its discretion
    in treating Fiore as an expert because the alarm companies
    (continued...)
    Nos. 12-2925 and 12-2981                                       11
    After the hearing the district court ordered the parties
    to submit proposed findings of fact and proposals for
    a modified permanent injunction. On July 6, 2012 — seven
    days before the District’s submissions were due — the
    District passed a new ordinance. DC-360 at 2; Joint Sepa-
    rate App. 66-75. The new ordinance repealed the 2009
    ordinance and replaced it with a modified set of require-
    ments. Under the new 2012 ordinance, the District would
    not own any transmitters and would permit property
    owners to contract with private companies for alarm
    transmission and monitoring and the necessary equip-
    ment. But the signals would still need to be transmitted via
    the District’s wireless network to the District’s receiver
    at Station 3 to be transmitted to the receiver at Du-Comm.
    Under this arrangement, the District would collect no
    fees from property owners but Du-Comm would
    (...continued)
    did not provide an expert report prior to the hearing. See Fed.
    R. Civ. P. 26(a)(2)(B). But appellants had received Fiore’s
    affidavit over a month before the hearing, and it covered
    substantially the same ground as his direct testimony. See DC-
    287, Ex. 1. The purposes of Rule 26(a)(2) were satisfied because
    the appellants had ample time to prepare for Fiore’s testimony
    at the hearing and there was no showing of unfair surprise.
    To the extent that there were any discrepancies between his
    testimony and his affidavit, such differences were harmless.
    See Banister v. Burton, 
    636 F.3d 828
    , 833 (7th Cir. 2011) (failure
    to file 26(a)(2)(B) report was harmless where opposing party
    was not surprised by the content of the testimony). The
    district court did not abuse its discretion in allowing Fiore
    to testify as an expert witness.
    12                                 Nos. 12-2925 and 12-2981
    collect fees on its behalf. The District argued before the
    district court that the new ordinance mooted the con-
    troversy; the plaintiff alarm companies disagreed.
    F. Modified Permanent Injunction
    On August 7, 2012, the District Court entered a
    Modified Permanent Injunction Order and issued ac-
    companying factual findings and conclusions of law.
    The court adopted the alarm companies’ findings of
    fact, conclusions of law, and proposed injunction provi-
    sions. In essence, the Modified Permanent Injunction 4
    required the District to permit the alarm companies
    to receive and transmit signals directly from property
    alarm boards (independently of the District) and to re-
    transmit those signals to Du-Comm via Central Stations.
    Specifically, the injunction barred the District from:
    requiring that any fire signals be sent to Station 3
    (instead it required that Station 3 be shut down), charging
    residents for fire protection services (including any fees
    charged by Du-Comm), selling or leasing fire alarm system
    equipment, and prohibiting signals from properties from
    being sent to Central Stations. The injunction required
    the District: to allow alarm companies to use any technol-
    ogy equivalent to wireless transmission and compliant
    with the NFPA code, to adopt the most current version
    of the NFPA code, to refund to property owners fees
    4
    We refer to the Modified Permanent Injunction simply as
    the “injunction,” because it is the injunction we are reviewing
    in this opinion.
    Nos. 12-2925 and 12-2981                                        13
    collected by the District since the 2009 ordinance took
    effect, to direct Du-Comm to cooperate with the
    alarm companies so it could receive wireless signals
    directly from Central Stations, and to direct Du-Comm
    to pre-populate its computer database with names and
    addresses of the private alarm companies’ customers
    to decrease response times.
    The injunction also prohibited the District from
    enforcing the new ordinance and redacted the 2009 ordi-
    nance in accordance with its provisions. The district
    court explained that, although many of the new
    provisions of the injunction seem to conflict with ADT I,
    that was because many of the factual assumptions that
    we had to make in ADT I turned out to be unsupported
    by the evidence presented at the hearing. The district
    court issued a separate memorandum explaining why
    the new ordinance did not moot the controversy.
    The District and Chicago Metro appealed. 5 They each
    point to many supposed flaws in the injunction and the
    accompanying findings of fact and conclusions of law.
    Most of their arguments do not persuade us. Rather, we
    agree with the district court that the new ordinance did
    5
    The District also sought a stay of the injunction from this
    Court, which we denied in part but granted to the extent that
    the injunction required the District to refund the fees it
    collected from resident subscribers. ADT Securities, Inc. v. Lisle-
    Woodridge Fire Protection District, Order, No. 12-2925; 12-2981
    (7th Cir. Sept. 11, 2012) (dismissing Nos. 12-2219 and 12-2220
    as moot).
    14                              Nos. 12-2925 and 12-2981
    not effectively moot this controversy. We also find no
    clear error in the district court’s factual findings.
    Instead, the facts found by the district court after the
    evidentiary hearing persuade us that, while the legal
    principles of ADT I still stand, given the actual facts
    here, the new injunction sets appropriate boundaries
    for the District and does not contravene ADT I in most of
    the ways that the appellants argue. However, we
    find that several parts of the injunction exceed the
    proper scope of injunctions. We modify the injunction
    by striking the portions requiring the District to refund
    fees to subscribers and requiring the District to adopt
    the most current versions of the NFPA code. We thus
    affirm the injunction with a few modifications.
    II.   Discussion
    The numerous arguments raised by the District and
    Chicago Metro on appeal fall into several categories.
    They argue that the injunction: (1) contravenes ADT I by
    barring the District from enforcing its direct-connect
    requirement, (2) exceeds the proper scope of injunctions
    by binding a non-party (Du-Comm) and awarding relief
    to non-parties (refunds to subscribers), and (3) ignores
    the 2012 ordinance that supposedly mooted the contro-
    versy or at least should have replaced the 2009 ordinance
    in the district court’s analysis.
    We have jurisdiction under 
    28 U.S.C. § 1292
     to review
    an appeal from an injunction. (Several claims remain
    pending before the district court, so there has been no
    Nos. 12-2925 and 12-2981                                15
    final judgment.) We review the district court’s factual
    findings for clear error, its entry of the injunction for
    abuse of discretion, and its legal conclusions de novo. See
    Knapp v. Northwestern Univ., 
    101 F.3d 473
    , 478 (7th
    Cir. 1996).
    Based on the facts revealed at the evidentiary hearing,
    we find that the injunction is generally appropriate
    and not an abuse of discretion. When we first heard this
    case in ADT I, we reviewed the district court’s grant
    of summary judgment. We were required to view the
    evidence and disputed facts in a light most favorable to
    the District and Chicago Metro. But the evidentiary
    hearing revealed many material facts to be quite
    different in reality from the inferences we were
    required to draw in the District’s favor in ADT I,
    including such critical issues as the District’s motive in
    enacting the ordinance, the efficacy of the new system,
    and the District’s authority to implement the new sys-
    tem. The District and Chicago Metro object to
    many of these findings on appeal, but we reject
    those arguments.
    Based on these findings, we find that the major elements
    of the injunction — shutting down the District’s Station 3
    and permitting private Central Stations to receive and
    transmit alarm signals — were well within the district
    court’s discretion. Commercial properties in the District
    must have some form of fire alarm monitoring, but the
    District’s plans and requirements for such services
    are beyond the District’s legal authority, so it was appro-
    priate for the district court to require the District to
    16                               Nos. 12-2925 and 12-2981
    permit private alarm companies to provide that essential
    service. Moreover, the facts have revealed that the Dis-
    trict’s system is less reliable and more dangerous than
    the private alarm companies’ systems, does not comply
    with NFPA standards, and interferes with the plaintiffs’
    ability to serve their customers.
    The 2012 ordinance did not remedy these ills so as
    to render this dispute moot. It would have the effect of
    continuing to block the alarm companies from
    providing alarm monitoring services to customers in
    the District. To the extent the injunction includes Du-
    Comm even though it is not a party, we find that
    the injunctive measures involving Du-Comm are appro-
    priate because Du-Comm expressed its willingness
    to cooperate in the ways required by the injunction. If Du-
    Comm does not follow through, the district court may
    need to determine Du-Comm’s exact status with respect
    to the injunction, including whether it might be
    deemed an agent of the District and already subject to
    contempt powers, but we hope that will not be necessary.
    Despite our approval of the core elements of the modified
    injunction, we take issue with a few of its ancillary ele-
    ments.
    A. Mootness
    We first address the threshold question of whether
    the 2012 ordinance mooted this dispute. See Pakovich v.
    Verizon LTD Plan, 
    653 F.3d 488
    , 492 (7th Cir. 2011). The
    District argues that its eleventh-hour repeal of the 2009
    ordinance and replacement of it with the new ordinance
    Nos. 12-2925 and 12-2981                                      17
    mooted the entire controversy. The District argues
    both that the new ordinance rendered the modified
    permanent injunction moot and that, at a minimum, the
    district court erred by not analyzing the new ordinance
    instead of the 2009 ordinance. We find that the 2012
    ordinance does not moot the dispute over the
    modified permanent injunction. The alarm companies
    would still face a variety of injuries stemming from
    the new ordinance.
    The problem of mootness posed by a defendant’s change
    in policy or practice poses a recurring problem when
    injunctive relief is sought. “[T]he mere cessation of the
    conduct sought to be enjoined does not moot a suit to
    enjoin the conduct, lest dismissal of the suit leave the
    defendant free to resume the conduct the next day.”

    445 F.3d 940
    ,
    947 (7th Cir. 2006), citing Friends of the Earth, Inc. v. Laidlaw
    Environmental Services (TOC), Inc., 
    528 U.S. 167
    , 189 (2000).
    But a case may still be moot if there is no reasonable
    expectation that the wrong will be repeated. Chicago

    445 F.3d at 947-49
     (finding it “highly
    unlikely” that city would continue to deprive contractor
    of fair hearing, but case was not moot with regard to
    damages award).
    Specifically, “[t]he complete repeal of a challenged law
    renders a case moot, unless there is evidence creating a
    reasonable expectation that the City will reenact the
    ordinance or one substantially similar.” Fed’n of Adver.
    Indus. Representatives, Inc. v. City of Chicago, 
    326 F.3d 924
    ,
    930 (7th Cir. 2003). We apply a rebuttable presumption
    18                                  Nos. 12-2925 and 12-2981
    that government actors will not repeat objectionable
    behavior after an injunction is lifted. 
    Id.,
     citing City of
    Mequite v. Aladdin’s Castle, Inc., 
    455 U.S. 283
    , 289 (1982)
    (case not moot where possibility remained that city
    would reenact previously enjoined ordinance language).
    This presumption can be rebutted if a local government
    reenacts provisions substantially similar to those
    initially repealed. See 13C Charles Alan Wright & Arthur
    R. Miller, et al., Fed. Prac. & Proc. § 3533.6 (3d ed.) (“repeal
    followed by reenactment of provisions similar to those
    repealed does not moot a continuing challenge”), citing
    Fireman’s Fund Ins. Co. v. City of Lodi, 
    302 F.3d 928
    , 936 n.8
    (9th Cir. 2002) (new ordinance and repeal of challenged
    ordinance while appeals were pending did not moot
    appeals where “core disputes between the parties
    remain[ed]”).
    Here, the new 2012 ordinance did not resolve the dis-
    putes between the parties. Under the new ordinance,
    alarm companies are permitted to receive alarm and
    monitoring signals at Central Stations, but they must
    transmit those signals to Station 3 via the District’s
    wireless network so that the signals would then be sent
    from Station 3 to Du-Comm for dispatching. The District
    claims that the new ordinance removes the District
    itself from the monitoring business and permits the
    alarm companies to provide those services to customers
    in the District. But the new ordinance keeps several
    requirements from the original ordinance that would
    continue to injure the alarm companies by effectively
    blocking them from monitoring in the District or that
    are beyond the District’s authority to impose.
    Nos. 12-2925 and 12-2981                                19
    The first and most obvious is that the new ordinance
    keeps Station 3 as a central part of the District’s
    monitoring plan. Under the new ordinance, according to
    the District, signals would be sent by Central Stations to
    Station 3 and then transmitted to Du-Comm. As we
    explain below, Station 3 does not meet the basic safety
    requirements to function as an intermediary station
    under the Code. The arrangement under the new
    ordinance would place even more of the fire alarm sys-
    tem’s essential connections at the unsupervised Station 3
    without back-up equipment than the original ordinance
    would have. This new requirement is not “parallel” to
    the Code and therefore is not within the District’s
    authority to require under the Act. See 70 Ill. Comp.
    Stat. 705/11.
    Second, to provide alarm monitoring and signaling,
    the alarm companies must join the District’s wireless
    network. This network is accessible with only one
    specific type of transmitter, which is not the type the
    alarm companies use. See Coveny 376, 439. Although
    the alarm companies proposed using several other types
    of radios in an attempt to work with the District’s
    wireless requirement, none are compatible with the
    type of network and receiver used at Station 3. 
    Id.
     at 383-
    385. In fact, the new ordinance specifically states that
    alarm companies will have to transmit all their signals
    to a “Keltron 703 Communications Board” to gain access
    to the District’s system. This requirement means that
    alarm companies must either replace all of their existing
    equipment and transmission technology or they cannot
    provide alarm monitoring services to customers in the
    20                               Nos. 12-2925 and 12-2981
    District. See Coveny 439. Excluding alarm companies
    from the monitoring business or making it unduly burden-
    some for them to participate raises significant concerns
    about the anti-competitive effects of this requirement, and
    the new ordinance perpetuates rather than solves
    this problem.
    Third, although the new ordinance technically permits
    the alarm companies to receive alarm signals at Central
    Stations, it requires the alarm and monitoring signals
    also to be sent simultaneously to the District’s Station 3.
    Besides the fact that Station 3 does not comply with the
    Code, this requirement is problematic because current
    alarm transmitters for commercial properties generally
    are incapable of sending two signals simultaneously
    (i.e., one to the Central Station and one to Station 3).
    Bonifas 180-81. Plaintiffs’ witness Bonifas stated that
    such dual monitoring is “absolutely not” feasible, because
    in the District “there is an installed population of alarm
    panels already in place,” a few of which may have the
    capability of adding equipment to allow two outputs,
    but the “vast majority will not.” 
    Id.
     He also explained
    that, when the District said that dual monitoring was
    possible, it used the example of Wal-Mart, which is a
    proprietary system and “has control of the alarm equip-
    ment that they buy,” and “can choose a product that
    automatically has two outputs and hang two transmit-
    ters on it and make it work.” Bonifas 180.
    Without dual monitoring, alarm companies are effec-
    tively precluded from monitoring their equipment
    at protected properties because existing transmitters
    Nos. 12-2925 and 12-2981                               21
    will be able to send only one signal and the new
    ordinance requires that a signal be sent to Station 3. The
    District’s solution for this under the new ordinance is
    that the alarm companies would receive trouble and
    supervisory signal notifications in batch emails from the
    District. But this would not allow the companies to re-
    spond properly to these signals. Bonifas described his
    company’s procedures for servicing broken equipment
    in response to trouble signals, and he explained that an
    email-based system is not compatible with this because
    emails will not populate the service logs for technicians
    in the field. Bonifas 155-56; see also id. at 215-16
    (“Email would not put the history into the computer
    where we operate our entire 30,000 account base to our
    service technicians and dispatch them and let them see
    what has happened with the system.”); id. at 184
    (“We wouldn’t be able to populate our service log
    and make sure that people get out and restore it, as well
    as the little tablet in the technician’s hands.”). Like
    the wireless network requirement, this requirement
    would effectively preclude the alarm companies from
    providing monitoring services and raises serious con-
    cerns about the anti-competitive effects of the new ordi-
    nance.
    Thus, there is a reasonable expectation both that the
    alarm companies’ complaints will not be satisfied by
    the new ordinance and that the new ordinance still
    exceeds the scope of the District’s legal authority. The
    2012 ordinance did not moot the dispute.

    B. Factual Findings
    In ADT I, we reviewed a grant of summary judgment,
    so the District benefitted from factual inferences in
    its favor and an under-developed record, particularly
    with regard to how the District’s plan would address
    its concerns about the safety and efficacy of alarm moni-
    toring in the District. See 672 F.3d at 496. But the
    facts found at the evidentiary hearing cast the District’s
    actions in a very different light. Specifically, we have
    since learned that under the District’s monitoring,
    building alarm boards were out of service at a higher
    rate than under the alarm companies’ monitoring. Al-
    though the District’s signals were responded to in a
    shorter time than those sent from Central Stations, that
    advantage easily could be achieved for signals sent
    from Central Stations too. And the District’s wireless
    network operated on a frequency less reliable than
    typical fire alarm network frequencies.6 The district court
    6
    Other evidence that has come to our attention since ADT I
    suggests that the District may have been motivated to adopt the
    ordinance not only for the purported safety improvements,
    but also for financial gain. A PowerPoint presentation to the
    District’s Board proposing the ordinance noted the “revenue
    stream” as an advantage of a “District-Owned Network,” and
    emails from Keltron to a Municipal Alarm Board Forum
    encouraged the District to adopt its own network because
    “without the revenue being collected specifically from alarm
    subscribers for receiving alarm service, municipalities will
    be laying off dispatchers firemen inspectors and other people
    (continued...)
    Nos. 12-2925 and 12-2981                                   23
    did not clearly err in adopting factual findings based
    on these revelations. See MPI Factual Findings ¶¶ 53, 59-
    60, 74-76.
    1. System Reliability
    Before the District took over all alarm monitoring
    with the ordinance, the alarm companies received moni-
    toring signals through Central Stations and would send
    a technician out to assess and repair the alarm equip-
    ment. Edward Bonifas, an executive of one of the
    plaintiff alarm companies, described how his company
    would respond to these signals: “Under trouble signal we
    would first notify the client to let them know that the
    system is in trouble. If they are under a service contract,
    we would dispatch a service person to the building to
    determine what the trouble is, make a repair to it and put
    the system back to normal again.” Bonifas 155. He ex-
    plained that “our service technicians, when they get to
    the field, can review the history of the account right on
    their PC or tablet while they are standing in the custom-
    ers’ building, so they have full information for how the
    system has operated.” Bonifas 184. Bonifas testified that
    with these procedures, “the average percentage of unre-
    stored signals and out-of-service accounts for fire alarm
    6
    (...continued)
    [sic].” See DC-303, Ex. I at 36; Ex. M at 70. The email blames
    the “central station industry” for these problems, claiming
    that it “is on a mission to take away all municipal monitoring
    and keep the revenue for themselves.” DC-303, Ex. M at 70.
    24                                Nos. 12-2925 and 12-2981
    accounts in the District is at or under two percent,” accord-
    ing to reports the company generates. Bonifas 161.
    Testimony at the hearing revealed much higher out-of-
    service rates with the District’s monitoring. Bonifas
    testified that he analyzed hundreds of pages of unrestored
    signals and out-of-service reports from Du-Comm.
    He found that once the District’s system became opera-
    tional, over 12 percent of accounts were out of service
    at any point in time. Bonifas 185, 195. Under the
    District’s system the District receives reports of outages
    and trouble and supervisory signals from Du-Comm.
    Records indicated that those reports had not been
    checked or reviewed at all. Bonifas 204. The District’s
    witnesses disputed this number, claiming that the
    percent of outages was under 2 percent, Freeman 302-03,
    but after hearing testimony from both sides, the district
    court credited the testimony of the alarm companies in
    its factual findings. MPI Factual Findings ¶ 53. That
    finding was not clear error.
    2. Response Times
    One of the District’s stated aims in passing the 2009
    ordinance was to shorten the response times — the time
    from when “a detection system noticed a smoke or fire
    condition to the time [the District was] notified” or dis-
    patch services were sent. See Freeman 265. According to
    Du-Comm, it could receive and dispatch alarms from
    private Central Stations in less than 60 seconds, but
    from Station 3 under the District’s system in less than
    30 seconds. Tegtmeyer 466-67. The reason for this dif-
    Nos. 12-2925 and 12-2981                                      25
    ference was that all of the addresses and other necessary
    dispatch information for the District’s subscribers
    were “pre-populated” into Du-Comm’s computers. The
    same information for the alarm companies’ customers
    was not similarly pre-populated in Du-Comm’s comput-
    ers. When pressed, though, Du-Comm’s executive director
    testified that Du-Comm would be able to pre-populate its
    database to include address and other information for the
    alarm companies’ customers, which would then reduce the
    average dispatch times for those alarms to less than 30
    seconds, the same as if the alarm came in from the Dis-
    trict’s Station 3. Tegtmeyer 496; see also id. at 466-67.
    3. Radio Network Interference
    The evidentiary hearing also revealed that the
    District’s new wireless network operates on a less
    reliable frequency than fire and safety signals usually do.
    The FCC licenses two main types of private (i.e., not for
    commercial purposes) radio frequencies: “Public Safety
    Pool” and “Industrial/Business.” See 
    47 C.F.R. § 90.1
    .
    The frequency the District uses to connect the Keltron
    units at properties to Station 3 is an “Industrial/Business”
    frequency. 7 The industrial/business frequency pool is
    for commercial activities and other non-emergency ac-
    7
    We take judicial notice of the license for this frequency, call
    number WQKZ720, which labels the radio service as “IG –
    Industrial/Business Pool, Conventional.” Available at FCC

    tivities (such as the “operation of educational, philan-
    thropic, or ecclesiastical institutions”). See 
    47 C.F.R. § 90.35
    .
    This can include taxis, farmers, and other businesses.
    See In re Replacement of Part 90 by Part 88 to Revise the
    Private Land Mobile Radio Servs. & Modify the Policies
    Governing Them & Examination of Exclusivity & Frequency
    Assignments Policies of the Private Land Mobile Servs., 12
    F.C.C. Rcd. 14307, 14317, 14328 (1997) (“Similarly, frequen-
    cies initially set aside for taxicabs (Taxicab Radio Ser-
    vice) could be used in rural areas by farmers or in the
    operation of mines,” and describing industrial/business
    pool as for where, for the most part, “radio is used to
    support business operations”). In contrast, the public
    safety pool is for police activities, life-support services,
    and other activities involving important and emergency
    functions, including fire protection. 
    47 C.F.R. § 90.20
    .
    The alarm companies’ expert testified that the Indus-
    trial/Business Pool is less reliable than the Public Safety
    Pool because it is less secure and more susceptible to
    interruptions: “So someone with a taxicab company that
    you have no control over could be on this frequency, key
    a microphone for several minutes, and knock out several
    AES radios.” Fiore 519. See also In re Replacement of Part 90,
    12 F.C.C. Rcd. at 14312 (describing purpose of Public
    Safety Pool: “We considered these guidelines necessary
    to prevent overcrowding and to maintain the integrity
    of critical functions of the users included within
    this pool.”).
    Thus, the facts revealed by the evidentiary hearing
    substantially alter our understanding of the factual back-
    Nos. 12-2925 and 12-2981                                27
    ground of this case. We are no longer required to give
    the District the benefit of favorable inferences required
    by the summary judgment posture of ADT I, and we
    now know more about the District’s motives for its new
    monitoring plan and the shortcomings of that new plan
    in terms of safety and reliability.
    C. The Injunction Compliance with ADT I
    Significant new facts were also presented at the eviden-
    tiary hearing regarding our analysis in ADT I of the Dis-
    trict’s statutory authority under the Act. We held that
    the District had the regulatory authority to impose the
    “direct connect” requirement — which we understood to
    require that alarm signals be sent directly from properties
    to a Remote Supervising Station, rather than through
    the “middlemen” Central Stations. ADT I, 672 F.3d at
    496, 501. We found that opting for a Remote Supervising
    Station model instead of a Central Station model was
    “parallel” to the NFPA code so that the District had the
    authority under the Act to impose the requirement.
    The evidentiary hearing after our remand, however,
    revealed several facts that alter our analysis of the Dis-
    trict’s authority to impose the “direct connect” require-
    ment. These findings show that the District’s system is
    in fact not any more “direct” than the pre-ordinance
    private arrangements because it routes all signals through
    Station 3, whereas the prior arrangement similarly
    routed signals through Central Stations. Moreover,
    Station 3 itself does not comply with national standards.
    As actually implemented, therefore, the District’s
    28                                 Nos. 12-2925 and 12-2981
    “direct connect” requirement was not within its statutory
    authority to impose regulations “parallel to national
    standards.” See 70 Ill. Comp. Stat. 705/11. We therefore
    find that the district court acted within its discretion in
    enjoining the District from requiring all signals to route
    through Station 3 rather than Central Stations.
    1. Station 3 Not a Remote Supervising Station
    First, our reasoning in ADT I rested on the under-
    standing that the District’s Station 3 was the Remote
    Supervising Station — the facility receiving signals
    directly from protected properties with no intermediary
    stop in between. But it turns out that Station 3 is not the
    Remote Supervising Station. Du-Comm is the Remote
    Supervising Station, and signals are transmitted first to
    Station 3 before being sent on to Du-Comm. This means
    that the District’s “direct connect” requirement is no
    more “direct” than the pre-ordinance arrangements, as
    both arrangements involved transmitting signals from
    point A to B to C: A (property) to B (Station 3 or Central
    Station) to C (Du-Comm). The District argues that the
    transmission from Station 3 to Du-Comm is not a second
    transmission but an “autotransmission” such that the
    signal from the property should be understood to be
    transmitted from Station 3 to Du-Comm automatically.
    But this does not make the path from a protected
    property to Du-Comm “direct,” as the signal is still trans-
    mitted through Station 3, even if that happens automati-
    cally when the system is working as it is supposed to.
    Nos. 12-2925 and 12-2981                                  29
    2. Station 3 Does Not Meet NFPA 72 Code Standards
    In any event, Station 3 suffers from a second, more
    fundamental problem that was revealed during the
    evidentiary hearing. It does not conform to the
    applicable Code at all. The parties dispute this
    vigorously, beginning with which edition of the Code
    to use. The District has adopted the 2002 edition of
    NFPA 72, so we use that edition of the Code. (As we
    explain below, the District is not obligated to adopt or
    hold itself to a new edition.) Regardless, the 2002 and
    later editions have nearly identical language (albeit
    under different section numbers) in the relevant sections.
    Compare NFPA 72 § 8.2, 8.4 (2002), with NFPA 72 § 26.3,
    26.5 (2010).8
    More fundamentally, the parties dispute how the
    Code would characterize Station 3 and what require-
    ments apply to it as a result. The alarm companies argue
    that Station 3 should be considered a “subsidiary station”
    under the Code, which the Code defines as a separate,
    unsupervised station through which signals can be trans-
    mitted to a supervising station. See NFPA 72 § 3.3.192
    (2002). As a subsidiary station, Station 3 would be
    subject to the Code’s safety, reliability, and security
    standards for such a station. See NFPA 72 § 8.2.5.2 (2002).
    The District and Chicago Metro argue that Station 3
    is not a subsidiary station and is not subject to any
    8
    The parties submitted hard copies of the NFPA 72 standards,
    which are not otherwise readily available. We include the
    text of the relevant provisions in the Appendix.
    30                                 Nos. 12-2925 and 12-2981
    specific safety or reliability standards. They argue that
    the requirements for subsidiary stations are in the
    portion of the Code applicable to Central Stations, and
    because the District operates a Remote Supervising
    Station fire alarm system, those requirements cannot
    apply to Station 3.9 They argue instead that Station 3 is
    an “alternate location”:
    Where permitted by the authority having jurisdic-
    tion, fire alarm and supervisory signals shall be per-
    mitted to be received at an alternate location
    approved by the authority having jurisdiction.
    NFPA 72 § 8.4.2.1.2.* (2002).
    The term “alternate location” is not defined in the Code,
    and the Code does not appear to articulate any require-
    ments for “alternate locations.” We asked counsel for
    the District during oral argument what requirements
    such an alternate location would need to meet, and he
    identified none. So the District’s apparent position is
    that the Code considers Station 3 to be an “alternate
    location” under section 8.4 and as such does not subject
    it to any requirements for safety, security, and reliability.
    We find the alarm companies’ position — that Station 3
    is at least subject to the requirements of a “subsidiary
    9
    The Code includes separate sections governing Central
    Station fire alarm systems and Remote Supervising Station
    fire alarm systems: section 8.2 governs Central Stations while
    section 8.4 governs Remote Supervising Stations. See NFPA 72
    § 8.2, 8.4 (2002).

    station” under chapter 8 — to be more persuasive than
    the District’s position that the station is subject to no
    requirements at all.
    There are several problems with the District’s inter-
    pretation. First, the section it cites as permitting
    signals to be routed through an “alternate location”
    actually refers to the destination location — the Remote
    Supervising Station itself (like Du-Comm), not an inter-
    mediary location such as Station 3. See NFPA 72 § 8.4.2.1
    (2002) (permitting two options for facilities to serve as
    the remote supervising station itself, including an “alter-
    nate location”). Any facility serving as the destination
    remote supervising station must meet substantive re-
    quirements, including that the “remote supervising
    station shall have not less than two trained and
    competent persons on duty at the remote supervising
    station at all times.” NFPA 72 § 8.4.3.5.1 (2002). This
    section does not say that the District may designate an
    “alternate location” as an intermediary station through
    which to route signals before they arrive at the Remote
    Supervising Station. In fact, nothing in section 8.4 contem-
    plates that alarm signals under a remote supervising
    system would be transmitted through an intermediary
    station at all. Section 8.4 does contemplate retransmis-
    sion in subsection 8.4.3.4, but that applies to transmis-
    sions from the Remote Supervising Station to another
    location. NFPA 72 § 8.4.4.1 (2002) (alarm signals shall
    be immediately retransmitted if the Remote Supervising
    Station is at a location other than the public fire services
    communications center).
    32                               Nos. 12-2925 and 12-2981
    Second, even if section 8.4’s reference to an “alternate
    location” could refer to an intermediary station between
    properties and the remote supervising station, it is
    unlikely that such a station would not be subject to any
    NFPA requirements. The reference note to that section
    indicates: “A listed central station might be considered
    an acceptable alternate location for receipt of fire alarm
    and supervisory signals.” NFPA 72 § A8.4.2.1.2. (2002)
    (Such an arrangement was precisely how the District
    operated before the 2009 ordinance, with Central Stations
    receiving alarm and supervisory signals.) The Code is
    otherwise silent as to what an “alternate location” may
    be or entail, but its only guidance indicates that the
    Code contemplates that it could be a Central Station,
    and Central Stations are held to higher standards than
    subsidiary stations. Compare NFPA 72 § 8.2.5.2 et seq.
    (2002) (listing requirements for subsidiary stations),
    with § 8.2.6.2.1 (requirements for Central Stations, in-
    cluding two supervising personnel at all times, which
    match the personnel requirements for Remote Super-
    vising Stations under section 8.4.3.5.1). Thus, on our
    reading, section 8.4 does not contemplate an intermediary
    station at all, but rather transmission from properties
    directly to a supervised station (either a Central Station
    or another location meeting the personnel requirements
    of section 8.4.3.5.1).
    Third, the District’s position seems implausible, as we
    doubt that the Code would permit a fire district to do
    what the District has attempted to do here: reroute trans-
    missions to a receiver in an unsupervised room with
    no back-up equipment and no mechanism in place to
    Nos. 12-2925 and 12-2981                               33
    restore signal transmission quickly if there are technical
    problems. Chicago Metro’s witness Larry Coveny testified
    that if the receiver at Station 3 stopped functioning, the
    following steps would have to be taken to repair it: Du-
    Comm would have to receive a signal that it was down,
    Du-Comm would then call the District, someone at the
    District would then call Chicago Metro, and Chicago
    Metro would then send someone out to fix the head-end
    unit. Coveny 453. This process could likely take several
    hours, which we doubt the Code should be interpreted
    to permit, since it requires subsidiary stations under
    section 8.2 to have redundant equipment functioning
    as back-up within 90 seconds. See NFPA 72 § 8.2.5.2.3.
    In contrast, the alarm companies’ argument that Station
    3 is a “subsidiary station” and must meet the applicable
    requirements is a more sensible reading. A “subsidiary
    station” is defined as
    a normally unattended location that is remote from
    the supervising station and is linked by a communica-
    tions channel(s) to the supervising station. Intercon-
    nection of signals on one or more transmission chan-
    nels from protected premises with a communications
    channel(s) to the supervising station is performed
    at this location.
    NFPA 72 § 3.3.192 (2002).
    This describes Station 3 in all material respects: it is
    unattended, remote from the remote supervising station
    (Du-Comm), linked by a communications channel (the
    wireless radio network) to Du-Comm, and connects
    signals from properties to Du-Comm. The Code defines
    34                                Nos. 12-2925 and 12-2981
    a “supervising station” as “a facility that receives signals
    and at which personnel are in attendance at all times to
    respond to these signals.” NFPA 72 § 3.3.193 (2002).
    We recognize that the requirements for subsidiary
    stations are found in section 8.2, which applies to
    Central Station fire alarm systems, but this seems the
    best fit for Station 3, as section 8.4 does not contemplate
    an intermediary station at all.
    Thus, either the Code does not contemplate an inter-
    mediary retransmitting station at all, or such a station is
    a “subsidiary station” and must meet the requirements
    of section 8.2.5. We think the latter is the better reading.
    So did the alarm companies’ expert, Louis Fiore, who
    helped write the Code. He said that “when we wrote 8.4,
    we didn’t envision this configuration” (referring to an
    intermediary station between properties and the Remote
    Supervising Station), but that he would instead apply
    the requirements for a subsidiary station from section 8.2
    to such a station. See Fiore 109.
    As the district court correctly found, Station 3 does
    not meet the requirements of section 8.2.5.2 (including
    subsection 8.2.5.2.3). It does not have the necessary equip-
    ment for a backup channel to be “operational within
    90 seconds,” § 8.2.5.2.3, and it does not meet the inde-
    pendent certification requirements of “UL 827,” see
    § 8.2.5.2, which require redundant equipment and chan-
    nels. Station 3 is not certified by UL 827 and there is only
    one receiving unit at Station 3. Coveny 453 (only one
    receiving unit at Station 3); Fiore 126-27 (no evidence
    that Station 3 meets NFPA Code).
    Nos. 12-2925 and 12-2981                                 35
    Thus, the evidentiary hearing revealed that Station 3
    does not meet the Code standards, leaving plaintiffs’
    Central Stations as the only Code-compliant means of
    transmitting alarm signals from properties in the
    District to Du-Comm. In light of these facts, the district
    court acted within its discretion to require the District
    to shut down Station 3. Because the Code requires com-
    mercial properties to have fire alarm monitoring, and
    the injunction put Station 3 out of commission, only
    Central Stations are currently a viable option for alarm
    monitoring in the District. The injunction therefore ap-
    propriately required the District to permit signals to
    be sent to Central Stations so that fire alarm monitoring
    in the District would remain compliant with the
    NFPA Code.
    D. Injunction as Applied to Du-Comm
    The injunction also includes provisions requiring the
    District to enlist Du-Comm’s cooperation in enabling
    Central Stations to monitor. First, in light of the district
    court’s finding that Station 3 was not in compliance with
    the Code and that the District must therefore permit
    Central Stations to transmit and monitor alarm signals,
    the district court enjoined the District to:
    direct DuComm to cooperate as reasonably required
    by the Alarm Companies to implement a procedure
    so that central stations can automatically retransmit
    fire alarm signals to the DuComm SIS computer and,
    to the extent that DuComm upgrades its CAD system
    36                                Nos. 12-2925 and 12-2981
    to receive fire alarm signals through NLETS, ASAP
    to PSAP transmissions.
    MPI ¶ 5.
    Second, given that fire alarm signals received from
    Central Stations would take 30 seconds longer to
    dispatch than those received from Station 3, but only
    because the relevant addresses were not pre-populated
    in Du-Comm’s computers, the district court also
    ordered the District to:
    direct DuComm to cooperate as reasonably required
    by the Alarm Companies in the implementation of a
    procedure to populate the DuComm CAD system
    with the necessary information about the Commercial
    Accounts to reduce the time lag in dispatching emer-
    gency vehicles and fire trucks, consistent with the
    method now being employed by DuComm for the
    District’s Commercial Accounts.
    MPI ¶ 4.
    Appellants and intervenor Du-Comm argue that
    these provisions of the injunction improperly bind Du-
    Comm, which is not a party to the suit. Federal Rule of
    Civil Procedure 65 permits courts to enjoin a party’s
    “officers, agents, servants, employees, and attorneys” and
    “other persons who are in active concert or participa-
    tion” with a party or its officers or agents, so long as
    those persons have received actual notice of the injunc-
    tion. Fed. R. Civ. Proc. 65(d)(2)(B)-(C). The parties dispute
    both whether Du-Comm is an “agent” of the District, given
    that it is governed and directed by a board made up of
    Nos. 12-2925 and 12-2981                                37
    representatives from its member agencies, including the
    District, see Tegtmeyer 501; Freeman 277-78, and whether
    it received sufficient notice of the injunction. District
    courts have broad discretion to enjoin third parties who
    receive appropriate notice of the court’s injunctive
    order. H-D Michigan, LLC v. Hellenic Duty Free Shops S.A.,
    
    694 F.3d 827
    , 842 (7th Cir. 2012).
    As interesting as the problem of the precise legal status
    of Du-Comm may be, the injunction does not apply
    directly to Du-Comm. It directs the District to “direct Du-
    Comm to cooperate.” And Du-Comm’s executive
    director Brian Tegtmeyer testified that Du-Comm is able
    to cooperate with the District in the ways described by
    those paragraphs. At the evidentiary hearing, he testified
    about Du-Comm’s ability to pre-populate its computer
    with the addresses and information of the alarm com-
    panies’ customers. In response to a question asking “if
    the alarm companies gave you the same data and you
    assign a position for each of those commercial accounts,
    you could input it into the same computer, correct?”
    Tegtmeyer answered, “I could input the same information
    into the computer, the dispatch computer.” Tegtmeyer 496;
    see also id. at 489-90 (answering yes, that Du-Comm
    could prepopulate if Central Stations gave the informa-
    tion, but that “we have never discussed the methodol-
    ogy” and “we haven’t done it,” but that Du-Comm
    would not need any more equipment to do it).
    As to the fifth paragraph, although Du-Comm does not
    yet have the capacity to receive the specific type of con-
    nection that the alarm companies’ expert testified
    38                                Nos. 12-2925 and 12-2981
    would allow Central Stations to transmit signals directly
    to Du-Comm’s computer, the expert testified that
    enabling Du-Comm’s computer to do so would involve
    a software change that would be an “easy fix.” Fiore 122.
    We read paragraphs four and five of the injunction
    as imposing a direct obligation on only the District, but
    with the understanding that Du-Comm appears ready
    to cooperate with the District in carrying out the require-
    ments of those paragraphs. If Du-Comm refuses the
    requests of its member agency, the District, the district
    court may need to consider (a) whether the existing
    injunction supports holding Du-Comm in contempt
    under Rule 65, particularly whether Du-Comm is an
    “agent” of the District and whether Du-Comm
    received sufficient notice of the injunction for it to be
    bound directly by the injunction, or (b) whether to
    consider modifying the injunction after appropriate
    proceedings so as to remove any arguable uncertainty.
    See Fed. R. Civ. P. 65(d)(2)(B); see also Lake Shore Asset
    Management Ltd. v. Commodity Futures Trading Comm’n,
    
    511 F.3d 762
    , 767 (7th Cir. 2007) (Rule 65’s notice require-
    ment means party’s agent falls under Rule 65(d)(2)(B)
    or (C) only after the agent in question “is given notice
    and an opportunity to be heard,” including the oppor-
    tunity to present evidence on the question of its
    relation to the party). Although Du-Comm certainly
    now has notice of the injunction and has had the oppor-
    tunity to dispute its relationship to the District in
    this appeal, we need not resolve here whether that meets
    Rule 65’s requirements, nor whether Du-Comm is an
    agent of the District.
    Nos. 12-2925 and 12-2981                              39
    Unless and until Du-Comm changes its mind about pre-
    populating its databases or reprogramming its computer
    so Central Stations can automatically transmit signals
    there, we need not address those issues. Certainly, the
    evidence appears undisputed that these are steps
    that would enhance safety by improving response
    time and transmission reliability, and we have difficulty
    imagining why Du-Comm would resist such improve-
    ments. Given Tegtmeyer’s testimony about Du-Comm’s
    ability to cooperate on these safety measures, we would
    be surprised if Du-Comm chose to contest further the
    agency and notice issues under Rule 65. If it does,
    the district court can take appropriate steps to ensure
    compliance with its injunction.
    E. The New Ordinance
    For the reasons above, we find that the injunction
    appropriately prohibits the District from enacting the
    basic components of its monitoring plan in light of the
    facts found at the evidentiary hearing because the
    District lacks the legal authority to enact its plan. The
    District now claims that its 2012 ordinance avoids the
    problems posed by its 2009 ordinance and that the in-
    junction improperly disregarded it. Rather than
    analyzing the new ordinance in light of ADT I and the
    evidentiary hearings, the district court enjoined the
    District from enforcing the new ordinance and modified
    the original ordinance by redacting it to conform with
    ADT I and its new factual findings. MPI ¶¶ 20, 1. We
    can understand the district court’s reluctance to
    40                                Nos. 12-2925 and 12-2981
    undertake the task of modifying its work on the injunc-
    tion to account for the District’s last-second effort to
    avoid further litigation. The District passed the new
    ordinance just days before its proposed findings and
    conclusions and supporting memoranda for the modified
    preliminary injunction and summary judgment were due.
    But although the 2012 ordinance did not moot the
    controversy, it did replace the 2009 ordinance, so the
    2012 ordinance is the relevant District action for the
    purposes of our analysis and we will directly review its
    legality. This keeps the courts from standing on
    the shaky ground of requiring the District to revive its
    already-repealed ordinance. See, e.g., De Soto Sec. Co. v.
    C.I.R., 
    235 F.2d 409
    , 411 (7th Cir. 1956) (“The courts can
    only interpret congressional acts. They cannot legislate.”).
    We find that the following portions of the new
    ordinance must be struck to conform it to our opinion
    today and in ADT I:
    <   In section 2.3, the last sentence shall be struck:
    “The District shall, however, maintain the Commu-
    nications Board for purposes of receiving and
    relaying to Du-Comm, Generated Signals transmit-
    ted from Affected Properties via networks main-
    tained by Licensed Alarm companies, as contem-
    plated by the provisions of this Ordinance.”
    This sentence conflicts with paragraph 7 of the injunc-
    tion, which requires the District to shut down its alarm
    board at Station 3. Because we agree with the district
    court that Station 3 does not comply with the relevant
    portions of the Code, the new ordinance cannot permit
    Nos. 12-2925 and 12-2981                                41
    Station 3 to continue operating, and this sentence must
    be struck.
    <   Section 2.4 shall be redacted as follows:
    The Owners of all Affected Properties, on or before
    the date for compliance set forth in Section 4.1
    hereof, shall engage a Licensed Alarm Company
    of the Owner’s choice to provide a wireless radio
    connection capable of instantly transmitting all
    Generated Signals directly to the Communications
    Board maintained by the District for purposes of
    receiving, identifying and instantly transmitting
    said Generated Signals by wireless radio direct
    connection to Du-Comm. Said Generated Signals
    shall be delivered directly to the District’s Commu-
    nications Board by the Owner’s alarm company by
    the method contemplated by Section 3.1 hereof, or
    by such alternate method as may be approved by
    the Chief of the District’s Fire Prevention Bureau
    (“Bureau Chief”) upon application as provided in
    Section 3.2, which said approval shall not be
    unnecessarily withheld.
    All Affected Properties shall be equipped with
    wireless radio transmitters capable of sending
    Generated Signals through a Licensed Alarm
    Company’s wireless radio network, as set forth in
    Section 3.1 hereof, which network shall be directly
    connected to the District’s Communications Board.
    Said wireless transmitters shall each have at least
    60 hours of secondary power.
    The District cannot require the alarm companies to
    transmit signals through a wireless network “directly
    42                                  Nos. 12-2925 and 12-2981
    connected to the District’s Communications Board”
    because Station 3 does not comply with the Code. The
    District also cannot require alarm companies to use its
    wireless radio network exclusively, as that network relies
    on the receiver at Station 3. Moreover, the District’s
    wireless network is compatible with only one type of
    wireless radio transmitter. See Coveny at 376, 439. As we
    discussed above, requiring a specific type of transmitter
    raises substantial antitrust issues. But because we find
    that the District can no longer operate Station 3 or
    require signals to be transmitted through it, we need not
    resolve that issue now.
    <   Section 2.5 is struck in its entirety, as the District
    is not permitted to operate its “Communications
    Board,” i.e., Station 3.
    <   Section 2.6 is struck.
    To the extent that the fees Du-Comm assesses are
    derivative fees that the District would not have the author-
    ity to assess on its own, and because the District cannot
    assess fees for fire alarm signaling and monitoring, Du-
    Comm cannot assess such fees on the District’s behalf.
    See ADT I, 672 F.3d at 504-05.
    <   In section 3.1, all text following “All Generated
    Signals shall be transmitted through a wireless
    radio network operated and maintained by a
    Licensed Alarm Company,” is struck.
    The District cannot require the alarm companies to
    connect to Station 3, which renders the rest of the
    language about access to the board and applications
    for such access superfluous.
    Nos. 12-2925 and 12-2981                                43
    <   Section 3.2 is struck in its entirety.
    No approval process is necessary because the District
    is not permitted to require direct connection to the
    board at Station 3 or to Du-Comm.
    Given the severability clause in section 8.1, all other
    portions of the new ordinance may remain. They need
    not be struck, though many will likely be rendered some-
    what irrelevant given what remains of the ordinance.
    Substantively, the essence of what remains is that com-
    mercial property owners are required to use wireless
    transmission through private alarm companies.
    F. Remaining Issues
    We have rejected the District’s and Chicago Metro’s
    primary arguments about the district court’s compliance
    with ADT I, Du-Comm’s involvement, and the new
    ordinance. In addition to these arguments, the District and
    Chicago Metro complain about numerous other aspects of
    the injunction. We have considered their arguments and
    find little merit. Many of their arguments are undeveloped
    and unsupported. See United States v. Berkowitz, 
    927 F.2d 1376
    , 1384 (7th Cir. 1991) (“We repeatedly have made
    clear that perfunctory and undeveloped arguments . . . are
    waived (even where those arguments raise constitu-
    tional issues).”). But a few of their arguments raise
    valid concerns with the injunction, so we modify the
    injunction in a few minor respects to account for
    those arguments, in addition to the modifications we
    made to the 2012 ordinance.
    44                                Nos. 12-2925 and 12-2981
    1. Refunds to Subscribers
    First, we agree that paragraph 17 of the injunction is
    problematic. It requires the District to “refund to the
    affected Commercial Accounts all monies collected by
    [the] District for fire alarm monitoring since the inception
    of the Ordinance.” MPI ¶ 17. This is problematic because
    the subscribers who would receive such refunds are not
    parties to this case. See, e.g., McKenzie v. City of Chicago,
    
    118 F.3d 552
    , 555 (7th Cir. 1997) (“The fundamental prob-
    lem with this injunction is that plaintiffs lack standing
    to seek — and the district court therefore lacks authority
    to grant — relief that benefits third parties.”). While we
    realize it may seem more efficient to deal with custom-
    ers’ potential claims against the District in this
    proceeding, the question of whether and what amount
    of refunds such subscribers should receive is sufficiently
    complex that it warrants more attention and process
    than we can give it on this record. For example, the sub-
    scribers who paid for the District’s monitoring services
    at least received those monitoring services, even if the
    District was not permitted by statute to provide them
    and even if the quality and reliability were worse than
    promised. So the subscribers may not be entitled to a
    complete refund, but rather the refund may need to be
    mitigated to account for the reasonable value of the
    alarm monitoring services the District actually provided
    them during that time. Cf. 26 Williston on Contracts § 68:1
    (4th ed.) (award for reasonable value of services rendered
    is permitted under unjust enrichment, even when “the
    contract is unenforceable because of a lack of capacity
    of one of the parties”).
    Nos. 12-2925 and 12-2981                                      45
    2. Adopting the Code
    Paragraph 9 of the injunction requires the District
    to “adopt the current version of the NFPA Code” and to
    “adopt such newer versions when they are issued.” MPI
    ¶ 9. We do not see a legal basis for such a requirement.
    Rather, courts have acknowledged which version of
    NFPA codes municipalities adopt without commenting
    on the propriety of having adopted a version from years
    past. See, e.g., Alliance for Mentally Ill v. City of Naperville,
    
    923 F. Supp. 1057
    , 1062 (N.D. Ill. 1996) (noting “Naperville
    adopts the 1991 version of the Life Safety Code (“LSC”),
    published by the National Fire Protection Association
    (“NFPA”)”), abrogated on other grounds by Hemisphere
    Bldg. Co. v. Village of Richton Park, 
    171 F.3d 437
     (7th
    Cir. 1999). The Code itself includes no requirement that
    municipalities adopt the most recent version. Its “Code
    Adoption Requirements” section states merely that “[t]his
    Code shall be administered and enforced by the authority
    having jurisdiction designated by the governing author-
    ity.” NFPA 72 § 1.7 (2002) (language remains same
    through 2013 version). Without a legal basis for
    requiring that the District adopt the most recent version
    of the Code and continue to do so with every revision,
    paragraph 9 of the injunction must be removed.
    3. Timing
    We raise a final concern with the modified permanent
    injunction — that its duration is indefinite. It is of course
    a permanent injunction, but we can easily imagine that
    at some point in the future, the circumstances giving
    46                                  Nos. 12-2925 and 12-2981
    rise to the injunction will change and the injunction
    may therefore also need to change or may no longer be
    necessary. The district court retains the power to
    modify the injunction further if the circumstances so
    warrant. Given that the injunction addresses this
    particular time, current technology, and a current set of
    market problems, we are confident that the district
    court will keep the door open to necessary modifications
    in the public interest, while keeping in mind the themes
    and tension underlying this case: balancing a municipal
    entity’s legitimate regulatory authority while protecting
    the market from unlawful monopolistic activity.
    III. Conclusion
    The modified permanent injunction generally comports
    with ADT I and appropriately enjoins the District’s
    activity with regard to alarm monitoring in the District.
    The injunction must be modified as noted above with
    regard to the new ordinance, the subscriber refunds,
    and requiring the District to adopt a certain version of
    the NFPA Code. But it is otherwise a reasonable exercise
    of the district court’s discretion in light of all the evidence,
    particularly the testimony at the evidentiary hearing
    following ADT I. The injunction is forceful, but
    given the District’s and Chicago Metro’s history of recalci-
    trance throughout this litigation, the district court was
    justified in taking strong measures.
