UL-Listed Alarm Monitoring Companies Compared: National Providers vs. Wholesale Central Stations

Short answer (as of October 2026): UL-listed alarm monitoring companies come in two forms. National end-to-end providers such as Everon (formerly ADT Commercial), Securitas Technology and Johnson Controls, plus regional full-service firms like DGA Security and APS Corporation, sell you the system and monitor it from their own UL-listed centers. Wholesale central stations such as COPS Monitoring, Rapid Response Monitoring and CMS (Criticom) also state UL listings but sell only through local alarm contractors. One distinction governs everything: a UL-listed central station describes the monitoring facility, while a UL certificate for your premises describes your installed system. UL says insurers and code officials often require the second.

If your insurer, lender or fire marshal has written "UL-listed monitoring" into a requirement, the provider's logo is the smaller decision. What satisfies the requirement is the right UL service category, often backed by a Protected Property Alarm System Certificate issued for your building. That can come from a national brand or from a screened local contractor monitoring through a UL-listed wholesale station, usually at different monthly rates, contract lengths and equipment-ownership terms. This guide names the companies, explains what each can and cannot issue, and shows how to verify a claim in UL's public directory before you sign.

UL-listed central station vs. UL certificate for your building

A UL-listed central station is a monitoring facility that UL Solutions has audited against UL 827, the Standard for Central-Station Alarm Services, and re-audits every year. A UL certificate for your premises (formally a Protected Property Alarm System Certificate) is a document issued for one specific building, declaring that the installed alarm system and the services behind it meet the UL category it names. Signing with a company whose station is listed does not, by itself, produce a certificate for your property.

UL 827 covers the station: staffing, backup power, redundancy, physical security, signal handling and record-keeping. UL's central station service certification page states that stations must demonstrate compliance with UL 827 before listing and are audited annually afterward. Two category codes matter to a commercial buyer:

• CPVX, Central Station Burglar Alarm Systems. The full-service intrusion category. Opening and closing schedules are agreed in advance, deviations are investigated, and runners are on duty to respond to protected properties.
• UUFX, Central Station Protective Signaling Services. The central station fire alarm category. UL describes it as covering the elements NFPA 72 assigns to central station service: installation at the protected premises, signal monitoring, retransmission and record-keeping, testing, maintenance, runner service and certification.

The same UL page defines three kinds of company that can deliver that service, and the distinction decides who can hand you a certificate:

1. Full-service company. Delivers every element (installation, monitoring, testing, maintenance, runner service) and can issue UL certification for a protected property.
2. Monitoring-only company. Provides signal monitoring and supervision under contract to companies authorized to issue UL certification. It does not issue certificates itself.
3. Alarm service local company. Installs, tests, services and maintains the system and provides runner service, while subcontracting monitoring to a UL-certified central station.

Who can issue a Protected Property Alarm System Certificate? UL states that stations listed in a full-service category (CPVX or UUFX) can issue Protected Property Alarm System Certificates to their customers through CertsView, UL's certificate management application, and that these certificates "are often required by insurance companies and code officials." A monitoring-only station cannot issue one for you, and neither can a local installer with no UL listing of its own. A certificate reaches you one of two ways: from a full-service listed company that both installed and monitors the system, or from a UL-listed local alarm service company working in a contractual partnership with a listed central station. UL notes NFPA 72 allows both arrangements.

Can a local alarm contractor give you UL-listed monitoring without owning a central station? Yes: UL's "alarm service local company" category exists for contractors that install and maintain the system while subcontracting monitoring to a UL-certified central station, so a listed local company monitoring through COPS, Rapid Response or CMS can deliver UL-listed monitoring, and a premises certificate where it holds the appropriate listing. What you must check is that the contractor itself appears in UL Product iQ, not just the station it uses.

UL-listed alarm monitoring companies compared

The table groups alarm monitoring companies by how you buy them. National and regional full-service providers sell direct: one contract covers equipment, installation, monitoring and service. Wholesale stations never contract with a building owner; the local alarm security monitoring company you hire holds your account there, and its name, listing and license need verifying alongside the station's. Every listing claim below is the company's own statement, and the final column tells you what to confirm in UL's directory.

Last verified: October 3, 2026. Listing status changes; confirm every entry in UL Product iQ before relying on it.

Everon (formerly ADT Commercial)

Everon is the business that operated as ADT Commercial. GTCR announced on October 2, 2023 that it had completed its acquisition of ADT's commercial fire and security segment and that ADT Commercial would rebrand as Everon. On its monitoring services page, Everon states that "every Everon monitoring center across the United States is listed by Underwriters Laboratories Inc. (UL)" and that its centers hold TMA Five Diamond certification (accessed October 2026). It sells intrusion, fire and sprinkler, video and environmental monitoring direct to commercial customers, a full-service company in UL's terms. Existing ADT Commercial accounts should search Everon's legal entity in Product iQ.

Securitas Technology

Securitas completed its acquisition of Stanley Security on July 22, 2022, so older Stanley monitoring agreements now sit under Securitas Technology. Its security monitoring page states (accessed October 2026) that its monitoring adheres to Underwriters Laboratories, New York City Fire, FM Global and SOC 2 Type 2 standards, that it holds TMA Five Diamond recognition, and that it operates more than 40 monitoring centers globally with over 2,000 operators. Product iQ shows a UUFX entry under Securitas Technology Corporation. Because the footprint is global, ask which US center will hold your account and confirm that center's listing.

Johnson Controls

Johnson Controls has run the former Tyco Integrated Security business since the companies completed their merger in September 2016. Its commercial security page states that it offers "24-hour monitoring by skilled professionals and UL-certified facilities across North America," covering security alarm monitoring and fire monitoring (accessed October 2026). Product iQ carries a CPVX listing for Johnson Controls Security Solutions LLC. The business is oriented to enterprise, institutional and multi-site accounts, and the page publishes neither a monitoring center count nor a TMA Five Diamond claim.

DGA Security (regional example)

DGA Security, headquartered in New York City, is a model of the regional full-service company. Its alarm monitoring page states that it monitors from its own centers rather than outsourcing, that it holds UL listings in Central Station Burglar Alarm, Central Station Protective Signaling Services and Mercantile Burglar Alarm Systems, and that it is FDNY approved and TMA Five Diamond certified (accessed October 2026). That combination of categories is what a jeweler, gallery or cannabis operator with a demanding insurer tends to need. DGA also states it provides local service nationwide for multi-location customers.

APS Corporation (regional example)

APS Corporation, founded in 1981 and now part of Pye-Barker Fire & Safety, is a New Jersey security and fire alarm integrator. Its central station monitoring page states that its "full-service Underwriters Laboratories (U.L.) listed Central Station Monitoring Center" monitors fire and security systems around the clock (accessed October 2026). It contracts directly with end customers. Treat it as representative of the regional full-service companies that own a listed station; most metro areas have at least one.

COPS Monitoring

COPS Monitoring, founded in 1978, states that it is "100% wholesale": it does not sell, install or own accounts. Its About page states that it operates three UL-listed, real-time load-sharing monitoring stations in New Jersey, Florida and Texas, and that it is UL listed, FM approved, IQ certified and TMA Five Diamond certified (accessed October 2026). You cannot sign with COPS; your contractor does, and your account is monitored under that contractor's name. COPS also offers dealers "certificates of monitoring," which are not UL certificates, so be precise about which document your insurer wants.

Rapid Response Monitoring

Rapid Response serves independent dealers, enterprise integrators and commercial fire integrators from two hardened command centers in Upstate New York and Southern California, plus a customer care center in Nevada. Its licensing and certifications page states it is listed by UL for UUFX Protective Signaling Services, CRZM and CRZH National Industrial Security Systems, CVSG Mercantile Burglar Alarm Systems and UUFO Hosted Central Station Service, and that it is FM approved under Approval Standard 3011 and approved to monitor fire alarms in New York City (accessed October 2026). Note the burglar category on that list is Mercantile (CVSG), not CPVX. If your insurer specifies CPVX by name, confirm the match before assuming the station qualifies.

CMS (Criticom Monitoring Services)

CMS, legally Security Monitoring Services, Inc. d/b/a Criticom Monitoring Services, has been a wholesale partner to alarm dealers since 1984 and describes itself as the largest commercial and industrial wholesale monitoring company in the United States. Its About page states it runs three redundant monitoring centers with load balancing, its solutions page states that fire signals are handled by "100% UL Fire Certified staff," and the site displays UL and FM marks (accessed October 2026). Like COPS, it is reached only through your dealer. Other wholesale stations exist (National Monitoring Center and Affiliated Monitoring among them); the same Product iQ check applies to each.

Which route fits you: national provider or local contractor on a wholesale station

A national full-service provider suits multi-site portfolios that want one contract, one portal and one escalation path, and it is the simplest way to get premises certificates issued and renewed from a single source. A screened local contractor monitoring through a UL-listed wholesale station suits single buildings and small regional groups, usually with more flexibility on panel choice, contract length and who owns the communicator. Neither route is inherently "more UL" than the other; the certificate is what the insurer reads.

• Multi-site or single site? Ten buildings in six states argue for a national account team. One warehouse argues for a local company whose technician can be on site in an hour, which matters for runner service and the annual certificate inspection.
• Existing panel or new install? Many commercial alarm panels can be taken over by a new monitor alarm company if they are non-proprietary and you hold the installer codes. A panel locked to the current provider has to be replaced to switch routes, which changes the math.
• Contract length and renewal. Commercial monitoring agreements commonly run 36 to 60 months with automatic renewal unless you cancel inside a notice window. Our business alarm monitoring hub covers the clauses to negotiate, so we will not repeat them here.
• Equipment ownership. A low monthly rate frequently means the provider retains the panel or the cellular communicator. Get ownership of both in writing, whichever route you take.

Does UL-listed monitoring cost more per month than standard monitoring? In the quotes we see, the station's listing is seldom priced as its own line item; it is a property of the facility, not of your account. What raises the price is the service a premises certificate requires: higher-grade equipment, line security or supervised dual-path communication, runner service and annual inspection. Our published ranges are $30 to $75 a month for basic intrusion monitoring and $60 to $150 a month with supervised fire reporting; a certificated system tends to sit toward the top of those bands rather than outside them.

Do you need UL-listed monitoring for fire alarms as well as burglar alarms? For fire, the answer usually comes from code rather than your insurer. UL describes central station fire alarm service as the set of NFPA 72 elements delivered through a listed station, and where code requires a commercial fire alarm to be monitored, the authority having jurisdiction will generally specify the kind of supervising station it accepts. Confirm the category (UUFX for central station service) with your fire marshal and price the fire line separately; our commercial fire alarm cost guide covers monitoring and communicator costs on that side.

Where does TMA Five Diamond fit? UL audits the facility and service against UL 827. The Monitoring Association's Five Diamond designation certifies that every operator in the center has completed TMA's training and that the center meets its operational standards, renewed annually. It is a quality signal worth asking for, but it does not satisfy a requirement written as "UL listed" or "UL certificated," and it cannot produce a premises certificate.

How to verify a UL claim in 10 minutes

UL Product iQ is a free, public directory of every company UL has listed, searchable by company name and category code; UL notes that code authorities use it to find qualified alarm companies in their jurisdiction. A sales deck is not evidence; the directory entry is.

1. Search the legal entity in Product iQ. Use the exact company name that will appear on your contract ("Securitas Technology Corporation," not "Securitas"). If you are buying through a local contractor, search the contractor and the central station separately. A free account may be required to view full records.
2. Confirm the category code matches your requirement. Look for CPVX if the requirement is central station burglar alarm service, UUFX if it is central station fire alarm service, and check that the listed location is the station that will hold your account. A UUFX-only listing does not satisfy a burglar requirement, and a Mercantile (CVSG) listing is not CPVX.
3. Ask for the certificate number and issuing company. If you need a Protected Property Alarm System Certificate, ask which listed company will issue it, in what category, and when it expires. Listed companies issue these through UL's CertsView system, and UL's annual audit of full-service companies includes visits to selected certificated properties, so a legitimate issuer can produce one without difficulty.

What to ask when your insurer or AHJ requires UL

Get the requirement in writing from whoever imposed it, then put the same questions to every provider. Ask your insurer or code official:

• Do you require a UL-listed central station, or a UL certificate issued for this property? (The second implies the first.)
• Which category must the certificate name: CPVX, UUFX, Mercantile, or another?
• Are there extent-of-protection or line-security grades that must appear on the certificate?
• Does the certificate need annual renewal, and who receives the copy?

Then ask every alarm monitoring company that quotes you:

• Which central station, by legal name and address, will hold my account, and in which UL categories is it listed?
• Are you a full-service listed company, a monitoring-only station, or an alarm service local company under UL's definitions? If the last, which listed company issues my certificate?
• Will you issue a Protected Property Alarm System Certificate for this address, in the category my insurer named, and at what added cost?
• Who performs runner service and the annual certificate inspection, and from how far away?
• Who owns the panel and communicator at the end of the term, and can another listed company take over the system without replacing it?
• What are the term, auto-renewal and cancellation terms, stated separately for intrusion and fire?

Buyers in regulated categories should add one more. Cannabis operators, for example, face state rules on continuous alarm monitoring and licensed alarm contractors on top of whatever their insurer specifies, so the contractor's state alarm license has to be verified as carefully as the station's UL listing.

Frequently asked questions

What companies offer UL-listed commercial alarm monitoring in the US?

As of October 2026, national providers that state their monitoring centers are UL listed include Everon (formerly ADT Commercial), Securitas Technology and Johnson Controls, with regional full-service firms such as DGA Security and APS Corporation. Wholesale stations that state UL listings, such as COPS Monitoring, Rapid Response Monitoring and CMS, serve businesses only through local alarm contractors. Verify each in UL Product iQ before signing.

What is the difference between a UL-listed central station and a UL certificate for my building?

A UL-listed central station is a monitoring facility audited annually against UL 827. A UL certificate for your premises, the Protected Property Alarm System Certificate, is issued for one address and declares that the installed system and services meet a named UL category. UL notes that insurers and code officials often require the certificate, which only a UL-listed company in a full-service category can issue.

Who can issue a UL Protected Property Alarm System Certificate?

Only a UL-listed alarm company in a full-service category such as CPVX (burglar) or UUFX (fire), using UL's CertsView application. Monitoring-only stations and unlisted local installers cannot. A listed local alarm service company partnered with a listed central station can.

Is Everon the same company as ADT Commercial, and are its monitoring centers UL listed?

Yes. ADT Commercial was acquired by GTCR in a transaction completed on October 2, 2023, and rebranded as Everon. Everon states that every one of its monitoring centers in the United States is listed by UL. Confirm the current legal entity in Product iQ.

What are wholesale central stations, and can a business sign with them directly?

Wholesale stations such as COPS Monitoring, Rapid Response and CMS monitor accounts on behalf of alarm dealers and integrators. They do not sell, install or contract with building owners; your local alarm contractor holds your account there. You benefit from the station's listing, but your contractor's own listing and license determine whether you can get a premises certificate.

Can a local alarm contractor give me UL-listed monitoring without owning a central station?

Yes. UL defines an "alarm service local company" that installs, tests and maintains the system and provides runner service while subcontracting monitoring to a UL-certified central station. If you need a certificate, check that the contractor itself appears in Product iQ, not only the station it uses.

What is UL 827, and what do CPVX and UUFX mean?

UL 827 is the Standard for Central-Station Alarm Services, covering the facility, staffing, redundancy and signal handling of a monitoring station. CPVX is UL's category for Central Station Burglar Alarm Systems; UUFX is Central Station Protective Signaling Services, the central station fire alarm category. Both are full-service categories whose listed companies can issue premises certificates.

How do I verify that a monitoring company is really UL listed?

Search the company's legal name in UL Product iQ at productiq.ulprospector.com, confirm the category code (CPVX or UUFX) and listed location match your requirement, and ask for the certificate number and issuing company if you need a premises certificate. A listing in the wrong category does not satisfy the requirement.

My insurer says I need a UL certificate. What exactly do I ask the alarm company for?

Ask for a Protected Property Alarm System Certificate issued for your address, in the category your insurer named (CPVX for burglar, UUFX for fire), with the extent of protection and any line-security grade stated. Ask which listed company issues it, when it expires, who performs the annual inspection and what it adds to the monthly rate.

Does UL-listed monitoring cost more per month than standard monitoring?

Seldom by itself; in the quotes we see, the station's listing is a property of the facility rather than a separately billed item. The cost comes from what a premises certificate requires: higher-grade equipment, supervised dual-path communication, runner service and annual inspection. Expect certificated service toward the top of our published ranges of $30 to $75 a month for intrusion and $60 to $150 with fire.

What is the difference between UL listing and TMA Five Diamond?

UL listing is a third-party audit of the monitoring facility and service against UL 827. TMA Five Diamond is The Monitoring Association's annual designation for centers whose operators have all completed TMA training and that meet its operational standards. It is a strong quality signal, but it does not satisfy a requirement written as "UL listed" and cannot produce a premises certificate.

Do I need UL-listed monitoring for fire alarms as well as burglar alarms?

Fire monitoring requirements come from code rather than your insurer. UL describes central station fire alarm service as NFPA 72 elements delivered through a listed station, and where code requires monitoring, the fire marshal specifies the kind of supervising station accepted. Confirm the category (UUFX for central station service) with your authority having jurisdiction and price fire monitoring as its own line.

Get UL-compliant quotes you can compare line by line

We do not install or monitor anything, which is why we can show you both routes side by side. Submit one building profile through our quote request form, state the UL requirement your insurer or AHJ gave you, and we match you with licensed, insured contractors we have screened for state licensing, insurance certificates and central station credentials, including UL-listed stations and TMA Five Diamond. The quotes you receive name the central station each contractor uses and its listing, the monthly rate for intrusion and fire, the term and renewal clause, and who owns the panel and communicator, so you sign with someone who actually satisfies the requirement rather than someone who says "UL" in a sales call.
