The New Public Safety Standard

Public safety in-building wireless communication systems are required in commercial buildings to ensure emergency responders have undisrupted connectivity anywhere on premises including critical coverage areas like fire command rooms, exit stairwells, elevator lobbies, basements, and exit passageways.

This guideline can help you understand what is UL 2524, why it is important, and how it is used.

Where Does UL 2524 Come From?

As the global safety science leader, UL helps companies to demonstrate safety, enhance sustainability, strengthen security, deliver quality, manage risk and achieve regulatory compliance.
They are one of several companies approved to perform safety testing by the U.S. federal agency, and the Occupational Safety and Health Administration (OSHA). They put safety science to work to help create a safer, more secure, and sustainable world.

What is UL 2524 and What Does it Cover?

UL 2524 is a standard proposed by Underwriters Laboratories for In-building 2-Way Emergency Radio Communication Enhancement Systems (ERCES). It represents the most rigorous set of standards to ensure emergency responders can communicate with each other in and around commercial buildings. UL 2524 includes additional critical safety and performance requirements not found in UL 60950/UL 62368. These requirements were adopted to align with similar requirements that have been utilized for fire alarm systems and which the fire alarm industry has found beneficial.

It does not cover passive RF components which are defined in the standard as any RF device that does not have an active electronic component, and instead, requires external power. This includes antennas, splitters, couplers, coaxial cables,s, and connectors.

UL 2524 second edition covers products including repeater, transmitter, receiver, signal booster components, remote annunciators and operational consoles, power supply, and battery charging system components. These technologies are meant to be deployed in accordance with the following Model Building and Installation Codes: NFPA 1, NFPA 72,  NFPA 101, NFPA 1221, and the International Fire Code (IFC).

The NFPA, and IFC

The National Fire Protection Association (NFPA) is a global self-funded nonprofit organization, established in 1896, devoted to eliminating death, injury, property, and economic loss due to fire, electrical and related hazards.

The International Code Council is the leading global source of model codes, standards, and building safety solutions that include product evaluation, accreditation, technology,  training, and certification.
The ICC’s International Fire Codes (IFC) are used to ensure safe, portable, and sustainable communities and buildings worldwide.

Why is the UL 2524 Standard Important?

UL 2524 is becoming a common requirement for ERCES and building owners will follow the UL 2524 Standard in order to receive their certificate of occupancy as the standard will rapidly be enforced by the authority having jurisdiction (AHJ) across the country. In fact, NFPA 1225 section 18.12.1.3 and IFC 2021, section 510.4 of the national model fire code both require system components to be listed and labeled in accordance with UL 2524 Certified products.

UL 2524 listing will not only make it easier to select an ERCES that’s compliant with AHJ-enforced codes, it will also make it easier for AHJs to enforce wireless product code testing and approval due to its UL 2524 certified mark and corresponding QR code.

UL Smart Mark™

Enhanced UL Listed/Certification Mark for UL 2524, Second Edition: Simply put, if an ERCES product has this marking then it is a UL Listed/Certified product by UL. AHJs can scan the QR code on the enhanced UL Smart Mark to receive complete details about the certification.

Misleading Phrases

All building owners will soon need to install a UL 2524 listed/certified product in new buildings. Unfortunately, there are many different terms thrown about when referencing  UL 2524 and it’s important to separate fact from fiction.

• UL 2524 Classified
  Passed some of the UL standards (i.e. only the fire and shock safety standards of the UL 2524), which is performed by a third-party nationally recognized testing facility.

• Conforms to UL 2524
  This does not indicate the passing of any testing. This will not meet AHJ requirements in most states and counties.

• Compliant to/with UL 2524
  The product believes it adheres to the standards laid out in UL 2524 but has not officially passed the testing or received the mark. This will not meet AHJ requirements in most states and counties.
