Public Safety Communications Solutions in Arizona
Many Arizona buildings are required by fire code to have a public safety radio system, called an Emergency Responder Radio Communication System (ERRCS) or Emergency Responder Communication Enhancement System (ERCES). Arizona’s State Fire Code is based on the 2018 International Fire Code (IFC), and Section 510 sets the rules for in-building radio coverage. Cities like Phoenix, Chandler and Tucson adopt their own versions with local amendments, and the fire marshal enforces them.
Phoenix now follows the 2024 Phoenix Fire Code, which requires most new multi-story and larger commercial buildings to pass a radio coverage test. Buildings that fail need an ERRCS, and a Certificate of Radio Coverage Compliance must be submitted before a Certificate of Occupancy is issued. Across the Valley, systems that boost the Regional Wireless Cooperative (RWC) radio network also need

Advantages of ERRCS/ERCES Installation Through RFE Communications in Arizona
- Coverage testing first: We grid test your building to IFC Section 510 standards, so you know early whether a system is required.
- Built to your city’s code: We design to Arizona’s State Fire Code (2018 IFC), your city’s amendments in places like Phoenix and Chandler, and NFPA requirements.
- RWC and PCWIN approvals: We prepare your fire permit and your RWC Rebroadcast Authorization in the Valley, or coordinate with PCWIN in Tucson.
- Qualified to Arizona standards: We’re NICET-certified as the RWC requires, hold FCC GROL licenses, and are certified on ADRF, Comba and Westell equipment.
- Class A BDA systems: We install the Class A amplifiers required in jurisdictions like Chandler, with backup power and fire alarm panel monitoring.
- Inspection and CO support: We test after your building envelope is complete, meet with fire and RWC inspectors, and provide the Certificate of Radio Coverage Compliance Phoenix requires.
- Annual testing: Arizona fire codes require yearly ERRCS/ERCES testing. We handle the testing and the paperwork.
Certifications and Licensing in AZ
Arizona’s State Fire Code is based on the 2018 International Fire Code, and Section 510 sets the minimum qualifications for people who design, install and test ERRCS/ERCES systems. They need a valid FCC General Radiotelephone Operator License (GROL), plus in-building system training from an approved organization or the equipment manufacturer. RFE’s engineers hold the GROL and manufacturer certifications from ADRF, Comba and Westell, as well as NICET In-Building Public Safety Communications certification, which many Arizona jurisdictions, including Phoenix, now require. Every BDA we install is configured to meet FCC signal booster rules (47 CFR 90.219), and we coordinate with your local public safety radio network for approval to rebroadcast its signal.


ERCES & BDA Solutions in Arizona
When a fire marshal requires radio coverage for your building, RFE Communications manages the process from start to finish. We perform the grid test, design an ERRCS/ERCES and BDA system to your city’s fire code, prepare the permit and radio network approvals, and work with inspectors through final sign-off. A coverage test early in construction is the best way to avoid delays to your Certificate of Occupancy.
ERRCS Preventative Maintenance in AZ
In addition to our professional installation services, our skilled engineers offer annual system checks and ongoing remote monitoring. This proactive approach is crucial because environmental changes, such as new tower installations or shifts in wireless congestion, can compromise the coverage of a system that was initially fully code compliant. This situation could potentially jeopardize your location’s Certificate of Occupancy (CO) in Arizona.

F.A.Q.
We’ve answered some of the most common questions about Public Safety Communications solutions here, but if you don’t see your question, just ask and we’ll be in touch.
What is a Public Safety Communications System/ERRCS?
A Public Safety Communications System or Emergency Responder Radio Communication System (ERRCS) is a wireless communications system used by emergency services and first responders to communicate effectively in case of an emergency. These are typically installed on all newer businesses and large properties based on regulations and typically under the supervision of a county Fire Marshall.
Is an ERCES the same as an ERRCS?
Yes. ERRCS (Emergency Responder Radio Communication System) and ERCES (Emergency Responder Communication Enhancement System) are two names for the same thing: a system that boosts first responder radio signals inside a building. Fire codes and fire marshals use both terms, and RFE Communications designs, installs and tests both.
Am I required to have a Public Safety Communications System?
A Public Safety Communications System, or ERRCS, is required in almost all new commercial properties and many other locations due to codes that are becoming standardized more and more by the NFPA and ICC, such at the National Fire Code, International Fire Code, and International Building Code. To find out what codes your business will be required to comply with before construction contact your county Fire Mashall.
How does having a Public Safety Communications System help me?
By ensuring you will receive your building permit and that your business will comply with all building codes and regulations as well as ensuring the safety of your employees by facilitating communications between first responders in case of emergency.
What is typically included in a Public Safety Communications System
Depending on the size of the property, floors, stairwells, basements, and other factors your property may need anything from bi-directional repeaters, sources, and a series of antennas both inside and outside the property strategically located to maximize coverage.
