What is ERRC?
ERRC (Emergency Responder Radio Communications), also known by several other acronyms, such as “DAS” (Distributed Antenna Systems) and “BDA” or “BAS” (Bi-Directional Amplifier Systems), are radio systems that serve emergency responders with reliable communication from inside buildings. These systems consist of a radio “repeater” that collects a radio signal on the outside of a building and re-broadcasts it with a stronger signal inside the building.
The purpose of this stronger indoor signal is to ensure emergency personnel will have reliable radio communication, in real-time, from inside the building. After the events on 9/11 resulted in the loss of so many firefighters due to poor communication, the International Fire Code was updated to require these systems to be installed in all buildings where connectivity is an issue.
ATG Delivers Complete ERRC Solutions
ATG is a reliable source of guidance as owners, developers, and contractors work through the ERRC evaluation process. We will help you determine whether a system is needed, establish an integrated solution that will minimize cost exposure, and install the proper components at the right time during the construction schedule.


Life Safety
In addition to ERRC, ATG offers a suite of additional Life Safety solutions, adding additional layers of safety and security to all building occupants. Everything from Nurse Call to Emergency Notification Systems can be integrated into the total building solution.
Keeping You in Compliance
As buildings increase in size and efficiency, “green” technology such as, low-E glass, is preventing more and more radio communications. This has resulted in recent enforcement of ERRC fire codes in many areas. More and more jurisdictions are requiring an ERRC signal test result before issuing a CO or Certificate of Occupancy.
If an ERRC signal test determines that a radio amplifier system is needed, a licensed contractor must get approval for the system design, install the system, and prove the test results of a working system to the AHJ (Authority Having Jurisdiction).
