Emergency Responder Radio Communication Systems (ERRCS) in LA County

Emergency Responder Radio Communication Systems (ERRCS) in LA County

Keep Your Building Compliant. Keep People Safe.

When every second counts in an emergency, reliable communication can save lives. That’s why Emergency Responder Radio Communication Systems (ERRCS) are critical in modern building safety—and often required by law. These systems ensure that first responders, like police, fire, and EMS, can maintain clear radio communication inside your building during emergencies.

At Signal Alarm & Electric, we design and install ERRCS solutions that meet strict LA County code requirements and help protect both lives and property.

What Is an ERRCS?

An ERRCS is a specialized system that improves two-way radio coverage inside buildings where emergency responders might otherwise lose signal—places like stairwells, basements, elevator shafts, or areas constructed with signal-blocking materials like concrete and steel.

Whether it’s a fire, medical emergency, or security incident, responders must be able to communicate without interruption, making an ERRCS invaluable to your business.

Why Is ERRCS Installation Important?

  • Reliable Communication in Emergencies
    In emergencies, ERRCS eliminates dead zones that could cause a poor signal; delays in response times and avoids dangerous communication gaps
  • Compliance with Los Angeles Codes and Regulations
    LA County requires ERRCS systems in large or complex buildings. Compliance is typically based on NFPA and IFC standards, and enforced through local building and fire departments.
  • Public and First Responder Safety
    Emergency Responder Radio Communication Systems help protect the lives of those in the building and the emergency teams who respond when seconds matter most.

How Does an ERRCS Work?

An ERRCS consists of several components working together to bring external radio signals indoors:

  • Donor Antenna
    Captures the public safety radio signal from outside the building.
  • Bi-Directional Amplifier (BDA)
    Strengthens the incoming signal and rebroadcasts it throughout the building.
  • Distributed Antenna System (DAS)
    A network of antennas placed strategically throughout the building to ensure full coverage in all areas.
  • Backup Power
    Keeps the system running even during power outages.
