Emergency Responder Radio Coverage System (ERRCS / DAS / BDA)

Emergency Responder Radio Coverage Systems (ERRCS / DAS) in Los Angeles

Ensure reliable first-responder radio communication inside your building — installed and tested according to LAFD, LADBS, NFPA, and California Fire Code requirements.

At Volta Electrical & Fire, we design, install, test, and maintain Emergency Responder Radio Coverage Systems (ERRCS), also known as DAS (Distributed Antenna Systems) with BDA (Bi-Directional Amplifiers), to ensure firefighters and law enforcement have uninterrupted radio communication during emergencies.

What Is ERRCS / DAS and Why Your Building Needs It

ERRCS/DAS is a lifesaving public-safety system that strengthens first-responder radio signals inside your building. Many structures block radio signals due to:

Concrete walls
Underground levels
Elevator shafts
Thick structural steel
Energy-efficient Low-E glass

An ERRCS system ensures critical emergency radio communication works anywhere inside the building, especially in areas where lives depend on fast coordination.

Buildings in Los Angeles That Require ERRCS

Building may be required to install or upgrade ERRCS if it meets any of the following:

There are more than 3-stories above grade plane.
The total building area is 50,000 square feet or more.
The total basement area is 10,000 square feet or more
Any basement or level that extends 2 or more stories below grade plane.

Los Angeles uses specific requirements from LAFD, LADBS, NFPA 72, and NFPA 1225/2019 for ERRCS compliance.
