emergency responder radio communications system (ERRCS)

The emergency responder radio communications system (ERRCS), also known as Public Safety or First Responder DAS (Distributed Antenna System), has become a mandate in-building requirement for many municipalities around the State and Country. The network essentially re-transmits fire or police radio frequencies from outside a building, where the signal is presumably stronger, into a building where it is usually weaker or non-existent. These signals are imperative for first responders to be able to communicate with their peers outside of the building during an emergency.

What is PSERN and why do I have to provide a compatible system?

PSERN is the Puget Sound Emergency Radio Network, a voter-approved effort to replace our region’s aging emergency radio system with a modern, reliable network that provides greater coverage throughout King County.

When completed, the new system will be used by first responders — including police, fire and emergency medical personnel — in all 39 King County cities and throughout unincorporated King County.
