Definition
ERRCS (Emergency Responder Radio Coverage System), also known as ERCES or Public Safety DAS, is the code-mandated solution for ensuring police, fire, and EMS personnel can communicate via radio inside buildings. Modern construction materials often block radio signals, creating dangerous communication dead zones. ERRCS uses bi-directional amplifiers (BDAs) and distributed antenna systems (DAS) to capture outdoor signals, amplify them, and redistribute them throughout the building while also boosting signals from portable radios back to outdoor infrastructure.
How It Relates to ERRCS Compliance
ERRCS is the central compliance requirement when a building fails to meet first responder radio coverage thresholds. It is the system owners install, test, and maintain to satisfy adopted fire code requirements and protect certificate of occupancy timelines.
