Emergency Responder Radio Communications Systems (ERRCS)

Johnson Controls partners with Westell for emergency in-building radio coverage enhancement


Also known as BDA/DAS, the ERRCS is a system in a building that receives external Public Safety radio signals and retransmits them within the building ensure penetration in all areas including stairwells, elevators, basements, and other heavily shielded areas.

The ERCCS supports Land Mobile (Handheld) radios used by First Responders inside buildings during emergencies. ERRCS guidelines are found in by NFPA 72, 2016 edition and IFC 2019. Many jurisdictions now mandate public safety radio coverage as a condition for a Certificate of Occupancy in new construction or retrofits. 

The ECCRS is made up of a donor antenna that receives external radio signals from the local emergency responder radio tower, a bi-directional amplifier/repeater that boost the radio signal, a coaxial cable or fiber medium that distributes the radio signal throughout the building, and coverage antennas that transmit and receive radio signals within the building for reception by Land Mobile (handheld) radios used by emergency responders.
