Product Description
The BRK RM4 is a professional-grade, 120-volt AC-powered accessory relay designed to seamlessly bridge residential life-safety systems with external auxiliary systems. Operating via a "Smart Interconnect" system, the RM4 interprets signals from compatible BRK and First Alert smoke, heat, and carbon monoxide (CO) alarms. When an interconnected alarm is triggered, the module instantly toggles its internal switches to activate or deactivate peripheral devices, effectively expanding a standard residential safety network into an automated, property-wide emergency response system.
Features
-
Form-C Dry Contacts: Features isolated Form-C contacts capable of switching back and forth between Normally Open (N.O.) and Normally Closed (N.C.) positions, affording complete design flexibility for both standard-on and standard-off auxiliary loops.
-
Smart Interconnect Capability: Specifically calibrated to distinguish and pass complex alarm communication signals down a single interconnect line, ensuring compatibility across multi-threat (Smoke and CO) systems.
-
Automatic Reset: Resets automatically as soon as the initiating alarm clears. The relay contacts remain active for the duration of the threat and seamlessly deactivate a few seconds after the alarms cease sounding.
-
Extensive System Interconnection: Supports a robust system architecture. Per National Fire Protection Association (NFPA) guidelines, a single interconnected network can support up to 18 compatible BRK/First Alert devices—consisting of a maximum of 12 smoke alarms paired with up to 6 RM4 relay modules.
