The RM4 is designed to activate an auxiliary device when an alarm is initiated. The RM4 Relay is intended for use with BRK and First Alert Smoke, Heat and Carbon Monoxide Alarms. The relay contacts will activate whenever any interconnected alarm sounds. The relay contacts will automatically deactivate a few seconds after the alarm stops sounding. The RM4 may be wired next to an AC alarm or from a remote location. This relay must be installed in a junction box.

Interconnects smoke alarms, carbon monoxide alarms and heat alarms with:
Lights,Bells,Door Closers,Sirens,Exit Signals,Escape Lights,Exhaust Fans,Other Auxiliary Devices
