The BRK RM4 Relay Module is a 120V AC-powered relay that switches an auxiliary device when a connected BRK alarm goes off. It suits installers and homeowners who want a smoke or CO alarm to trigger something else, and it works with BRK Smoke and Heat Alarms and Smart Interconnect BRK CO alarms. Its Form-C contacts let you choose between normally open and normally closed wiring.
