BRK RM4 Relay Module for Smoke and Smart Interconnect

Relay module designed to activate auxiliary devices when an alarm is triggered. Works with smoke, heat, and carbon monoxide alarms featuring smart interconnect capability. The relay contacts activate whenever any interconnected alarm sounds and automatically deactivate seconds after the alarm stops. Operates on 120V AC power with Form-C contacts that switch between normally open and closed positions. Can be installed adjacent to an AC alarm or in a remote location. Must be mounted in a junction box. Ideal for integrating alarms with external notification systems, lighting, or other auxiliary equipment.
