Kidde SM120X Smoke Alarm Relay Module
The Kidde SM120X is designed to be used as part of a fire detection system with smoke detectors. It can be used to activate auxiliary warning devices such as external bells and sirens, hallway or stairway lighting.
This relay will only activate when it receives a smoke signal from an interconnect Smoke Alarm. Use this smoke alarm relay to add security to the fire safety plan for your home, work, or other place of residence.
