Kidde SM120X Smoke Relay Module

The Kidde SM120X is a relay module designed to interconnect Kidde smoke alarms with external devices such as door holders, HVAC shutoffs, and building automation systems. When any interconnected smoke alarm triggers, the SM120X closes its relay output, activating the connected device — enabling coordinated, code-compliant fire response across a facility.
