Use this relay module to connect your interconnected hardwired and household AC-powered Kidde smoke alarms to your Konnected Alarm Panel. This device wires into the 3-wire hot (black) / neutral (white) / interconnect (red) circuit and provides a Normally Open (NO) and Normally Closed (NC) dry-contact output that can be connected to any input zone on the Konnected Alarm Panel. The relay activates when the smoke alarm interconnect is triggered, allowing you to integrate your household wired smoke alarms into your smart home automations and routines.
