The Kidde KC2-RB4 is a 4-inch relay base for the Kidde KC2 Series two-wire conventional smoke detectors. Specifically, it provides one Form C relay that changes state when the connected KC2 detector enters alarm. As a result, the relay can drive auxiliary equipment such as HVAC shutdown or door release.
In addition, the base includes a trim skirt that conceals the mounting tabs. Therefore, the finished installation looks clean on the ceiling.
