Kidde KC2-RB4 2-Wire 4" Detector Mounting Base with Relay Trim Skirt, White

Deliver dependable relay control where it matters most. The Kidde Commercial KC2-RB4 2-wire 4-inch detector mounting base is designed to give contractors and facilities managers a robust, code-ready platform for heat detector installations in commercial security and fire monitoring systems. Its supervised relay ensures the relay stays seated and signals any tampering or fault, reducing nuisance calls and maintenance time. The dry contact is rated for 1 A at 30 VDC, providing pilot-duty switching for external annunciators, fans, or control circuits. Built for integration, the KC2-RB4 can be programmed as a control relay at the panel for flexible automation and surveillance applications, though it does not support the GSA-LED remote LED. With FM Approval, cULus listing and California State Fire Marshal recognition, you get a compliant solution that streamlines inspections and deployments. Ideal for commercial fire alarm, security monitoring and building automation projects—specify the KC2-RB4 detector base when you need reliable relay supervision and easy system integration.
