Kidde KI-IB4 Ki Series 4" Isolator Base, White

Ensure reliable fire detection and uninterrupted monitoring with the Kidde Commercial KI-IB4 4" Isolator Base. Designed for commercial security and fire alarm systems, this detector base features a built-in line fault isolator for Class A circuits that quickly isolates shorts and preserves power to unaffected devices — reducing nuisance outages and service calls. The KI-IB4 supports standard smoke detectors and includes a visual LED indicator for fast diagnostics. Installers benefit from room-side accessible wiring terminals that simplify connection and maintenance, while the shallow 1½" (38 mm) profile and white finish keep the base unobtrusive in ceiling-mounted and panel applications. Ideal for integration into surveillance, monitoring and fire alarm loops, the Kidde KI series base helps maintain system integrity and uptime in demanding environments. Add the KI-IB4 to your next commercial fire protection or security installation to improve resiliency and streamline upkeep.
