Kidde 21031556 Detect Series Direct Wire Smoke Alarm with 10-Year Battery Backup and Interconnectable

Protect residents and assets with the Kidde Residential Detect Series direct-wire smoke alarm (model 21031556), engineered for reliable, low-maintenance fire detection. This Kidde hardwired smoke detector combines a photoelectric sensor—reducing false alarms from cooking—with 120V AC power and a sealed 10-year lithium battery backup so units remain operational through power interruptions without frequent battery service. When smoke is detected the alarm emits an 85 dB audible alert and a synchronized flashing red LED; because units are interconnectable, one activation triggers every connected alarm to sound, improving building-wide safety and monitoring. The discreet 5-inch design fits living rooms, bedrooms, hallways and common areas, and includes test/hush features to simplify maintenance for property managers and installers. Built to UL standards, the Detect Series integrates into your site’s fire safety and security plans and complements broader surveillance and monitoring systems. Upgrade your fire detection coverage now to enhance occupant protection and simplify ongoing maintenance.
