Hardwired Photoelectric Smoke Alarm with 10-Year Sealed Battery Backup

The Kidde 20SA10 Hardwired Smoke Alarm delivers next-level fire safety with cutting-edge photoelectric sensing technology and a 10-year sealed lithium backup battery. Designed to detect smoke up to 25% faster, it uses enhanced sensing technology to reduce false alarms caused by cooking and steam while maintaining quick, accurate detection when real smoke is present. Operating on 120V AC with a sealed 10-year battery backup, this alarm provides continuous protection during power outages and eliminates low-battery chirps. The interconnect feature allows up to 24 Kidde alarms to sound together for whole-home detection. Rigorously tested to meet UL 217 10th Edition and FCC standards, it features self-testing internal components, end-of-life notification, alarm memory, and a 10-year limited warranty.
