Kidde 20SAR Smoke Detector – Hardwired with AA Battery Backup, Interconnectable, 85 dB Alarm

Safeguard your living spaces with the Kidde 20SAR Smoke Detector. This hardwired unit runs on 120V AC and includes two AA alkaline batteries for backup, helping maintain continuous smoke detection during power outages.
