Kidde 20SAR Hardwired Smoke Detector – 4 Pack, AA Battery Backup & Interconnect

Elevate home fire safety with the Kidde 20SAR four-pack

Protect your living spaces with a dependable, interconnected smoke detection solution. The Kidde 20SAR hardwired detectors run on 120V AC and include two AA alkaline batteries per unit, providing backup during power outages. The sleek 5-inch housing blends neatly with ceilings in living rooms, hallways, kitchens, and bedrooms, while LED indicators and a clear 85-decibel alarm deliver immediate cues when smoke is detected.

Designed to minimize false alarms yet enhance responsiveness, these detectors feature enhanced sensing technology that helps distinguish everyday cooking scents from real smoke. When any detector triggers, the interconnect feature ensures all linked alarms sound together, giving your family more time to respond. A simple twist-and-click mounting bracket makes installation straightforward, and a weekly button test helps you confirm operation between changes in the home environment.

Key indicators appear at a glance: green for normal operation, amber for an operating error, and red when smoke is detected. The combination of self-testing capability, a robust 10-year warranty, and adherence to UL 217 9th Edition and FCC standards reflects a practical approach to reliable home safety.
