About This Product

The Kidde 4-Inch Compact Smoke Detector (10SDR) offers reliable, advanced fire safety for your home. Its enhanced sensing technology reduces false alarms often caused by cooking and delivers fast alerts to help give your family more time to respond. The compact 4-inch design is perfect for small spaces without sacrificing essential features. Powered by 2 AA alkaline batteries (included), the smoke detector continues to function during outages. The red LED blinks to indicate the alarm is operational, and flashes in sync with the 85-decibel alarm when smoke is detected. A test-hush button allows you to test battery operation and silence nuisance alarms. The device is self-testing and easy to install with the included twist-and-click mounting bracket.
