About This Product
This 10-year battery smoke detector, model 20SD10, features enhanced sensing technology designed to reduce nuisance alarms commonly caused by cooking while providing fast smoke alerts. Its compact 5 in. design works well in bedrooms, hallways, kitchens, living rooms, and other residential areas. A built-in lithium battery provides long-term power, while a loud 85-decibel alarm and flashing red LED help signal detected smoke. The unit also includes a test/hush button, automatic self-testing, status indicator lights, and a twist-and-click mounting bracket for simple installation. An end-of-life alert indicates when the detector reaches the end of its 10-year service period.
