First Alert Battery-Powered Photoelectric Smoke Fire Detector

Combining premium smoke detection with a sleek compact design the First Alert Micro Photoelectric Smoke Alarm with 10-Year Battery delivers the same advanced protection as a traditional alarm while taking up only a fraction of the space. This smoke detector uses an ultra-reliable photoelectric sensor to detect smoke from smoldering fires while keeping false alarms to a minimum. Much smaller than an ordinary smoke detector this unit is manufactured using 52 percent less resin and 76 percent less plastic than a standard alarm. The Smart Clip mounting system allows you to effortlessly install the detector on a wall or ceiling. A loud 85-decibel siren sounds if smoke is detected and a convenient test/silence button lets you easily check alarm function and mute false alarms.
