The First Alert 10-Year Sealed Battery Photoelectric Smoke Alarm with Escape Light packs premium smoke detection capabilities into a sleek， compact design. For those who want a reliable detection system without hiring an electrician or worrying about hardwiring， this battery-operated smoke detector is an ideal solution. The detector uses a photoelectric sensor to detect smoke from smoldering fires while keeping false alarms to a minimum. A patented smoke entry system allows for a direct path to the photoelectric smoke sensor， helping ensure reliable detection. The alarm also comes equipped with an ultra-bright LED escape light， which helps illuminate an evacuation path during emergencies. This stylish smoke detector is sleekly designed to take up a fraction of the space of traditional smoke alarms， and it can be mounted unobtrusively on a wall or ceiling. A loud alarm sounds when smoke is detected， and a convenient test/silence button lets you easily check whether your alarm is functioning and mute false alarms.
