Featuring a slim, space-saving design, this First Alert battery-operated photoelectric smoke alarm uses an ultra-reliable photoelectric sensor to detect smoke from slow-burning, smoldering fires, and a patented smoke entry system with a direct path to the sensor for more reliable detection. This smoke alarm also features an escape light that can help you find your way in a power outage or other emergency. The lithium-ion battery provides continuous power for up to a decade, and the alarm requires no hardwiring for installation. The simple twist-lock mounting system installs easily onto a wall or ceiling, while the tamper-resistant locks help prevent removal of the battery to keep the alarm secure. A loud 85-decibel alarm sounds when smoke is detected, and a convenient test/silence button lets you easily check alarm function and mute false alarms.
