First Alert PR710E Slim Smoke Detector with Photoelectric Sensor and LED Escape Light

Featuring a low-profile design, the First Alert PR710E Slim Photoelectric Smoke Alarm provides the same protection as a standard smoke alarm in a fraction of the space. This slim, 10-year smoke alarm uses an ultra-reliable photoelectric sensor to detect smoke from slow-burning, smoldering fire, and features a patented smoke entry system that allows a direct path to the sensor for more reliable detection. Plus, this easy-install alarm features an LED escape light that illuminates when the alarm sounds to help guide you to safety. 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 smoke alarm battery to keep it 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.
