Featuring a low-profile， contemporary design， the First Alert Slim Battery-Operated Photoelectric Smoke Alarm provides the same protection as a standard smoke alarm while taking up only a fraction of the space. This slim smoke alarm uses an ultra-reliable photoelectric sensor to detect smoke from slow-burning， smoldering fires， and it features a patented smoke entry system that allows a direct path to the sensor for more reliable detection. The battery-operated smoke alarm requires no hardwiring for installation， making it an ideal solution for those who want to enhance fire safety without hiring an electrician. 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. Half as thick as a standard alarm， the smoke detector has a sleek， slim design that blends in seamlessly with most decor. 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.
