The First Alert FG250A Smoke Alarm was specifically designed for residential and institutional applications including sleeping rooms of hospitals, hotels, motels, dormitories, and other multifamily dwellings. The compact, low profile design of this alarm complements any decor. Battery installation and removal can occur while the smoke detector is mounted to the ceiling or wall via the hinged cover. When voltage drops to a pre-set warning level, the horn will "chirp" approximately once per minute to indicate a fresh battery is needed. To ensure the battery is always replaced properly, the cover is designed to resist closing when the battery is missing. Designed for wall or ceiling mounting, this smoke alarm includes mounting anchors and screws. The First Alert FG250A Battery Powered Smoke Alarm comes with a 10 year limited warranty.
Ionization Sensor Reliably Detects Flaming Fires
The First Alert Hardwired Smoke Alarm with Battery Backup comes equipped with an ionization sensor to provide the earliest possible warning of a fast-flaming fire. The sensor is optimized to detect flaming fires, such as those caused by paper, kitchen grease, and other fast-combusting materials.
