Product description

Style:Alkaline Battery - Frustration Free

The First Alert SA320CN Dual-Sensor Smoke and Fire Alarm is an advanced smoke detector that uses ionization and photoelectric sensors to provide early warning of both smoldering and flaming fires. It also features intelligent sensing technology to reduce false alarms from household triggers like cooking smoke or shower steam. The battery-powered fire detector installs quickly and easily, with no wiring or electrician required. A loud 85-decibel siren is designed to alert even the soundest of sleepers, and a single button silences and tests the fire detector.
