First Alert Battery-Powered Ionization/Photoelectric Dual Sensor Smoke Detector

The First Alert Dual-Sensor Smoke and Fire Alarm is designed to provide peace of mind. This fire detector offers comprehensive monitoring for smoke by using two different sensors. A single button silences the alarm and tests the unit, while a loud 85-decibel siren is designed to alert even the soundest of sleepers. The battery-powered design allows the fire detector to be installed easily.
