Description
The First Alert Hardwired Combination Smoke and Carbon Monoxide Alarm detects both carbon monoxide and smoke in a single device. It is designed for hardwired installation but features a 10-year battery backup that allows the unit to function in the event of a power outage. The CO smoke detector can be connected to other compatible BRK or First Alert CO smoke detectors within a single-family residence. A single button silences or tests the unit.
