Customer Reviews For The Battery-Operated Carbon Monoxide Alarm

A battery powered carbon monoxide alarm requires zero electrical wiring and does not occupy a wall outlet. This allows you to install the carbon monoxide detector in optimal locations on walls or ceilings throughout your home, especially in hallways outside bedrooms or in rooms without accessible plug sockets.

The First Alert CO3-B01 Carbon Monoxide Detector utilizes an advanced electrochemical sensor to monitor air quality continuously. When dangerous carbon monoxide levels are detected, the unit triggers a loud 85 decibel warning siren designed to alert residents and wake sound sleepers throughout the house.

The First Alert CO3-B01 Carbon Monoxide Alarm features an easy access front loading battery compartment. You can swap out the standard alkaline batteries directly from the front panel without having to unscrew the entire detector from the wall or ceiling.

You can test this battery operated carbon monoxide detector by pressing the single test and silence button on the front of the unit. Pushing this button performs an internal electronic test of the circuitry, battery levels, and horn function to ensure full operational readiness.

The First Alert CO3-B01 Carbon Monoxide Detector provides reliable gas detection for up to seven years. When the internal electrochemical sensor reaches the end of its functional life, the unit sounds an automated end of life chirp to notify you that it is time to install a new replacement detector.
