CO250B Basic Battery Operated Carbon Monoxide Alarm

Electrochemical Sensor Detects CO

The First Alert CO250B Battery-Operated Carbon Monoxide Alarm uses an advanced electrochemical CO sensor to detect elevated carbon monoxide levels from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage. When CO is detected, the carbon monoxide detector sounds a loud 85-decibel alarm to warn you of the threat. Carbon monoxide can’t be seen, smelled, or tasted in the air and is the leading cause of accidental poisoning deaths in America. By placing carbon monoxide detectors on every floor of your home and in each sleeping room, you can help protect your family from the danger of CO.

Two Silence Settings

The CO250B battery-operated carbon monoxide alarm features two silence options. The low-battery chirp can be silenced for up to eight hours, and the CO alarm itself can be silenced for several minutes.

Safe Detection for Residential and Commercial Spaces

An electrochemical sensor provides early carbon monoxide warning in homes, apartments, hotels, hospitals, and other spaces. An easy-to-use mounting bracket allows you to mount the battery-operated alarm to a wall or ceiling.

Convenient Battery Operation

The CO alarm uses a 9-volt battery for operation, helping provide continuous protection in the event of a power outage. The alarm is programmed to chirp about once a minute when the battery life gets low and includes a tamper-resistant battery cover locking pin to help prevent undesired battery removal.

Slim Design Matches Any Décor

With a sleek, low-profile design, this battery-operated carbon monoxide alarm detector complements most décor. The classic white casing easily blends in with walls and ceilings.
