Secure your home or facility against the threat of carbon monoxide leaks with the BRK CO250B Carbon Monoxide Alarm. Equipped with an electrochemical carbon monoxide sensor, a test switch, an 85-decibel horn, and a red LED power indicator, this carbon monoxide detector warns you to the presence of carbon monoxide.

Electrochemical Sensor Reliably Detects CO

The First Alert CO250B 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 carbon monoxide.

Two Silence Settings

The CO250B carbon monoxide detector alarm features two silence options. The low-battery chirp can be silenced for up to eight hours, and the 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 alarm to a wall or ceiling.

Convenient Battery Operation

The carbon monoxide alarm uses a 9-volt carbon monoxide detector battery for operation, helping provide continuous protection in the event of a power outage. The device is programmed to chirp about once a minute when the battery begins to die 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 CO monitor complements most décor. The classic white casing easily blends in with walls and ceilings.
