The First Alert CO400 Carbon Monoxide Alarm utilizes an electrochemical carbon monoxide sensor to detect carbon monoxide. This carbon monoxide detector is battery operated, making it portable and easy to use, even in the event of a power outage. When carbon monoxide levels become elevated, a loud 85-decibel alarm alerts you to the threat.
The BRK CO5120BN hardwire carbon monoxide alarm detects dangerous CO gas and allows you peace of mind with its battery backup. Carbon monoxide (CO) is a colorless, odorless, deadly gas. It can be emitted by sources including gas or oil furnaces, gas clothes dryers, water heaters, fireplaces, wood stoves, charcoal grills, gas ranges, and space heaters. A clogged chimney, improper venting, and attached garages can also cause carbon monoxide accumulation. According to the Consumer Product Safety Commission (CPSC), at least one CO alarm should be installed near a home's sleeping area. This BRK alarm is perfect for bedrooms, as well as hallways, and basements. *
