Kidde 900-0280CA

The Kidde 900-0280CA provides continuous protection against the invisible threat of carbon monoxide (CO). Powered by standard 120V AC household power with a built-in 10-year sealed lithium battery backup, this carbon monoxide alarm continues monitoring even during electrical outages—without ever requiring battery replacement during its service life.

Its advanced electrochemical sensing technology continuously monitors carbon monoxide levels while the digital display shows real-time CO concentrations in parts per million (PPM). The display automatically adjusts brightness in darker environments for comfortable nighttime viewing.

The built-in Peak Level Memory stores the highest CO concentration detected since the last reset, providing valuable information about previous carbon monoxide events.
