First Alert® CO410A Battery-Operated Carbon Monoxide Alarm with Backlit Digital Display. This carbon monoxide detector uses an electrochemical carbon monoxide sensor. An easy-to-read backlit digital display allows a quick view of current and peak CO levels. This unit is powered by two replaceable AA batteries, offering peace of mind even during power outages. The First Alert® CO410A Battery-Operated Carbon Monoxide Alarm uses an advanced electrochemical CO sensor to detect elevated carbon monoxide levels. When CO is detected, the carbon monoxide detector sounds an alarm to warn you of the threat. Carbon monoxide can't be seen, smelled, or tasted in the air, and it is the leading cause of accidental poisoning deaths in North America. Placing carbon monoxide detectors on every floor of the home and in each sleeping room is an important way to protect your family from danger. When carbon monoxide levels rise, the carbon monoxide detector sounds an 85-decibel siren. A low-battery alarm alerts you when battery power is running low, and an end-of-life timer lets you know when the device should be replaced. A low battery signal mute quiets the low battery signal for up to eight hours. Each CO detector lasts approximately five years.
