Be alerted to dangerous carbon monoxide leaks with the 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 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. Thanks to the unit's backlit LED display, it's easy to see the current CO concentrations in parts per million, as well as recent peak levels, and the threshold for dangerous levels. The easy-to-read display illuminates when a button is pressed or an alarm is triggered. A remote control can be used to quiet unwanted alarms.
