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.
Advanced Electrochemical CO Sensor
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.
Easy-to-Read Digital Display
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 (remote control sold separately).
Comprehensive Warning Featurese
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.
Simple and Easy to Use
The First Alert CO410A Carbon Monoxide Alarm is easy to set up. Simply insert the two included AA batteries, and the CO detector will start to monitor your space for carbon monoxide. An EZ access battery door allows you to quickly install or remove batteries without having to dismount the alarm. A single button silences the alarm and tests the CO detector.
