Advanced Electrochemical CO Sensor
The First Alert CO410 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 and ensure their safety.
Easy-to-Read Digital Display
Thanks to the battery-operated CO detector'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.
Comprehensive Warning Features
When carbon monoxide levels rise, the battery-operated carbon monoxide detector sounds an 85-decibel alarm. A low-battery alarm alerts you when battery power is running low, and an end-of-life warning lets you know when the detector should be replaced. A low battery signal mute quiets the low battery signal for up to eight hours.
Simple and Easy to Use
The First Alert CO410 Battery-Operated Carbon Monoxide Alarm with Digital Display 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 easy access battery door allows you to quickly install or remove batteries without having to dismount the detector. A single button silences the alarm and tests the CO detector.
