• Electrochemical carbon monoxide sensor the most accurate sensor available as compared to other sensing technologies
• Simple and Easy to Use
• Single button test/silence
• Two silence features can silence the low battery chirp for up to eight hours or temporarily silence an unwanted nuisance alarm
• End of life signal provides audible notification alarms needs to be replaced
• Basic Plug-In Carbon Monoxide Alarm
• When carbon monoxide levels rise, the carbon monoxide detector sounds an 85-decibel siren that is designed to wake even the soundest of sleepers
• 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 hr
• Each CO detector lasts approximately five years
