This CO alarm includes a battery backup to make sure it is monitoring your home at all times and uses high-tech electrochemical sensors to provide accurate carbon monoxide readings that will always keep you protected.

Plug-in to Peace of Mind

To prevent nuisance alarms from everyday activities, CO detectors are time-weighted alarms that are based on time and the concentration of CO levels. This unit will only sound an alarm if low levels of CO have been detected over a long period of time, but high or unhealthy levels of CO will immediately trigger an alarm.
