Plug-In Carbon Monoxide Detector with Battery Backup, 85 dB Alarm and End-of-Life Signal – First Alert CO605
This plug-in carbon monoxide detector uses an electrochemical sensor to monitor CO levels in a room and sounds a listed 85 dB alarm when elevated levels are detected. It plugs into a standard wall outlet, keeping installation simple without adding a separate mounting plate or display setup.
Battery backup keeps the alarm operating during a power outage. A single button tests the alarm and silences appropriate notifications, while a low-battery signal can be muted for up to eight hours. An end-of-life chirp indicates when replacement is due. Choose the one- or three-alarm package for the planned placement.
