The First Alert GCO1CN Combination Explosive Gas and Carbon Monoxide Alarm with Backlit Digital Display offers reliable detection of three common household threats: methane, propane, and carbon monoxide. Built for easy operation, this detector plugs easily into any AC outlet with no additional mounting hardware needed. A backlit display allows you to review the CO detector's readings, while a single button lets you test and mute the alarm with ease. The alarm can also be configured to work with almost any standard household remote control (not included), so you can remotely silence nuisance alarms with the push of a button. Features battery back-up in case of power outage, battery included. Battery life varies according to use and application.
Plug-in CO (carbon monoxide) alarm featuring battery back-up and backlit digital display. Uses an electrochemical carbon monoxide sensor, the most accurate CO detection technology available, to detect the CO you can't see, smell, or taste in the air. Easy-to-read backlit digital display allows a quick view of current and peak CO levels. Plugs into any wall outlet and includes a battery back-up for detection even during power outages. EZ access battery door allows you to change batteries without having to dismount the alarm. Battery life varies according to use and application. An 85-decibel horn sounds if carbon monoxide levels are too high, and a test/silence button silences the alarm and allows you to test its functionality. Meets UL2034 standards.
