First Alert Plug-in Natural Gas, Propane and Carbon Monoxide Detector

The First Alert GCO1CN combination explosive gas and carbon monoxide alarm with backlit digital display. This explosive gas and CO alarm detects the presence of combustible gases propane and methane and alerts you with a loud 85-decibel alarm. It also comes equipped with an electrochemical CO sensor that accurately detects carbon monoxide leaks from faulty fuel-burning appliances, blocked chimneys, and a variety of other sources. Designed for easy setup, this explosive gas and CO detector plugs into any AC outlet with no additional mounting hardware needed. The alarm can 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. The backlit digital display shows current and peak levels, allowing you to easily review the alarms readings. For added safety, a backup battery helps keep the alarm functioning even in the event of a power outage. And thanks to a convenient test/silence button, you can easily check whether your alarm is functioning properly and mute false alarms.
