Product Description

Monitor your house for dangerous levels of methane, propane, and carbon monoxide with 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 alarm's 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.


Carbon monoxide (CO) is the leading cause of accidental poisoning deaths in America, yet many people don't know they are suffering from CO poisoning until its too late. Since symptoms of CO poisoning are like the flu, you might not even know you're in danger at first. That's why a carbon monoxide alarm is an excellent way to protect your family. It can detect the CO you can't see, smell or taste in the air.

The First Alert GCO1CN combination explosive gas and carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. It also detects natural gas, methane gas, and propane gas. Installation is as simple as plugging it in to any wall outlet or mounting it above an outlet and plugging in the higher line cord. Its easy-to-read large digital display gives you a clear readout of current hazard and levels. A peak level button alerts you to the highest level of explosive gas or carbon monoxide detected. The alarm includes a battery back-up giving you peace of mind in a power outage. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The unit monitors and alarms if carbon monoxide or explosive gas levels persist sounding a loud 85-decibel horn. A low battery signal alerts you to replace the 9-volt battery (included).
