First Alert GCO1CN Combination Explosive Gas and Carbon Monoxide Alarm with Backlit Digital Display. Featuring a backlit digital display, this explosive gas and CO detector plugs into any AC outlet with no additional mounting hardware needed.
Detects Dangerous Levels of CO and Explosive Gases
Designed to promote peace of mind and household safety, the GCO1CN Combination Explosive Gas and Carbon Monoxide Alarm accurately senses the presence of methane and propane. It also features an advanced electrochemical CO sensor that detects carbon monoxide leaks from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage. When the alarm detects a threat, it alerts you with a loud 85-decibel alarm.
Backlit Display for Reviewing Readings
Equipped with a backlit digital display, the GCO1CN Combination Explosive Gas and Carbon Monoxide Alarm takes the hassle out of monitoring CO and explosive gas levels in your home. The display gives you a clear readout of current and peak levels, allowing you to discern patterns that indicate potential leaks from an appliance, a generator, or other source.
Plugs into Any AC Outlet for Effortless Setup
This alarm is easy to set up and doesn't require any wiring or the help of an electrician. The compact, low-profile unit plugs cleanly into an AC wall outlet without obstructing other sockets and comes with a line cord for versatile placement options. The alarm also features a 9-volt backup battery to help ensure continued operation in the event of a power outage. A pivoting, easy-to-access battery drawer allows you to replace the battery without dismounting the alarm.
Easy to Operate and TestFor added convenience, the alarm can be configured to work with almost any standard household remote control (not included), so you can remotely silence false alarms. A one-touch silence/test button makes it easy to test the detector or mute it during a false alarm. And thanks to the end-of-life timer, you can know exactly when it is time to replace your alarm.

Good that unit can be mounted several feet from outlet with extendable cord. Plugging unit directly into outlet not a good option as size is rather large.

Purchased same unit a few years ago. Needed two more for another home. Simple install and testing.

We have a fireplace in the living room that is very near our bedroom. Being able to just plug the unit into an outlet in the short hallway between our living room and bedroom was a real plus. The ability to have to unit somewhat remote to an A.C. outlet was a plus, but in our case, un-needed.

The first alert detector provides comfort in knowing our home is safer. It is aesthetically pleasing and simple to install. We just plugged it in.

I am pleased with the alarm but disappointed that I did not get the 20% off which came after I had just received the product. I got a 10%. But everyone has helped me understand about this product before purchasing it and with the smoke detectors in my home which I never got the booklet on them and cannot print them making it difficult to go up and down the ladder to read the computer specs about the smoke detectors . I did get the one I ordered so I am guessing the builder did not supply me one. I have brought this up in our development as some houses are older and mine is new. I would like to thank all the Customer service people that answered and guided me how to operate it and test them. Merry Christmas & Happy New Year.

The First Alert combo gas/CO alarm has been a fixture in our home for several years. Our latest purchase is a replacement for the same model that recently passed its recommended replacement date.
