Product Overview

Protect your family with the Kidde Firex Carbon Monoxide, Propane, Natural and Explosive Gas Detector, Hardwired with Battery Backup. The easy to install electrochemical Kidde Firex Carbon Monoxide, Propane, Natural and Explosive Gas Detector, operates by plugging the carbon monoxide alarm into a typical wall outlet. A 9-volt alkaline battery provides backup during power outages. Using electrochemical sensor technology, the Kidde Firex Carbon Monoxide, Propane, Natural and Explosive Gas Detector alerts to poisonous, invisible, combustible gases. The Kidde Firex Carbon Monoxide, Propane, Natural and Explosive Gas Detector has 3 LED lights that indicate: power connection, if the alarm senses combustion, fire, or smoke, or if the alarm is activated. The display will have a red dot in the lower, right corner that will blink to indicate normal operation. The gas alarm includes a test button that will electronically simulate the presence of CO or gas when pushed. When the unit detects carbon monoxide the alarm pattern will be 4 quick beeps and show in the display the carbon monoxide concentration in Parts Per Million. When the unit detects gas, the word "GAS" will be displayed and an alarm will sound. UL Certified with a 5-year limited warranty. Meets requirements of UL 2034.

Unreliable
I used this in an apartment for 2 years without issue. I moved and stored it in sealed bin, without the battery installed, in sealed bubble wrap. I tried to use this in my new apt and now it beeps every 30 seconds with an L6 code even though it now has a new battery and has been "reset". 4 year old piece of junk.

    My first Kidde Plug-In Carbon Monoxide and Explosive Gas Detector with 9V Battery Backup and Digital Display lasted almost 8 years and comes with a 5 year warranty. This is my 2nd unit. I like it since it not only detects carbon monoxide but also propane and natural gas which many others do not. I also like that it can operate using AC power or 9v battery. It can also be mounted on a wall. I highly recommend and hope it will still be available when this one reaches end-of-life in 8 or 9 years. Well worth the money for peace of mind and safety features.

    Product meets all expectations except color. All photos show detector in white. Store only offered in gray. Still appears to function well, just less visually appealing.

    I only gave a five-star review despite the fact that there is no easy practical way to test this device for actual function using real gas or CO. Set-up was easy and it appears to be functioning correctly. It is installed in the home of an elderly couple who have just recently converted to an LGP kitchen range. Hopefully this detector will never be needed, but it does provide additional peace of mind protection should a problem arise with the range or they accidentally leave a vehicle running in the attached garage. Big plus is that the alarm siren is loud and at a pitch even people with considerable hearing damage as myself can hear easily.

    Great Product!`
    This was bought to replace an ancient Nighthawk that we bought back in the late 90s early 2000s. The explosive gas detection helped with peace of mind when we bought and moved an old farm house and were not sure the old appliances were safe. Great device!

    A good value and it works
    I purchased this unit after my wife woke me up and told me she thought she smelled gas. After being up the rest of the night assuring her she didn’t I drove to Home Depot and picked up this combination Gas/Carbon Monoxide detector unit. I tested it with an open gas valve and it works well. The alarm emits a very loud piercing blast that is sure to wake up even the soundest sleeper. Having an alkaline 9 volt battery (included) backup; it can be unplugged and moved from room to room for testing. You can plug it right into a 110 volt outlet or slide out a built in stand and sit it on the counter. I have used a Nighthawk Carbon Monoxide detector for several years with no problems. In my opinion this combination unit is a very small price to pay for a good night of sleep.
