Combination, CO/Smke Detector

This was a replacement unit for a similar original installation. These units have a 5 yr life expectancy and my original was at its 5 year anniversary. I had no maintenance problems during its life just battery replacements. Fortunately it was never called upon to alarm. Easy and convenient to install. With gas fired HVAC and gas cook stove I felt the need to add this protection.

Great product,great price,very quick shipping! 100% satisfied

Perfect, fast shipping. I would recommend

GCO1CN

Excellent alarm for propane use. We have never had a problem with it.

carbon monoxide

this product is really and all of our customer loved this detector.

Saved Our Lives!!!

We purchased several CO alarms with the explosive gas detector a while back, model GC01CN. Nice because it has a variety of mounting options, and battery backup. The other afternoon, one of the alarms went off....thought it was probably a low battery warning. Battery checked fine, but over a 70 rating on the CO alarm!!! Yes, we evacuated immediately Checked the gas stove, it was off, and I thought there was a low likelihood that the furnace was the source as it was less than 6 month old, and we have an electric hot water heater.... Well guess what, it WAS the new furnace!!! There was a malfunction in a gas valve...I was assured that it was covered under warranty not comforting, but what was comforting was the performance of our First Alert GC01CN alarm. Thank you very much.

bought as replacement of expired alarm. just plugged in one of the three purchased, and it worked. that does not always happen. have three working alarms of this model and have always been pleased with them before.

First Alert First Rate

I needed this in a room which has gas and potential carbon monoxide. This is my second such First Alert alarm. Hopefully, Ill never find out how well it works, but the first one held up fine until it reached its END as indicated on the screen.

Best on the market!

This First Alert Alarm is recommended by Consumer Reports--and I trust them!

Best on the market

According to Consumer Reports, this is the best detector available!

Excellent product

I am very happy with my purchase. The unit is a good complement to the smoke alarms in the house, giving me peace of mind that I will be alerted if there is a presence of explosive gas or carbon monoxide in my home.

Our alarms are good and we made a great purchase

Two functions!

i so appreciate that this Alarm monitors CO as well as explosive gases. the last thing that you want is a gas leak that you do not know about!

first alert

great product glad they make for more dangerous gases

First Alert Combo Alarm

Just recently installed the First Alert Combo alarm. So far, it seems to be working fine. It is summer, so there is little to no gas to detect at this point, though.

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.

Review

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