Peep,peep,peep! I knew it was time to replace our carbon monoxide detector. First Alert has always been a reliable device for both smoke and monoxide detectors. True to its reputation we purchased First Alert and feel secure. I highly recommend First Alert.

Easy to install the backup battery. The plug and detector can be separated a few feet, and the detector mounted on the wall if desired. No alarms so far thankfully.

I trust the First Alert brand to provide me peace of mind in knowing that this product will not fail. The last unit I bought reached the end of its life and notified me that it was time to replace it. This is definitely worth the investment.

I had an earlier model of this First Alert detector and was pleased with the simplicity of it so bought the same thing again. It is an inexpensive safety item to own. This is easy to test yourself.

This is a must have in the bedroom level along with a fire extinguisher in each kitchen.
The installation could not be easier because my carbon detector is plugged into an electrical receptacle.

I returned this item. It’s not really a plug in. It has to be mounted. Too much work for me.
