Editorial Review
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 CO400 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. The permanent sensor lasts up to five years. It is powered by two AA replaceable alkaline batteries giving you peace of mind even during power outages. The test/silence button both silences the alarm and allows you to test its functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. No installation is required and the attractive design allows the unit to be placed anywhere you need it. It includes an optional wall mount with no outlet required. An audible and visual low battery signal alerts you to replace the battery. Pull down action chart has convenient guide on what to do if an alarm sounds. 5 year limited warranty. UL listed. --Bree Norlander

Haven't had to use it yet. It was delivered on time and packaged well.
I didn't have any problems with the transaction at all. I got it to use in my daughters car because she thought she may have a leak, due to the fact that whenever she drove, she became very tired. I guess if the alarm goes off, she will surely wake up, with as loud as they are!!
A must have!

When we built our home, I asked the contractor to make sure we had dual smoke - CO detectors/alarms. Recently, friends of ours lost their baby to CO poisoning while visiting relatives. Despite the devastation, they began to wage war on the lack of CO detectors in homes. That's when we noticed we only had smoke detectors in our home. No CO!
We purchased 5 of these; one for each bedroom, the main room, and an elderly neighbor. Install was painless. It does, however, need to be mounted on a wall, not a ceiling, so we chose a spot over each bedroom door.
Of course, so far we don't know if they work, but the piece of mind is enormous. More people die of CO poisoning than from fire. Why aren't these required to pass inspection? Please, check your equipment. If you don't have a CO detector, get one, two, etc. The price is right.
