Amazon.com Product Description

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

5.0 out of 5 stars CO ALARM - everyone w/gas should have one, February 26, 2009
Amazon Verified Purchase( What's this?)
This review is from: First Alert CO400 Battery Powered Carbon Monoxide Alarm (Tools & Home Improvement)
We tested it on the truck's exhaust and it went off at about 60 ppm according to our digital CO Meter.
Which proves it works to Govenment Standards. This model does what it is supposed to do, the more expensive models just have more features that you probably will not notice on an everyday basis anyway.

This is the least expensive model we have seen that functions, so we hope at this price everyone should have one in their home and garage.

Please replace batteries regularly......

1.0 out of 5 stars I've had 2 of these now and both were defective, December 22, 2010

Bought this in November. Put it up and within days it's "chirping" 3 times per minute which means (according to the device) that it is malfunctioning and needs to be replaced. Amazon was awesome and sent out another one right away. Same exact problem. I'll be returning the second one and choosing another alarm.

5.0 out of 5 stars A must have!, March 14, 2008

This review is from: First Alert CO400 Battery Powered Carbon Monoxide Alarm (Tools & Home Improvement)
We purchased 5 of these; one for each bedroom, the family room, and an elderly neighbor's bedroom. 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.

Carbon Monoxide MIXES with the air. It does not stay low or high. You can't see it or smell it. That's why it's so deadly.

The piece of mind of having these installed is enormous. More people die of CO poisoning than from fire. If you don't have a CO detector, get one, two, etc. The price is right.
