Editorial Product Review:Amazon.com Item 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 CO615 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. Installation is as simple as plugging it in to any wall outlet. Its easy-to-read backlit digital LED display gives you a clear read-out of current CO concentrations in parts per million. The alarm includes a battery back-up giving you peace of mind in a power outage. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. An audible and visual low battery signal alerts you to replace the battery and an indicator alerts you when a battery has been removed. An end-of-life alarm of three chirps alerts you to replace the unit. One 9-volt battery is included. 5-year limited warranty. UL listed.

Simple to Use, Simple to Test, Great Value!
My old carbon monoxide detectors were a different brand, and they were due for replacement. I trusted the First Alert brand and gave these a try. I bought three of them (one for each level of the house). They work great, they are simple to test periodically, and I was very satisfied with the value for the money. I would recommend these detectors to anybody.

It's a CO Alarm
The product appears to work fine. However, I purchased a Kiddy Nite Hawk CO Detector with Digital readout and for some reason, the peak memory level for this product shows about 16PPM while the First Alert Alarm always shows zero.
At this point neither one of the alarms have gone off so I'm hoping that my family is safe.

Hopefully we never have to hear it's alarm
This unit was very easy to install. All we did was plug it in. There is no way for me to give this a full 5 star rating since the alarm has not been needed yet. Hopefully it stay that way.

Plug and play.
No problems. Appears to be working fine. Great piece of mind having it in the house.
