From The Manufacturer

The First Alert CO615 Plug-In Carbon Monoxide Detector helps protect your family with an electrochemical sensor, an 85-decibel alarm, and an easy-read digital display. It plugs into any standard outlet with no additional mounting necessary. It also includes a battery backup, so CO is monitored even if there’s a power failure. The Peak Level feature displays the highest concentration of carbon monoxide measured since the unit was last reset. One button silences any nuisance alarms, and also tests detector functions. And an end-of-life signal enhances your safety by letting you know when it’s time to replace the unit. Keep your family safer by installing units on multiple levels and in each bedroom. 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. Two AA batteries are included. 7-year limited warranty. UL listed. –Bree Norlander

Expert Reviews

What reviewers liked

May be plugged into a wall socket or operated via battery
The digital display provides more information than most carbon monoxide alarms, not only displaying the levels, but also indicating the CO levels and battery life graphically.
- Tuck
The unit detects and notifies if carbon monoxide is present sounding a loud horn which is at 85 decibels.
The battery backup ensures that the carbon monoxide detector works even if your power isn’t. All it needs is a 9 volt battery.
It comes with Battery back-up which means it doesn't need to be plugged in, and it will also keep working when connected to a power outlet in the event that the electricity fails - which is the most likely time you'll turn to non-electric fossil fuel burning for heating which is also the riskiest time for CO level increases inside the home.
A sensor is included in the device to detect the presence of electrochemical carbon monoxide. It is the most appropriate technology that is available.

What reviewers didn't like

Some questions about accuracy of the manual vs. what is found online
The fact that you can plug it into a power outlet may tempt you to mount in close to the floor, because that's where many of your electricity outlets are.
Bad design on the battery door. It is difficult to read the display.
