The First Alert CO615 Dual-Power Carbon Monoxide Plug-In Alarm alerts you to dangerous carbon monoxide. This carbon monoxide detector operates on a dual-power system with battery backup for continuous monitoring, even in the event of a power outage. The backlit digital screen tells you at a glance what the carbon monoxide and power levels are. The CO monitor also features a convenient test and silence button and an end-of-life timer that lets you know when it is time to replace the unit.
Dual-Power Design for Continuous Monitoring
The carbon monoxide detector is designed to work with any standard outlet, and it features battery backup to allow continuous monitoring of carbon monoxide levels in the event of a power outage. Simply place two AA batteries in the battery compartment, and if the power goes out, the backup will activate, monitoring carbon monoxide levels even during storms. A low-battery indicator light and alarm will sound when the batteries need to be replaced or are removed.
Advanced Electrochemical Sensor
The First Alert Dual-Power Carbon Monoxide Plug-In Alarm uses an advanced electrochemical sensor to detect elevated CO levels. This sensor offers increased sensitivity to carbon monoxide even at low levels. In the event of a false alarm, the silence/test button can be used to turn off the CO detector.
Backlit Digital Display is Easy to Read
The large backlit display on the carbon monoxide detector clearly shows the level of carbon monoxide in the room, as well as the power level of the backup batteries. The display is readable even in the dark and casts a calm blue light, making it ideal for use in a bedroom. The 6-foot power cord makes it easy to mount the CO monitor on a wall or position it on a shelf or nightstand.
Where To Place Carbon Monoxide Alarms:
One on every level of the home and one in each sleeping area.
First Alert Carbon Monoxide Alarm CO615
This Alarm can be plugged directly into a wall outlet located close to the floor.
If you are going to use your Alarm as a direct plug into an outlet that is mounted horizontally (sideways), you may want to rotate the adapter 90 Degrees, as follows:
Installation tips for power cord models: The power cord option provides more flexibility in mounting locations and allows the Alarm to be easily installed at or above eye level. NOTE: If you mount the Alarm high on a wall, make sure it is at least 4 inches (102 mm) down from the ceiling. Any higher than this, it will be in "dead air" space and carbon monoxide may not reach the sensor. NOTE: Do not cover the Alarm with a curtain. To install for a wall-mount, you will need to pull out the removable adapter and power cord, as follows:

Very easy to set up and install, fortunately I have not had the opportunity to find out if it works but I trust that it does, and this is the 3rd one I've added to replace ones the previous owner of my house installed and have since expired.

Easy to install
Just plug it in super easy. Hopefully I'll never have the chance to see how it operates.

CO Detector ordered for a friend
I ordered this detector for a friend who is technically challenged because this device is very easy to install, has a very loud alarm, simple to test, and most importantly a visual display showing the CO level when it does alarm. The price is reasonable given there is a 7 year warranty. I wouldn't hesitate to buy one again.

CO Detector Easy to Install & Read
This detector can be installed in a normal A/C plug or mounted near the ceiling using the included extender cord on the plug. I like the visual display and the 7 year warranty. I do recommend this device.

Screen display messages
My 3rd CO2 monitor in as many weeks. Easy to install, in a lower to the ground location. Location and screen make testing and reading test the display easy. Needed more explicit instructions about what a real alarm condition would be like. Had to consult a pro.

CarbonMonoxide Display w/BatteryBackup
I would give it excellent, but on one of them I ordered several the little door in front wont stay closed. Other than that needed to replace it all is good, and when I replaced, I replaced with the same model.
