The Kidde KN-COB-DP2 AC/DC carbon monoxide alarm plugs directly into your home's standard wall outlet making installation quick and easy. The 2-AA battery backup provides protection even during power outages when many CO incidences occur. The tamper resist feature can be activated to deter tampering or theft of the unit by sounding a loud alarm if the unit has been unplugged or come loose from the outlet. It is a great option for property owners that are concerned with theft or interference with the CO alarm. The KN-COB-DP2 alarm uses advanced electrochemical sensing technology to monitor for carbon monoxide levels in your home. This alarm has a compact design that does not conceal secondary receptacle space in a standard outlet.

The Kidde KN-COB-DP2 plug-in carbon monoxide alarm with battery backup provides you and your family with a warning signal to protect against dangerous levels of carbon monoxide in your home. The rotating AC blades allow for use in vertically or horizontally oriented outlets and the preinstalled backup batteries with pull tab make setup fast and easy. The green LED shows that AC power is present and the alarm is working properly. The red LED will illuminate when the alarm detects carbon monoxide and indicates that you and your family should move to fresh air. The Low Battery Hush feature temporarily silences the low battery chirp in order to maintain protection without having to replace the batteries at an inconvenient time. With the Event Memory feature, if the unit has detected a CO concentration of 100ppm or greater the green LED will flash every 10 seconds, which can be helpful in recognizing a CO event after being away from home. This carbon monoxide alarm is UL Listed and offers a 10 year limited warranty.
