What Carbon Monoxide is and Why You Need a Detector?

Carbon Monoxide (CO) is a colorless, odorless, tasteless and toxic gas produced as a by-product of combustion. Any fuel burning appliance, vehicle, tool or other device has the potential to produce dangerous levels of CO gas.

According to experts, every home with at least one fuel-burning appliance or heater, attached garage, or fireplace should have a carbon monoxide alarm. An alarm should be installed on every level of the home and in sleeping areas.

The Kidde KN-COPP-3 AC powered, plug-in carbon monoxide alarm utilizes sophisticated electronic components and unmatched sensor technology to protect you and your family from the dangers of CO. The KN-COPP-3 includes a 9V battery backup that provides continuous monitoring of CO levels, even during power outages, when AC-only units are not providing protection. The KN-COPP-3 will detect and store measured data of concentrated CO levels as low as 11 and up to 999 PPM with its peak level memory display. This alarm gives you several mounting options, including: direct-plug, a 6’ power cord or table top.
