How the CO alarm determines when to alarm

Your Kidde CO alarm uses advanced technology to monitor the environment in your home and warn you of unacceptable lev- els of carbon monoxide. An internal microcomputer works together with the carbon monoxide sensor inside the alarm to determine the levels of carbon monoxide in the air and to cal- culate the rate that CO would be absorbed into the human body.

The microcomputer is calibrated to trigger the alarm before most people would experience any symptoms of carbon monoxide poisoning. Because carbon monoxide is a cumula- tive poison, long-term exposures to low levels can cause symp- toms, as well as short-term exposures to high levels. Your Kidde CO alarm has a time weighted alarm, so the higher the level of carbon monoxide present, the sooner the alarm will be trig- gered.
