3.1 How does your CO Alarm work?
When the CO Alarm detects levels of CO (above 43ppm), it flashes the red LED. If the CO
level persists, then the CO Alarm will sound a loud alarm to warn the occupants. Table B
shows how the CO Alarm reacts to different levels of CO gas and exposure time. At higher
levels of CO the CO Alarm will sound quicker. The rate of flashing of the red light indicates
the level of CO.
