2.3 WHAT HAPPENS WHEN YOUR CO ALARM DETECTS CARBON MONOXIDE ?
When the Ei262 CO Alarm detects potentally dangerous levels of CO, it flashes the red alarm light and
then sounds a loud alarm if the CO persists and transmits a RadioLINK alarm signal.
Table B below shows how the CO Alarm reacts to different levels of CO gas and exposure time. At higher
levels of CO the alarm turns on sooner. The rate of flashing of the red light indicates the level of CO.

If your CO Alarm sounds follow the instructions on page 4.
When ventilation is provided by leaving windows and doors open, the CO build up may have
dissipated by the time help arrives and the alarm may have stopped sounding. Although your problem
may appear temporarily solved, it is crucial that the source of the CO is determined and appropriate
repairs made.
