What To Do If The Alarm Sounds
Because carbon monoxide is a cumulative poison, long-term expo-
sures to low levels may cause symptoms, as well as short-term
exposures to high levels. This Kidde unit has a time-weighted
alarm - the higher the level of carbon monoxide present, the sooner
the alarm will be triggered.
This CO alarm can only warn you of the presence of CO. It does
not prevent CO from occurring, nor can it solve an existing CO
problem. If your unit has alarmed and you've provided ventila-
tion by leaving your windows and doors open, the CO buildup
may have dissipated by the time help responds. Although your
problem may appear to be temporarily solved, it's crucial that the
source of the CO is determined and that the appropriate repairs
are made.
