dangerous levels of carbon monoxide, it ashes the red
light immediately and then sounds a loud alarm if the
carbon monoxide persists.

The below table shows how the alarm reacts to
different levels of carbon monoxide gas and exposure
time. At higher levels of carbon monoxide, the alarm
turns on sooner.
The rate of ashing of the red light indicates the level
of carbon monoxide. If your alarm sounds, follow the
instructions in the “What To Do” column.
Caution: The alarm only indicates the presence of carbon
monoxide gas in the area where the ADT Carbon Monoxide
Alarm is located. Carbon monoxide gas may be present in
other areas.
