Within a few minutes, your carbon monoxide alarm will start monitoring for
CO and will continue to do so as long as it receives power.
When the Model KN-COB-DP-LS CO alarm loses power: If you have a good
9V battery installed, the alarm will automatically switch to the battery back-
up mode and the green LED will flash approximately every 10 seconds. The
unit will continue to operate normally and detect CO for at least 20 hours.
If the battery is low or missing, or if the unit malfunctions, it will alarm dif-
ferently to alert you of specific conditions. Please familiarize yourself, and
other family members, of the difference between a CO alarm and an indica-
tion signifying a problem with the unit.
When AC power is restored, the alarm will automatically switch back to nor-
mal operating mode and the green LED will come on continuously. Observe
the CO alarm regularly to make sure the green Operate LED is on, indicating
normal operation. If the green Operate LED is not on, unplug the CO alarm,
then plug it in again. This will clear the alarm for restart. If the green oper-
ate LED does not light, your CO alarm may be malfunctioning.
The following table describes the audible alarm patterns and the recom-
mended actions to take.
