How to Know If Your Alarm is Malfunctioning
Your alarm performs an internal self-diagnosis every 15 seconds to
make sure that it is functioning properly. The alarm is designed to
alert you in the unusual event of a malfunction.
If the alarm malfunctions.
In the rare event that your alarm malfunctions, it will alert you with
one of these signal groups (depending upon the type of
malfunction that occurs):
Malfunction Signal Group 1 - Component Failure

– An intermittent “chirping” alarm will sound every 30 secs., and
– An “Err” message will appear on the digital display


Malfunction Signal Group 2 - Microprocessor Failure

– The alarm will sound continuously, and
– The digital display will be blank, and
– The alarm cannot be shut off by pushing “Test/Reset” button

Unplug the alarm immediately and return for warranty exchange
(see “Warranty” on back page).

Low Battery Warning
If the 9V battery is missing, or if the battery’s power is low, an “Lb”
message will display which blink’s alternately with the current CO
reading or “GAS” every second. If this happens, you need to replace
the battery. Refer to page 1-5 for more on low battery warnings.
What to do if you’re not sure...
PLEASE familiarize yourself with the malfunction alert, and do not
confuse these signals with an alarm. After reading the information
above, if you are still unsure whether your alarm is operating prop-
erly, call the KIDDE Safety toll-free consumer hotline at 800-880-

dows for ventilation, extinguish all open flames, do not activate
any electrical switch and evacuate the premises immediately. Then
