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
seconds, and an “Err” message will appear on the digital
display
OR,
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 it for warranty
exchange.
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 properly, call the Kidde toll-free
consumer hotline at 1-800-880-6788.
Never ignore an alarm. A true alarm is an indication of
potentially dangerous levels of carbon monoxide. CO
alarms are designed to alert you to the presence of carbon
monoxide before an emergency, before most people would
experience symptoms of carbon monoxide poisoning,
giving you time to resolve the problem calmly.
