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 20 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 the “Test/Reset” button
Unplug the alarm immediately and return for warranty exchange (see
“Warranty” on back page).
What to do if you’re not sure...
PLEASE familiarize yourself with the malfunction alert, and do not confuse these sig-
nals 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 to do a quick diagnostic check of the alarm over the phone. The customer serv-
ice representative will be able to assist you and answer your questions.
Never ignore a CO alarm. Atrue alarm is an indication of potentially dangerous lev-
els 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, allowing time to resolve the problem
calmly.
