Testing the Electronics

You should test the alarm once a week, following the directions
listed below. If at any time you test the alarm and it does not perform
as described below, have it replaced immediately. Turn to page 1-10
"How to know if your alarm is malfunctioning" for a description of the
characteristics of a malfunctioning alarm and what you should do if a
malfunction occurs.
Observe the CO alarm regularly to make sure the green operate light
is on, indicating normal operation.
If the green operate light is not on, unplug the CO alarm for three
minutes, then plug in again. This will clear the alarm for restart.
If the green operate light does not come back on, your CO alarm may
be malfunctioning.
To test the CO alarm, press the Test/Reset button. If the CO alarm
is operating properly, within seconds you will hear the pulsing alarm.
This will continue for approximately seconds. Notice the Red Alarm
Light flashes when the unit alarms.
When you test the CO alarm, we advise you to place your finger over
the sounder opening in the upper centre of the CO alarm.
Within a minute, the alarm will then return to monitoring for carbon
monoxide.
NOTE: Pressing the Test/Reset button tests the functions of the
CO alarm's internal components, circuitry and micro-computer.
YOU DO NOT NEED TO PRESS THE TEST BUTTON TO TAKE
A CO READING.

How to Know If Your Alarm is Malfunctioning

Your CO alarm performs an internal self-diagnosis every fifteen seconds
to make sure that it is functioning properly. The CO 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 60 seconds.
OR
Malfunction Signal Group 2 - Microprocessor Failure
– The alarm will sound continuously, and
– The alarm cannot be shut off by pushing the "Test/Reset" button
Unplug the CO alarm immediately and return for warranty exchange (see
"Warranty" on back page).
What to do if you're not sure...
PLEASE familiarise 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 CO alarm is operating properly, call the KIDDE
Safety Europe Ltd consumer hotline on 01753 685148 to do a quick
diagnostic check of the alarm over the phone. The customer service
representative will be able to assist you and answer your questions.
If your CO alarm sounder is beeping, and you are not sure if it is a CO
alarm or a malfunction alert, reset the alarm, open windows for ventilation,
turn off fuel-burning appliances (like kerosene or oil heaters, furnaces, gas
ranges, wood-burning stoves, water heaters, or other fossil-fuel burning
appliances). For furnaces, you can simply turn down the thermostat to its
lowest setting. Open windows and doors for ventilation. Then call the
KIDDE Safety consumer hotline on 01753 685148 for assistance.
Before you call a qualified technician (such as a licensed heating
contractor, utility service technician, chimney sweep or fuel provider) to
check your residence for CO, remember that you will probably be charged
for a service call. KIDDE Safety customer service operators are available to
answer your questions and assist you in non-emergency situations at no
charge.
Never ignore a CO unit's 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.
