Part One – Your Kidde CO Alarm

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 per- form as described below, have it replaced immediately. Turn to page 16 “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 and release the Test/Reset button, within 15 seconds if the CO alarm is operating properly, you will hear 4 quick beeps – followed by 5 seconds of silence – followed by 4 quick beeps. 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 front 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 sec- onds 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 30 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 page 34).

What to do if you’re not sure...

PLEASE familiarize yourself with the malfunction alert, and do not con- fuse 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 toll-free consumer hotline at 1 800-581-6742 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 ventila- tion, turn off fuel-burning appliances (like kerosene or oil heaters, fur- naces, 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 ventila- tion. Then call the Kidde toll-free consumer hotline at 1 800-581-6742 for assistance.

Before you call a qualified technician (such as a licensed heating con- tractor, 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 customer service operators are avail- able to answer your questions and assist you in non-emergency situa- tions at no charge.

Never ignore a CO unit’s alarm. A true alarm is an indication of poten- tially 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.
