Part One – Your Kidde CO Alarm

When the Model KN-COB-DP-H CO alarm is unplugged or loses power, a fading alarm will sound briefly to alert you that it has been disconnected from its power source. For example, this fading alarm will sound in the event of a power outage. A brief alarm will also sound to alert you when the power is restored.

THIS CO ALARM WILL NOT OPERATE WITHOUT 120V AC POWER. When the Model KN-COB-LCB-A CO alarm loses power: If you

have a good 9V battery installed, the alarm will automatically switch to its battery backup mode and you will notice the green LED flashing approximately every 10 seconds. The unit will con- tinue to operate normally and detect CO for at least 20 hours.

When AC power is restored, the alarm will automatically switch back to normal operating mode and the green LED will come on continuously.

When the Model KN-COB-LCB-A CO alarm is unplugged: If the

unit is unplugged it will produce a constant tone until the bat- tery is removed or the unit is plugged back into the wall unless the Tamper-Resist feature has been deactivated or disabled as described in the feature section.

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. See the following section for a description of the characteristics of a mal- functioning 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, then plug it in again. This will clear the alarm for restart. If the green operate light does not come back on, your CO alarm may be mal- functioning.

To test the CO alarm, press and release the Test/Reset button, 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. 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.

Caution: Continuous exposure to the loud 85 decibel alarm at close range over an extended period of time may cause hearing loss.
