Normal Operating Characteristics; How To Test Your Co Alarm - Kidde KN-COPP-3 User Manual

Part One – Your Kidde CO Alarm

Normal Operating Characteristics

When you first power up the unit, the alarm will sound briefly
to let you know the unit is receiving power and that the alarm circuit is
functioning.
You should see three eights
the alarm is in the start-up mode. The three eights will remain for approx-
imately 20 seconds. You should see a blinking red
dot to the lower right of the digital display. The
blinking dot shows that the alarm is operating.
Within 20 seconds, your CO alarm will start mon-
itoring for CO. The number indicates a measure-
ment of carbon monoxide in parts per million (ppm). Note: The number
will probably be zero (0). This is a normal condition for most households
and shows that no measurable amount of CO has been detected.
The alarm has begun monitoring the air for carbon monoxide and will
continue to do so as long as it receives power.
When the alarm is unplugged or loses power and you
have a good 9V battery installed, the alarm will automatically
switch to its battery backup mode and you will notice the following:
• The digital display will show a blinking dot only – this helps
conserve the battery's power.
• The digital display will show a number only if it senses
carbon monoxide while in backup mode.
• If CO is detected while on battery backup, alarm pattern
is 4 quick beeps – followed by 5 seconds of silence –
followed by 4 quick beeps. After 4 minutes, alarm pattern
is 4 quick beeps every 60 seconds.
Note: The alarm will operate on battery backup for at least 20 hours.
When AC power is restored, the alarm will automatically switch back to
normal operating mode.
When the alarm is unplugged or loses power and you
have a low battery installed, you will notice the following:
• A fading alarm will sound alerting you the unit has
switched to its backup mode, but the 9V battery is low.
• A blinking dot will be displayed and the sounder will chirp
every 15 seconds.
• When peak level is pushed, the display will alternate
between "Lb." and CO reading.
When battery is depleted:
• A blinking dot will be displayed and the sounder will chirp
approximately every 30 seconds.
• Pressing the test button will result in a chirp approximately
every one second. The alarm will not detect CO if battery
is depleted. Replace battery.

Constant exposures to high or low humidity
may reduce battery life.
We recommend you replace your 9V battery
at least every six months.
How to Test Your Alarm
There are two aspects of the alarm's operation that can be tested: the
electronics and the sensor response. Instructions on testing each are out-
lined below and on the next page.
Testing the Electronics
You should test the alarm once a month, following the directions list-
ed below. If at any time you test the alarm and it does not perform as
described below, have it replaced immediately. Turn to page 1-6 "How to
know if your alarm is malfunctioning" for a description of the charac-
teristics of a malfunctioning alarm and what you should do if a mal-
function occurs.
Observe the alarm weekly to make sure the red dot is
blinking, indicating normal operation.
If the dot is not blinking, unplug the alarm for
three minutes, then plug in again. This will clear
the alarm for restart. If the dot does not resume
blinking, your alarm may be malfunctioning.
To test the alarm, press the Test/Reset button. If the unit is oper-
ating properly, you should notice the following:
• The display shows three eights
a number (usually around 200). You should then hear
4 quick beeps – followed by 5 seconds of silence –
followed by 4 quick beeps. The unit will then show the
three eights for several seconds. It will then return to
monitoring for carbon monoxide.
Familiarize yourself and household members with the alarm pattern
described above. In the event of a CO incident, this pattern will contin-
ue to repeat as long as CO is present.
