Features and Operation of Digital Display and
Non-digital Display Models
Test/Reset Button
The test/reset button is used to test the unit’s electronics and to
reset the unit during alarm.
Test the unit:
• Test the unit - To test, press and release the test/reset but-
ton, you should hear one short beep - followed by 5 seconds of
silence – followed by a continuous alarm with a corresponding
red LED flash.
Familiarise yourself and family members with the alarm pattern.
Test the unit weekly! If at any time your unit does not perform as
described replace it immediately.
Note: For Digital Display Models
After the test/reset button is pressed, numbers appear on the
display. These are not CO readings and are part of the internal
testing process. Ignore these numbers !
Due to the loudness of the alarm we suggest you place your fingers
over the sounder opening when testing your Kidde CO Alarm.
Reset
If the alarm is sounding, pressing the test/reset button will terminate
the alarm. If the CO condition that caused the alert in the first
place continues, the alarm will reactivate. Reactivation times
depend on the amount of CO that caused the CO alarm to initially
alarm and the amount of CO present after resetting the alarm .
If this happens follow What To Do If The Alarm Sounds on pages
17-19
WARNING: Tampering with your alarm may cause a malfunction.
Please follow manufacturer’s instructions at all times.
