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:
To test, press the test/reset button.
Test the unit weekly!
The unit will perform a self diagnostic test by cycling through the
alarm pattern.
Familiarize yourself and family members with the alarm pattern.
A CO alarm is 4 short beeps – followed by 5 seconds of silence –
followed by 4 short beeps. This cycle will repeat in the event of a
CO alarm. This cycle will continue for the first 4 minutes of a CO
alarm and then change to one cycle every one minute until the
device is reset or the CO is eliminated.
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. If the CO alarm sounds
again within six minutes, it is sensing high levels of CO which
can quickly become a dangerous situation.
If this happens follow What To Do If The Alarm Sounds on pages
18-20. 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.
