Alarm Removal; Alarm Replacement - Kidde KN-COSM-BCA User Manual

Operation
Peak Level Memory
If the CO sensor has detected a CO level of 100 PPM
or higher since last reset, it will be recorded by the
Peak Level Memory function. To access the Peak Level
Memory press the test/reset button. If a reading of 100
PPM or higher has been recorded the unit will chirp 8
times. If you've been away from home this feature
allows you to check if there was a CO reading of 100,
or higher, during your absence. Pushing the test/reset
button resets the memory. It's also reset when
batteries are removed.

Alarm Removal

If the tamper resist feature has been activated, refer to
tamper resist feature description on page 6 for removal
instructions. Remove the alarm from the mounting
plate by rotating the alarm in the direction of the
"OFF" arrow on the cover.

Alarm Replacement

Seven years after initial power-up, this unit will "chirp"
twice every 30 seconds to indicate that it is time to
replace the alarm. A label has been provided on the
side of the alarm that has "Replace by" printed on it.
Write the replace by date on the label. The date written
on the label should be after seven (7) years of
cumulative power.
REPLACE IMMEDIATELY! IT WILL NOT DETECT CO IN
THIS CONDITION.
