Use and Care Manual

7. Maintenance
NOTE: This unit is sealed. The cover is not removable.
Due to the loudness of the alarm, we suggest that you place your
fingers over the sounder opening while testing your alarm.
CAUTION: Continuous exposure to the high sound level of this
alarm over an extended period of time may cause hearing loss.
Testing
To test the alarm, press the Test/Reset button. If the unit is operating
properly, you should hear 4 quick beeps – followed by 5 seconds of
silence – followed by 4 quick beeps. The display will show three “eights”
and then show a number – usually around 200). The red LED will flash
along with the beeps and the amber LED will illuminate. Within several
seconds the unit will return to monitor for CO.
If interconnected to Kidde smoke alarms, pressing the Test/Reset button
on the CO alarm will have no effect on the smoke alarms. The smoke
alarms will not be tested and will not alarm. However, when pressing
the Test button on an interconnected smoke alarm, the CO alarm will
emit a Smoke/Fire audible and visual alarm pattern of 3 long beeps, 1
second of silence, repeated. NOTE: You do not need to press the Test
button to take a CO reading.
Battery Backup
This CO alarm is not battery operated. However, the alarm is equipped
with a rechargeable battery to supply short term back-up during a
power outage.
IMPORTANT: Constant exposures to high or low humidity may
reduce the life of your battery and alarm.
End of Life Notification
Seven (7) years after unit is first powered, this alarm will “beep” every
30 seconds and display "End" to indicate that it is time to replace the
alarm (see Alarm Removal section for instructions). By pressing the
Test/Reset button the audible notification will be silenced for up to two
days giving you time to replace the unit at a more convenient time. The
display will alternate between the the CO ppm reading and "End" to
remind you to replace the unit right away. This silence feature can only
be used for a few days before it will no longer function and the beep
cannot be silenced. The alarm will still monitor and alarm for CO during
this period but all other functionality will be lost.
Once AC power has been removed from unit after reaching its end of
service life, the battery will discharge itself to render the unit safe for
disposal.
