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 will 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). Within several seconds the
unit will return to monitor for CO.
Note: You do not need to press the Test button to take a CO
reading.
Battery Replacement
NOTE: This CO alarm is not battery operated.
However, these alarms
are equipped with 8 volt Lithium Ion battery backup – the 8 volt battery
is to supply short term back-up during a power outage.
WARNING: Replace the battery pack only with a Kidde
rechargeable battery pack. Replacement battery packs can be
purchased from Kidde customer service.
Upon initial power up or after the alarm has operated on battery backup
and depending on the charge state of the battery, it could take up to 20
hours to FULLY charge the battery.
During the first 10-hour initial charge period or, until the battery has
charged, “Lb” will be displayed along with the CO level (usually “0”)
and without an audible “beep”. When the initial charge is complete, the
“Lb” will disappear. If however, after 10 hours the battery is not
charging properly, “Lb” may continue to flash AND there will be an
audible “beep” once every 15 seconds indicating the battery is not
charging. If this occurs, make sure the connection between the battery
and the alarm is correctly oriented and fully seated. If not, disconnect
the battery and reconnect insuring the alignment ribs match the slot in
the battery. If it is properly connected and fully seated and “Lb” is still
displayed along with an audible “beep”, contact customer service.
