Caution: If the unit detects CO and enters an alarm state
while in battery back-up condition, the CO level will be
displayed and the audible alarm pattern of four quick beeps
will sound once every 60 seconds.
Battery Back-up Operation in Low Battery "Lb" Condition:
When the battery pack is not fully charged, the unit will
begin displaying "Lb" and "chirp" once every 15 seconds.
This will last approximately 7 hours to warn you the
battery is losing capacity. Apply AC power to charge
battery as soon as possible.
NOTE: While in the low battery "Lb" warning mode, the
unit is sensing for and will alarm if CO is detected.
Battery Back-up Operation in Trouble Alarm Condition:
When the battery pack capacity has been discharged to a
state where it can no longer provide enough power to detect
CO and operate the alarm, it will enter a trouble alarm
condition. The display will go blank and the alarm will give
an audible trouble "chirp" once every 60 seconds. This will
continue for approximately 7 hours after which time the alarm
will no longer "chirp" to warn of a trouble condition.
WARNING:The unit will not detect CO while in the trouble
alarm condition, blank display, and one audible trouble
alarm "chirp" every 60 seconds.Apply AC power to charge
the battery as soon as possible.
When AC power is restored, the alarm will automatically
switch back to normal operating mode and begin charging
the battery pack to full capacity. After continued operation
on battery backup, "Lb" may flash while the battery is
recharging and will continue until fully charged.
Constant exposures to high temperatures or high or low
humidity may reduce battery life.
WARNING: Replace the battery pack only with a Kidde
rechargeable battery pack. Replacement battery packs can
be purchased from Kidde customer service. See page 32 for
additional precautions regarding the rechargeable battery
pack.
