GENERAL GUIDELINES FOR INSTALLING
The Model BC-35 battery charger/transfer module complies
with UL Standard 864. The module is designed to monitor
the battery charge status and alert appropriate personnel
when the batteries may not have the standby power
capacity required by NFPA Standard 72 Local, Municipal Tie,
Remote Station, or Proprietary.
The BC-35 charging circuit provides a charging current
only if the voltage of the batteries being used is
between 18.3 VDC and 27.7 VDC. If the battery voltage is
out of this range, the BC-35 will automatically cut off its
CAUTION: Disconnect the system power input before
installing the BC-35 and/or BE-35 cable connections.
The BC-35 module has a trouble signal for both high and
low battery conditions. A trouble condition occurs:
During normal AC operation when the instantaneous
or constant voltage across the battery is more than
30 volts peak or is less than 24 volts.
During the battery backup operation when the
instantaneous or constant voltage across the battery
is more than 30 volts peak or is less than 21 volts.
