7.22.5 Bell Circuits Status Holding Registers
NFS2-640 and NFS-320 Only

Each of the bell circuits status holding registers are divided into an upper and lower byte
as described below and in
• Upper Byte: The upper byte contains general status information about the bell circuit.
• Lower Byte: The lower byte is primarily used when bit 11 in the upper byte is a '1' (or
active). When bit 11 is a '1',
information about the active bell circuit. The lower byte will be all 0's if the bell circuit is
not in an active state.
Specifically, the lower byte contains the actual active event for this bell circuit. An active
state is defined in this gateway as any Fire, Security, Critical Process, Medical, Mass
Notification, or Supervisory alarm state.
If the bell circuit is not present in the panel programming, all bits in the lower byte will
contain a '1' or the value 'FFH', but the upper byte will contain a '0'.
