Lucent Technologies Lineage 2000® Battery Distribution Fuse Bay (BDFB)
4 - 12 Installation

Power Loss Alarm
Remote monitoring of power loss is furnished for individual fuse
panels. However, power loss alarms will probably not be
remotely monitored in most applications because loss of power
in a BDFB usually results in a number of other simultaneous
alarms from the battery plant and load equipment. If power loss
alarm for the entire cabinet is desired, the installer must connect
the alarm module output pins P101 - 1, 2, 3, 4, 9, 10 as shown in
Figure 3-19. The connections can be made with 26 gauge solid
wire soldered or wire-wrapped to the 405095043 output
connectors furnished with each alarm module.
Monitoring
Multiple Alarm
Modules for
Positive Plants
Opto-isolator U101 is current-direction sensitive. Therefore
remote monitoring of frame alarms for positive plants is wired
differently than for negative plants. For positive plants, fuse
alarms on multiple packs should be daisy-chained together via
P101. This allows the remote fuse alarm signal on any pack to be
monitored from the position 1 alarm module. Three Form C
contacts are provided. They must be connected to alarm module
output pins on connector P101 5, 6, 7, 8, 11, 12, 13, 14 and 15
(see Figure 3-20). The connections can be made with 26-gauge
solid wire and wire-tapped to the 405095043 output connector
provided with each alarm module.
Frame Alarm
Lamp
A frame alarm lamp is located at the top of each cabinet. This
frame alarm lights when power to a fuse panel is lost or there is
a fuse alarm. Power for lighting the frame lamp is from an
auxiliary battery supply (ABS) lead which is a 22-gauge wire
run from the battery plant. Refer to Figure 3-17 for frame alarm
and ABS termination points. The ABS lead is soldered to
terminal E3 and the ABS return lead is soldered to terminal E4
for a negative plant (positive ground). Reverse these leads for a
positive plant (negative ground).
Each cabinet has a 48-volt lamp for use with the ABS lead. If
another voltage is used, change the lamp (24-volt comcode
407226836 or 130-volt comcode 407227164) to agree with the
ABS voltage.
If no ABS lead from the battery plant is available, an installer
may choose an alternative alarming method, substituting power
from a load bus for ABS. For a negative plant (positive ground),
run a 22 gauge wire from the battery bus of fuse panel number 1
