to terminal E3. Connect the return lead from the external
discharge return bus located on the cable rack to solder terminal

lost to fuse panel number 1, the frame alarm will not light.
Alarm
Verification
Perform the following verification procedures with the load
buses powered from the battery plant, but with no load
equipment in service.
Simulate a fuse failure alarm on each panel using a blown GMT
fuse. Insert the GMT fuse in one of the GMT indicating fuse
positions on each fuse panel. Verify that the red LED on the
associated BEP1 circuit pack lights as well as the frame alarm
lamp at the top of the cabinet. If remote alarms are connected,
verify that office alarms are generated as specified by the job
records.
Simulate a panel power loss alarm on each fuse panel by turning
off or disconnecting the circuit breaker or fuse feeding each load
bus. Verify that the green LED on the associated BEP1 circuit
pack is extinguished and that the frame alarm lamp at the top of
the cabinet lights. If remote alarms are connected, verify that
office alarms are generated as specified by the job records.
If alarms are not indicated as described, re-check alarm wiring
on T-83150-30, Figures 6 and H2. If alarms still do not function,
it may be necessary to replace the BEP1 circuit module,
comcode 106849506.
