Supplemental
Alarm Input
In addition to the 20 sets of “Form-C” alarm outputs available on the
BJT TB2 and TB3 terminal blocks, the following additional related
alarm wiring may be necessary. Which of these alarms are to be wired
and how or where they terminate outside of the Galaxy is the
responsibility of the party engineering the system.
TB3-5 FAJ: Fuse Alarm Major
A battery potential input is required, using an external 1K ohm, 2W
current limiting resistor at the source. This circuit is usually wired into
the Galaxy plant distribution fuse/circuit breaker alarm circuit.
TB3-6 FAN: Fuse Alarm Minor
A battery potential input is required, using an external 1K ohm, 2W
current limiting resistor at the source. This circuit is usually wired into
the Galaxy plant capacitor charge alarm circuit.
TB3-7 OS: Open String Alarm
A battery potential input is required, using an external 1K ohm, 2W
current limiting resistor at the source. This circuit is used to signal
Galaxy that a battery string protective device or switch is in the open
position.
TB3-21 AMJ: Aux Major
A battery potential input is required, using an external 1K ohm, 2W
current limiting resistor at the source. This circuit is used to allow
Galaxy to monitor another power device and provide alarms for it.
TB3-22 AMN: Aux Minor
A battery potential input is required, using an external 1K ohm, 2W
current limiting resistor at the source. This circuit is used to allow
Galaxy to monitor another power device and provide alarms for it.
TB3-30,46,31,47 ABS1, ABS2, ABS3, ABS4:
Alarm Battery Supply 1 to 4
Plant voltage source for user alarm systems. A 1 1/3 amp ABS fuse
provides power for these points and is located on the BJF card.
TB3-16 LVDF: Low Voltage Disconnect Fail
A battery potential input is required, using an external 1K ohm, 2W
current limiting resistor at the source. This circuit is used to inform
Galaxy that the monitoring circuit for an external Low Voltage
Disconnect device has failed.
TB3-37/38 LDV/LVDR: Low Voltage Disconnect Active
A closure between these points informs Galaxy that an external Low
Voltage Disconnect contactor has opened.
