Problem Possible Cause & Solutions
Can’t clear fault
notication:
• Refer to the explanation of system faults list on page 19 to verify the
fault type.
• If the fault is for the external line, verify the line has active dial tone,
voltage, and can place a call in and out.
• If the fault is for a loop break, verify the wiring and pin out between the
locations listed in the fault code on the BOSS display.
• If fault is for over-current or under-voltage, verify the pin-out of the
wiring between call boxes. Wiring should be connected in a daisy-
chained scheme only. Wires cannot be spliced in to a loop.
• Conguration faults will be due to a mismatch of the information
entered into the conguration software and what is connected to the
BOSS controller.
• Verify no more than 24 call boxes are connected to a single loop.
• See additional help with fault codes within this troubleshooting section.
Call Box has no power
LED:
• Verify the call boxes are only connected to L2A or L2B. See page 7 for
a detailed connection diagram.
• Verify the pin-out of the 4-pin terminal connector. See page 7 for full
pin-out details.
• Verify the wires are seated into the terminal connector properly and
secured rmly within the screw terminals.
• Verify the wire in the terminal connectors is stripped back with minimal
amounts of the raw wire conductor visible after securing.
• Verify maximum loop length isn’t being exceeded. A single loop cannot
be more than 1200 ft.
• Verify the rst call box is within 200 ft. of the BOSS controller.
• Verify the call boxes have 44-48vdc on pins 1 and 4 of the terminal
connector.
System has a Ground
Fault Error Code:
• Verify no more than 24 call boxes are connected to a single loop.
• Identify which call box is causing fault by looking for the rst call box in
the loop without it’s power LED illuminated. Try swapping that call box
with a known, good unit to see if issue follows call box.
• Verify the wires in the terminal connector are not touching or broken
o inside of connector.
• Verify the wires going from call box to call box are truly daisy-chained
with no wires spliced in that could break the loop.
