TROUBLESHOOTING GUIDE
ENTRY # PROBLEM POSSIBLE CAUSE SOLUTION
Door station does not call
in (no call tone or LED
light).
Missing jumpers Are there 2 or 3 conductors run to the door station? If 2 wires, jumper must
remain attached between
E
and
—
at both the door station and the master
station. Replace jumper. In a multi-master system, the
E
/
—
jumper
should be removed and 3 wires should be connected.
Door station does not call
in (no call tone or LED
light) -- 3-wire connection.
Missing connection of
—
terminal.
If communication works, check connection between
—
terminal of door
station and master. Test call-in at master station by touching a jumper wire
between # and
—
terminal of master. If this rings the tone and lights the
light, the
—
wire from the door station is not connected properly.
Door station does not call
in (no call tone or LED
light) -- 3-wire connection.
Mis-wiring of
1
and
E
terminals.
Check that the
1
and
E
wire are not reversed. If they are, communication
will work but call-in will not.
No communication to
door station.
Mis-wiring of
E
terminal.
Communication is between the
1
and
E
terminal of the door station to a #
and
E
terminal of the master station. If call-in works, check the
E
wire for
continuity. Check the
1
and
E
wires at the sub to ensure that they are not
reversed.
