TROUBLESHOOTING GUIDE (Cont.)
ENTRY # PROBLEM
POSSIBLE CAUSE
SOLUTION
5
No master-to-master
communication.
C terminals mis-wired
between masters.
Communication between masters is carried on the # wire of the calling
master to the C terminal of the receiving master. Verify that the C terminal
of the master that is being called is actually wired to the #terminal that is
being selected on the calling master.
6
LEF master has no
communication or tone, but
LED lights work.
Wrong power supply is
being used.
The LED lights will operate with a power source from 6VDC - 24VDC. The
amplifi er in the LEF unit will only work when the system is supplied 12VDC.
Proper power supply is the PS-1225/UL/S, or PS-1215 DIN.
7
Feedback when the volume
control is turned up over
halfway.
E / — jumpers attached
in a multi-master system.
Remove E / — jumpers on masters and door stations in the system,
provided there are 3 wires to the sub(s). If the sub only has 2 wires in a
multi-master system, the jumper must remain in place for the door call-in to
work. In this case, the side effect is the feedback problem when the audio
volume is turned up. The only alternative is to run the proper wire to the
door station(s) and remove all of the jumpers.
8
New installation has AC
buzz, noise, or hum in
system.
Too close to AC and/or
incorrect wire was used.
If the units are too close to an AC source such as AC wiring or dimmer
switches, move the intercom at least one stud space away from the AC
source. Other precautions include using shielded cable. If shielded wire was
used and there is still AC noise, tie all the shields together and ground to
an earth ground or negative on the power supply. If more than one jacketed
cable was used between masters, make sure the # terminals, C terminal,
and the E terminals are all in the same jacketed cable. If multiple cables
were used, include an E wire in each cable that carries a station number
wire in it.
9
Door release does not work.
Miswire or lack of RY-PA
relays.
Check the WHITE wire coming out of the PC board for voltage. When
depressing the Door release (
) button, 12VDC is present across WHITE
and — , which activates the relay. Ensure that the BLACK wires of the
RY-PA are connected to WHITE and either the BROWN , RED , or
ORANGE wire for selective door release (which provides selective ground
when the corresponding channel is selected).
10
No call tone between
masters.
No Privacy feature on LEF-
3L.
Features not available
The LEF-3L unit does not have the PRIVACY feature or the ability to send
a call tone to another master station (as with the standard LEF-3). This
function is removed to allow the switch to be used for door release instead
of privacy.
11
Can't release the door from
the 2nd (additional masters)
Wiring not connected
properly.
If door release works from the fi rst master but not another(s), verify that
selective door release wires are connected between masters. ( WHITE ,
BROWN , RED , ORANGE ). RY-PA's are only required at one master.
12
External Signaling device
doesn't activate
RY-AC mis-wired
Make sure that the WHITE wire of the RY-AC is connected to the #
terminal that is to be activating the relay, and that RED and BLACK are
connected to
+
and — , respectively.
