Mounting
Mount the V-1134 close to the V-136RTHF control
unit allowing enough room for the amphenol
connectors. NOTE: The cable supplied with the unit is
30" long. If units are separated by more than 30",
additional cable may be required.
Cabling
NOTE: In a mixed system of Bell/Buzzer and
voice signaling, stations 30-29, 0, and 5-9
must be voice signaling. Bells or buzzers
must be connected as excluded speakers
(See Figure 2).
a) In a new installation, complete all steps of the
installation procedure as shown in the instruct-
ions for the V-136RTHF, combination.
Connect the 25 pair intercom cable from the 66
type split block to the amphenol on the V-1134
marked "to 66 block."
b) In an existing system without all call, remove the
intercom cable from the V-136RTHF and plug it
into the amphenol on the V-1134 marked "to 66
block."
c) If all speakers are to receive all call, refer to
Figure 1. One end of the 30" cable supplied with
the V-1134 should be plugged into the amphenol
marked "to intercom." The other end should plug
into the V-136RTHF intercom unit.
d) If some stations are to be excluded from the all
call, refer to Figure 2. Punch down two 25
pair female amphenol ended cables on a 66 type
solid block. Plug one cable to the V-1134 "to
intercom" amphenol and plug the second cable to
the V-136RTHF. Connect excluded speakers to
the appropriate ICM number on the solid block
and to the common speaker return on the split
block. Connect non-excluded speakers as shown
in the V-136RTHF installation instruction.
NOTE: Do not connect speakers to stations 0
or 39.
Cross Connections
a) If using the V-1134 with the V-136RTHF,
perform the following:
•
Strap the Y/BN to the G/V on the "to 66 block"
25 pair cable.
Power Connections
The V-1134 requires no external power connections as
its power is derived from the power supplied to
the V-136RTHF. Care should be taken to make sure
that the power supply is capable of supplying the
increased current requirements when the V-1134 is in
use.
OPERATION
When the calling party goes off hook on the intercom
and dials "0", the intercom switching network closes a
contact for station "0". This contact connects a
resistive ground supplied by the Y/BN lead of the
V-1134 (ICM connector) back to the O/V lead of the
V-1134 (ICM connector). The V-1134 operates a
series of relays with transfer contacts and all stations
are transferred to the outputs of audio amplifiers. After
approximately 1 second the amplifiers are energized
and the calling party can make a one-way page to all
stations. If station "0" is not dialed, the V-136RTHF
units perform in the manner described in their Valcom
System Instructions with the speaker leads from the
control units going straight through normally closed
contacts in the V-1134.
TECHNICAL ASSISTANCE
When trouble is reported, verify that power is being
supplied to the unit and there are no broken
connections. Check voltages for proper polarity on the
crossconnect block. The table on the next page
identifies symptoms of some possible problems with
solutions.
If a spare unit is available, continue to troubleshoot by
substituting the spare unit for the suspected unit.
Assistance in troubleshooting is available from the
factory. When calling, you should have a VOM, a
telephone test set, several clip leads available and be
calling from the job site. Call (540) 427-3900 and ask
for Technical Support, or call (540) 427-6000 for
