DESIGN

General

This unit provides one-way all call page to the
V-136RTHF. The function s an d operat ion of the
intercom unit remain the sam e as without the all call
unit with exception th at dialing "0" energizes the all
call unit and permits a one-way page to all stations of
the intercom.

INSTALLATION

Precautions

All precautions have been taken at th e f actory to insure
that the equipment functions properly. To insure
proper operation and to prevent equi pment damage,
please observe the followin g :
a) Unplug the power supply before connecting any

wires or cables to the control unit connecting
block.

b) Do not locate the control unit more than 5 feet

from the power supply or closer than 18 inches.

c) Do not use a lamp tester to check signals, use a

voltmeter. A lamp tester when first applied is a
short circuit to electronic circuits.

d) Do not apply power to the control unit until all

connections have been dou ble- ch eck ed.

Mounting

Mount the V-1134 clos e to t h e V-136RTHF control
unit allowing enough room for the amphenol
connectors. NOTE: The cable supplied with the unit is
30" long. If units are s eparat ed 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 amph en ol on th e 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 t h e 30" cable su ppl ie d with
the V-1134 should be plugged into the amphenol
marked "to intercom." The other end should plug
into the V-136RTHF in tercom unit.
d) If some stations are to be ex clu ded from the all
call, refer to Figure 2. Punch down two 25
pair female am ph en ol en ded cabl es on a 66 type
solid block. Plug on e cable t o the V-1134 "to
intercom" amphenol and plu g th e s econ d cable to
the V-136RTHF. Connect exclu ded s peakers t o
the appropriate ICM number on the solid block
and to the common s peaker retu rn on th e s plit
block. Connect non-exclu ded speak ers as s h own
in the V-136RTHF ins tal lat ion i n s tru ct ion .

NOTE: Do not connect speakers to stations 0
or 39.

Cross Connections

a) If using th e V-1134 with the V-136RTHF,
perform the follow i n g :

Strap the Y/BN to the G/V on t h e "to 66 block "

•

25 pair cable.

Power Connections

The V-1134 requires no external power connections as
its power is derived from the power su ppl ied t o

the V-136RTHF. Care shou l d be tak e n to make sure
that the power supply is capable of supplying the
increased current requirements when the V-1134 i s i n
use.

OPERATION

When the calling party goes off hook on the in tercom
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 th e O /V l ead of t h e
V-1134 (ICM connector). The V-1134 operat es a
series of relays w ith tran sfer contacts and all stations
are transferred to the outputs of audio amplifiers. After
approximately 1 second th e amplifiers are energized
and the calling party can make a one-way page to all
stations. If station "0" is not di aled, t h e V-136RTHF
units perform in the manner described in their Valcom
System Instru ction s with the speaker leads from the
control units going straight through normally closed
contacts in the V- 1134.

TECHNICAL ASSISTANCE

When trouble is reported, v eri f y that power is being
supplied to the unit and there are no brok en
connections. Check voltages for proper polarity on the
crossconnect block. The table on t h e n ex t pag e
identifies symptoms of some possible problems with
solutions.

If a spare unit is available, continu e to trou blesh oot by
substituting the spare unit for the suspected unit.
