DESIGN General
This unit provides one-way all call page to the V-136RTHF. The functions and operation of the intercom unit remain the same as without the all call unit with exception that 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 the factory to insure that the equipment functions properly. To insure proper operation and to prevent equipment damage, please observe the following:
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 double-checked.

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 Valcom Automated Support or visit our website at http://www.valcom.com.
