V-136RT
36 STATION ROTARY-TONE INTERCOM
GENERAL
The V-136RT is a single-path dial select
microprocessor controlled intercom and page control
unit used with a 1A2 key system to provide 36 zones
of bell or buzzer signalling.
The V-136RT control unit has received an FCC type
KX registration; designed to be used with FCC
registered key telephone systems. In accordance with
FCC rules with applicable tariffs, this paging unit
may only be installed with the authorization of the
host system. Installations may be made by Valcom,
Inc., an authorized agent of the same, equipment
manufacturers, telephone companies, registered
telephone refurbishers, and those qualified for
installation of FCC registered systems under FCC
Rules Section 68.215. The FCC Registration
Number, BAF9I7-69366-KX-N, will be listed in the
affidavits filed with the telephone company; it will be
also be recorded in the system log kept by installation
and maintenance personnel. The local telephone
company is to be notified when this intercom unit is
installed.

INSTALLATION
Precautions
All precautions have been taken at the factory to
insure that the equipment functions properly when
installed correctly. Please observe the following
precautions before applying power to the equipment
or the equipment may be damaged and the warranty
voided.
•Unplug the power supply before making any
connections to the control unit.
•Do not locate the control unit closer than 18
inches or further than 5 feet from the power
supply.
•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.
•Do not apply power to the control unit until all
connections have been double-checked.
Mounting
Mount the V-136RT on a 7" KTU mounting, relay
rack or on the wall.
Connections
•Fasten a 25 pair cable to the unit and terminate
all leads on a 66 type block per Figure 1, 2 or 3.
•Strap 1 ground, B ground, lamp ground, 18 Vac
and 105 Vac signal grounds common at power
supply.
•Refer to Figure 1 for connections; use the chart
in Figure 1 to set the option programming.
NOTE: Option switches 3 and 4 must be in the off
position for proper operation with bells or
buzzers.
•Refer to Figure 2 for connections for 36 stations
of buzzer signalling. This figure may also be
used for 36 stations of bell signalling by
replacing the 18 Vac buzz voltage with 105
Vac ring voltage.
•Refer to Figure 3 for connections for mixed
signalling with 20 stations of bells and 16
stations of buzzers.
OPERATION
To make an intercom call, go off-hook and dial the
number of the desired station. Dial tone will be
broken after the first number is dialed. A one second
ringback tone will indicate that the called station is
being signalled.
To rering the same station, press the "*" button. The
station will be signalled as long as the * button is
held. To rering rotary, dial "1". The station will be
signalled for one second each time a "1" is dialed.
For conference calling (tone only), dial the first
station number, press the "#" button to receive dial
tone, then dial the next station number.
General Method of Operation
When the calling party goes off-hook, the switch
hook contacts in the telephone set close the tip and
ring to form a loop. Loop closure detection logic
then operates the lamps at all stations and returns dial
tone to the telephone set. Dial detection circuitry will
then receive dialing information and operate relays
and/or circuitry to supply signalling voltage to the
desired station.
TECHNICAL ASSISTANCE
When trouble is reported, verify that:
•All telephone sets are in proper working order
•Power is being supplied to the unit
•There are no broken connections at the
connecting block
•The conductors of color coded cables are
terminated in the proper order
If trouble still exists, additional checks should be
made using the following equipment:
•Voltmeter
•Tone-dial single-line instrument (for tone-dial
systems)
•Telephone Test Set
•Clip leads
Before proceeding further, check the voltages at the
connecting block. An undetected blown fuse or low
voltage will cause improper control operation. DC
voltage measurements are made with respect to (+)
ground.
If a spare unit is available, continue to troubleshoot
by substituting the spare unit for the suspected unit.
If the trouble has not been located, refer to the
Troubleshooting Chart. Identify the symptoms and
perform the corrective actions indicated. After all the
suggested tests have been performed, the trouble still
exists, call Valcom at [phone] and ask for
