VSP-V-119RTVA/119RTHF
Issue 7
This paging unit has received an FCC type KX
registration and is designed to be used with FCC
registered key telephone systems. Installations may
be made by Valcom, Inc., telephone equipment
manufacturers, telephone companies, registered
telephone refurbishers, and those qualified for
installation of FCC registered systems under FCC
Rules Section 68.215.
In accordance with FCC rules with applicable tariffs,
this intercom unit may only be installed with the
authorization of the owner of the host system.
The FCC Registration No. BAFUSA-69358-KX-N,
will be listed in the affidavits filed with the telephone
company; it will also be recorded in the system log
kept by installation and maintenance personnel. The
local telephone company is to be notified of the FCC
Registration Number when this intercom unit is
installed.
This equipment ge nerates and uses r adio frequency
energy and if not installed and used properly, that is,
in strict accordance with the manufacturer's
instructions, may cause interference to radio and
television reception. It has been tested and found to
comply with the limits for a Class B computing
device, in accordance with the specifications in
Subpart J of Part 15 of the FCC Rules, which are
designed to provide reasonable protection against
such interference. If this unit does cause interference
to radio and television reception, which can be
determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient the receiving antenna.
• Relocate the equipment with respect to the receiver.
• Plug the equipment into a different branch circuit.
• Move the equipment away from the receiver.
SPECIFICATIONS
Purpose
•To provide 19 stations or zones of handsfree talkback
to 1A2 key systems, electronic key systems, or
PABX trunk positions (V-119RTHF).
•To provi de 19 zones of voice announce signaling to
with one-way amplified speakers (maximum 40 per
zone).
NOTE: One-way amplified speakers may also be
used with the V-119RTHF in areas where talkback is
not required.

INSTALLATION
These instructions cover only the installation
procedures for the Valcom V-119RTVA and
V-119RTHF. Consult the installation instructions for
other equipment that may be used. Installation
procedures are the same for the V-119RTVA and
V-119RTHF.
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:
•Unplug the power supply before making any
connections to the control unit.
•Do not locate the control unit closer than 18
inches or farther 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.

__ 3.Refer to Figure 1 for connecting block
layout and connections.
Limit cable runs to talkback speakers to not more
than 800 feet. Do not split pairs.
Limit audio runs to one-way amplified speakers to
not more than 5000 feet. Limit power runs to
one-way speakers to maximum recommended for
the particular speaker type (see applicable
instruction).

Key Systems.
__ 5.Refer to Figure 3 for connections to

positions.
Settings
Wire Jumper JP1 controls the 15 second Repeat Alert
Tone. The Repeat Alert Tone is disabled with the
jumper in place and is enabled by cutting or removing
the jumper.
For off-hook speaker cancel circuit, each ICM "A"
lead must be connected through a 10K 1/4 W 5%
resistor to the inhibit input (GN/V) (refer to Figure
2). When "called" station or any other party goes
off-hook, the presence of two resist ance grounds
cancels or turns off speaker. "Handsfree" mode can
only be restored by terminating call and redialing
station.
Volume Controls
The phone to speaker level should be at a normal
listening level.
Speaker to phone level: this is the most critical level;
set the volume at the lowest practical level. (It is
better to set it too low than too high).
OPERATION
To make a voice page, go o ff-hook and dial the
number of the desired zone or station. Dial tone will
be broken after the first number is dialed. A one-half
second ringback tone will indicate that the called
zone is being signaled. After the tone, proceed with
the page. If using the talkback control unit, called
party may answer handsfree. If speaker cancel is
wired, when called party goes off-hook, speaker will
be turned off.
To re-ring the same station, press the "*" button. The
station will be signaled as long as the "*" is pressed.
Personal signaling: When initiating a call, press the
"*" and then the station number. A double tone will
be sent to the called speaker. No voice announce or
talkback will be possible.
To dial a new number (tone dial only), press the "#"
button. The speaker for the first number will be
disconnected and dial tone returned to calling party.
Dial new number and page.
NOTE: If "#" is pressed after the speakers have been
inhibited additional numbers may still be dialed. A
tone will signal the called party but no voice
announce or talkback will be possible.
To achieve maximum performance fro m this system,
the user should receive the following operating
instructions:
a.The calling party should speak directly into
the telephone mouthpiece and avoid
speaking too softly.
b.The called party must wait (approximately
1/2 second) before responding to the calling
party.
CIRCUIT DESCRIPTION
General Method of Operation
This unit provides dial intercom access to interface
with the telephone system being used. A one-way
(V-119RTVA) or two-way (V-119RTHF) amplifier
conditions the speech from the telephone system tip
and ring, and provides a low impedance, low level
output to the desired speaker via conventional
telephone wiring, i.e. house cable or station wire.
Detailed Description
When a station user lifts handset to make an ICM
page, the switchhook contacts in the telephone close
the tip and ring to form a loop which returns battery
back to turn on a transistor which operates relay and
logic circuit to return dial tone and lamp battery to
telephone set. Logic circuit receives dialing
information and operates relays and circuitry to
supply splash tone and voice connection for station
selected. When called or any other party goes
off-hook on ICM path, the prese nce of two resistance
grounds cancels or turns off speakers if inhibit
resistors are wired. "Handsfree mode" can only be
restored by terminating call and redialing 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, the test equipment listed below
shall be required:
• Volt-ohm-multimeter
• Tone-dial single line instrument (for tone dial
systems)
• Telephone test set
• Clip leads
Test lamps must not be used to check voltages. They
can damage electronic circuits. When a hand test set
is used to check voltages, the results will be
misleading.
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 the trouble has not been located, refer to Table 1.
This chart identifies symptoms of some possible
problems and solutions.
If a spare unit is available, continue to troubleshoot
by substituting the spare unit for the specified unit.
If, after all the required test have been performed, the
trouble still exists, assistance in troubleshooting is
available from the factory. When calling, you should
have a VOM, a telephone test set and several slip
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 24-hour Automated
Support or visit our website at
