V-1109RTVA

NINE ZONE PAGE CONTROL

INTRODUCTION

The V-1109RTVA, Nine Zone Page Control, is a
dial select microprocessor controlled page unit to
be used with PABX, Electronic Key or 1A2
Telephone Equipment.

These instructions contain the specifications and
information necessary to install, operate and
maintain the Nine Zone Page Control.

This paging unit has received an FCC type KX
registration and is designed to be used with FCC
registered key telephone systems. Such
installations may be made by Valcom, Inc.,
Telephone Companies and registered telephone
installers 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 Number BAF9I7-69358­KX-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 generates and uses radio
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
interference. If this equipment 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

If necessary, the user should consult the dealer or
an experienced radio/television technician for
additional suggestions. The user may find the
following booklet prepared by the Federal
Communications Commission helpful: "How to
Identify and Resolve Radio-TV Interference
Problems."

INSTALLATION

This section covers the installation procedures for
the Valcom V-1109RTVA only. Consult other
equipment instructions if additional equipment is
used.

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:

2

• 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 five feet from 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 unit in a vacant space in an equipment
cabinet, rack or key system cabinet, allowing
enough room at the rear of the unit to plug in an
amphenol connector. Mount a 66B type
punchdown block near the unit and label it per
Figure 1.

Cabling

A 25 pair cable with a female connector should be
ran from the unit to the connection block. The
cable should be terminated on the connection
block in standard color code order. Verify that the
connections are correct prior to plugging the other
end of the cable into the V-1109RTVA Page Unit.

Connections to PABX System

The V-1109RTVA may be accessed by
connecting the W/BL and BL/W to the Tip and
Ring respectively of a Loop Start Trunk Circuit.
Refer to Figure 2 for connections.

Connections to Electronic Key
Systems

The V-1109RTVA may be accessed by a C.O.
line position of an Electronic Key System by
connecting the W/BL, BL/W of the V-1109RTVA
to a spare line position of the Electronic Key. This
line position must be equipped with a trunk card.
Refer to Figure 2 for connections.

Connections to 1A2 Key System

The V-1109RTVA may be connected to a spare
button of a 1A2 Key Telephone by making the
following connections: (A 400 type line card is
not needed in this application).

• W/BL, BL/W of V-1109RTVA to spare button
Tip and Ring

• O/W to Lamp Lead of spare button for lamp
connections

• W/GR to Lamp Ground lead of spare button

NOTE: When the V-1109RTVA is connected to
a 1A2 Key System, connect W/O to Lamp

Battery or Ground. See Figure 3.

NOTE: For "Meet Me Page" on 1A2, connect
A-Leads from spare button using 10K Ohm
resistors in series with each A-Lead. The
other side of resistors are connected to the
BK/G (inhibit) of V-1109RTHF. Refer to Figure
3 for connections.

Power Connections

• The V-1109RTVA is designed to use -24VDC
battery.

• Connect the V/BR lead to Talk Ground.

• Connect the BR/V lead to Talk Battery

(-24VDC filtered).

• Connect the V/S lead to Signal Ground.

• Connect the S/V lead to Signal Battery

(-24VDC unfiltered).

Speaker Connections

The outputs for paging zones start at the BK/BR
pair (zone 1) through the V/O pair (zone 9). Refer
to Figure 3 for typical speaker connections using
Valcom one-way amplified speaker assemblies.

Page and Music Level Set-up

The V-1109RTVA has volume controls for the
following functions:

• Master Page Control - located on back of unit
below amphenol connector

• All Call Master Control - located on front of
unit

• Background music input control Zones 1-5

• Background music input control Zones 6-9

Control Set-Up:

1. Master Page Control:

This control sets the level of the page out of
the page control unit. The control should be
rotated clockwise to about 50% of its travel.
After setting control, the individual speaker
volume controls should be set to the desired
level.

2. All Call Level:

The All call level should be set to produce the
same audio level as the phone to speaker
page control. THIS ADJUSTMENT
SHOULD BE MADE AFTER INDIVIDUAL
SPEAKER LEVELS HAVE BEEN SET.

3. Background Music Levels:

There are two volume controls provided for
background music adjustments: Zones 1-5
and Zones 6-9. It is important that the two
background music controls be used to set the
music levels in the system. Adjust these controls
after all other system volume levels have been

3

set. THE MUSIC INPUT LEVEL FROM THE
MUSIC SOURCE SHOULD BE LIMITED TO

0.25VRMS MAXIMUM. A SOURCE LEVEL
GREATER THAN 0.25VRMS WILL RESULT IN
PERMANENT DAMAGE TO THE
BACKGROUND MUSIC AMPLIFIERS
CONTAINED IN THE V-1109RTVA. The music
source should be connected to the V/G Pair on
the connecting block for the Page Control Unit.

OPERATION

This unit provides multi-zone page access
provisions to appropriately interface with the
telephone system being used. A preamplifier
conditions the audio from the telephone system
tip and ring and provides a low impedance low
level output to the desired page zone.

Circuit Description

When a station user lifts his handset to make a
page, the switchhook contacts in the telephone
close the tip and ring to form a loop which returns
battery back to turn on transistor Q1. Transistor
Q1 operates relay and logic circuits to return dial
tone and lamp battery to the telephone set. Logic
circuits receive dialing information and operate
relays and/or circuitry to provide a ringback tone
and a one-way connection for the zone selected.

TECHNICAL ASSISTANCE

When trouble is reported, verify that power is
being supplied to the unit and there are no broken
connections. Be sure that the amphenol is
secure in the back of the unit. Check voltages for
proper polarity on the crossconnect block.
A lineman's test set, several clip leads and a
VOM may be necessary to effectively
troubleshoot the unit.

Table 3 identifies some possible problems and
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 and a telephone test set available and be
calling from the job site. Call [phone] for
Technical Support or visit our website at
http://www.valcom.com.
