The speakers may be any Valcom amplified
speaker or horn. The quantity of speakers
required depends on several factures including
the type of speaker and the environment it will be
used in. Please refer to the Installation section of
this document for details.

Power unit requirements for all Valcom speakers
are listed with each speaker model on the Valcom
website. Please refer to www.valcom.com for
specific power requirements for each style of
speaker.

Valcom Power Units

Each page control/interface, speaker and
peripheral device has been assigned a Valcom
power unit (VPU) value. Products that provide
power, such as the 2000 Series page
control/interfaces or power supplies, have power
unit values indicated with a plus (+) sign.
Products that consume power have power unit
values indicated with a minus (-) sign. Products
that neither require nor provide power are
indicated by a VPU of zero (0).

After you have chosen the page control interface,
speakers and accessories for your application,
simply add up all of the Valcom power units
[indicated by a minus (-)] for each item that
requires power. This total tells you how much
power you need. If you have chosen a 2000
Series control/interface, subtract the total power
units provided by this controller from your
previous total. If you come out even, or you have
power left over, you paging system is complete.
However, if you come out with more VPUs
required than provided, you will need additional
power. The additional power required will be
provided by adding one or more VALCOM power
supplies as listed in Table 2.

There are several cases when more than one
power supply will be required:

1. When the power required exceed the
maximum output of the power supplies
available: Add additional supplies as
required.

2. In large systems or systems with many horn
speakers: Locate separate power supplies
near groups of speakers. (Refer to Table 6
for guidelines concerning maximum allowable
distances for power runs.)

3. When the paging system is in several
buildings or on several floors of a single
building, locate power supply in each building
or on each floor being paged.

Valcom V-1094A, V-2000A or V-2001A control
units may be used for page port access to Valcom
paging. Each of these units provide one zone of
one-way paging. If more than one page port is
available a V-1094A, V-2000A or V-2001A may be
used on each port for multizone paging. For help
in speaker and power supply selection refer to
Tables 2 and 3, and to the section titled "1A2,
Dedicated Single Line Set, E-Key, or PABX
Paging".

NOTE: Generally, Valcom dial select
multizone page units may not be used on page
port output. (The V-2003A and V-2006A may be
used on certain page ports that have an
associated page port contact closure and
support DTMF signaling).

Station level Paging

The Valcom V-9940 and V-9970 Station level
Page Adapters may be utilized to provide access
to a single or multiple zone paging system via an
incoming central office line, Centrex//Essex line or
PABX station.

This device:

1) Accepts a ringing phone line or station port.

2) Answers that line.

3) Provides line level audio to the paging
system.

For a single zone of paging, Valcom One-way
Amplified Speakers may be directly connected to
the audio output of the station level page adapter.

Electrically, station level page adapters act
like a "self-answering" telephone.

The V-9940 and V-9970 are FCC registered for
direct connection to the public telephone network,
and also carry U.L. 1459 approval. It will ring trip
from 70 to 105 VRMS (20 to 30 hertz) ringing
voltage.

With a single line telephone, the called party
provides disconnect at the end of the
conversation by going "on hook". A station level
page adapter, on the other hand, has no way of
"knowing" when the calling party has finished
speaking. This unit has to sense line conditions in
order to determine when it is time to disconnect.

4 947100

With the V-9940 and V-9970, this line condition
may be quiet line sensing, a strict "time out"
(disconnects after a selected period of time) or
open loop disconnect of at least 150 milliseconds.
Open loop is a service provided by the central
telephone office and involves actually
disconnecting the telephone line from the C. O.
for a brief instant. In some cases the "quiet line"
may also be programmed via the PABX. "Quiet
line" implies that the PABX will not return any
tones (dial tone, busy tone, and reorder tone . . .
etc.) to the called station at the completion of the
station to station call. The telephone system may
be tested for a "no returned tones" status with
your test set; have someone call you on a station
and then ask them to hang up . . . if you do not
hear any tones, or if there is a delay of at least 10
seconds before you hear any tones, then the
"quiet line" (i.e. audio sense time-out) may be
used.

Ground start telephone lines are a good choice for
use with the V-9940 since a ground start line will
not return dial tone until a ground is applied to the
ring lead.

Additionally, the V-9970 recognizes re-order tones
and dial tone as disconnect signals.

The V-9940 can be used alone, or can provide
access to Valcom multi-zone and talkback page
control units.

The V-9970 may be used to access the V-2003A
and V-2006A multi-zone control units only. The
V-9970 is not compatible with any talkback page
control units.

SYSTEM INSTALLATION

General

These instructions will provide a basic
understanding for wiring Valcom one-way paging
equipment and connecting it to a telephone
system.

For specific wiring information, consult the
installation practice enclosed with the actual
equipment being used.

Precautions

Do not locate Valcom equipment or cabling within
18" of a power supply, electrical panel, or any
equipment that generates electrical noise.

Mounting

The control equipment should be installed at the
main distribution frame with the telephone system
common equipment.

The V-1109RTVA, may be mounted to the
backboard, in a 7" KTU rack or mounting frames.
A 66-type block and 25-pair pigtail with female
amphenol connector, are required for connections
to these units if the mounting frames are not used.
Other control units are wall mount units with
connections via either screw terminals, integrated
punch down block, or a user supplied 66-type
block.

Speaker Spacing

Ceiling Speakers:

The area covered by a ceiling speaker depends
on the height of the ceiling. Refer to Table 3 for
speaker coverage.

Wall Speakers:
A wall speaker will cover up to 600 square feet.
Wall speakers should be spaced 20 feet apart.
Good quality paging will be heard up to 30 ft. in
front of the speaker.

Corridor Speakers:
Corridor speakers should be mounted 8 to 12 feet
high and spaced 30 to 40 feet apart.

Horn Speakers:
Refer to Table 4 for horn speaker coverage. The
first figure given is the side to side distance
between the speakers. It is also the distance in
front of the speaker that you can expect to hear a
good quality page. The second figure given is the
area being covered in square feet.

5 947100

Track Style Speakers:

The 1 watt version will cover an area up to 600
sq. feet. These speakers should be spaced
approximately 20 feet apart. Good quality page
audio will be heard up to 30 feet in front of the
speaker.

The 5 watt version will cover up to 3,600 sq. feet.
Depending upon the height of the installed
speaker, good quality paging will be heard up to
60 ft. in front of the speaker.

Pendant Speaker:

The area covered by a pendant speaker is
determined by the mounting height. Refer to
Table 3 & 4 for speaker coverage.

Very Noisy: Greater than 90dB. This would
include areas where talking to another person is
very difficult. Workers may be required to wear
earplugs.

NOTE 1: In areas where the sound level

exceeds 100dB, consideration should
be given to using a code call unit
(V-9923B) for tone signaling instead
of using voice paging. In extreme
ambient noise, it is generally easier to
identify a tone code than to discern
speech.

NOTE 2: Reverberant Areas - To increase the

intelligibility of paging in reverberant
areas, horns should be mounted
closer to the people being paged, in
effect, mounted at a lower height,
closer together and angled towards
the floor.

Speaker Cabling

All Valcom one-way amplified speakers
require 2 pairs to operate. Standard CAT
3/5/5E/6 telecom/ data cable may be used.
Existing telephone wire and feed cables may
also be used. Refer to Tables 5 and 6 when
planning a job.

Audio pair: The number of speakers looped
on the audio pair is not critical unless you
have a very large job. Table 5 gives guidelines
for the number of speakers per audio run.

Power Pair: The cable runs specified in Table
6 are very important and MUST be followed for
proper operation of the one-way paging
speakers.

Bridges and Backboxes

Ceiling speaker bridges provide support to
prevent ceiling tile from sagging from the weight of
the speaker. They are designed for use with
standard 2' wide ceiling tiles and distribute the
weight of the speaker assembly across the tile
and onto the tile support grid.

Ceiling speaker backboxes provide an acoustic
enclosure behind the speaker for better sound
quality. They also protect the speaker from debris
in the ceiling and meet most local fire codes for
use in air plenum return ceilings. See Table 9 for
Speaker and Bridge/Backbox compatibility.

Volume Adjustments

Master volume controls are located on most
Valcom page control units. Each one-way
speaker assembly also has its own volume
control. When installing a system, set the master
control to ½, and all speaker and horn volume
controls to 1/2 volume. After powering up the
system, adjust the individual speakers to the
desired level.

The master control may then be used to change
the volume of the entire system. If background
music is being supplied, the background music
level should be adjusted last. To provide volume
control to a certain room or area, V-1092 or
V-2992-W Wall Mount Volume Controls may be
added to a zone, or to a section of a zone.

SYSTEM OPERATION
Circuit Description

Each Valcom page control unit contains the
circuitry required to interface with a telephone
system, plus a preamplifier circuit, and in some
cases dial select circuitry and/or provisions for
background music switching. Each one-way
amplified speaker assembly contains a speaker,
amplifier, and volume control in a suitable baffle or
housing. The speakers and control units require a

-24VDC power supply (-48VDC for the V-1038) to
operate.

Connections from the control unit to the telephone
system are described in detail in the manual that
is shipped with the control unit.

The audio pair from the control unit to the
speakers may be looped (speakers wired in
parallel) between all speakers in a zone (See
Table 5). A second pair must be run to each
speaker to supply the DC voltage required for
operation (See Table 6). Standard 22 or 24AWG
telephone cable may be used for the speakers.

When accessing a single zone control unit from
the telephone system, you will immediately be
connected to the speakers and allowed to page.

When accessing a multizone control unit from the
telephone system, you will receive Valcom dial
tone from the Valcom unit. After dialing the code
for the zone desired, you will be connected to that
group of speakers and allowed to page. All
Valcom control units automatically release when
you hang up the telephone.

PROBLEM SOLVERS
Automatic Volume Control

The V-9933A Noise Sensing Volume Control
monitors the noise level fluctuations in an area by
utilizing a built-in microphone. When a page is
made, the V-9933A electronically locks onto the
last noise level sampled and automatically adjust
the volume of up to 150 Valcom One-Way
Self-Amplified Speakers in order to compensate
for the current ambient noise level, thus
eliminating the need for personnel to manually
adjust the paging speakers. The V-9933A should
be mounted in the area that experiences the
fluctuating noise. If a single zone contains areas
of independently fluctuating noise levels, multiple
V-9933A units may be used (one per area).
 Each Noise Sensing Volume Control, V-

9933A, can control up to 150 amplified
speakers or horns in a single zone.

 Multiple Noise Sensing Volume Controls,

V-9933A, can be used on the same zone if
desired.

 V-9933A can be connected to a zone output

of any Valcom One-Way Page
Control/Interface or Station Level Page
Control.

 Not for use with background music

Remote Microphone

The V-9934 Remote Microphone may be used
with the V-9933A Noise Sensing Volume Control.
 V-9934 is a self-contained microphone and

pre-amp.

 No power supply is required for V-9934
 Up to four v-9934 units may be paralleled on

one V-9933A.

 Each V-9934 may be on a 1000’ wire run.

Stacking Feedback Eliminator

The V-9964, Stacking Feedback Eliminator, is
designed to prevent paging system feedback.
When a page is made, the V-9964 records the
page into digital memory. Upon completion of the
live page, the message is released to play over
the speakers. Since the paging party has hung
up the telephone or released the microphone,
offensive feedback cannot occur.
 The Stacking Feedback Eliminator, V-9964,

can control up to 150 amplified speakers or
horns in a single zone.

 The Stacking Feedback Eliminator, V-9964,

can be used with multiple zone page controls.

 Up to four V-9964 Stacking Feedback

Eliminators can be chained together to
provide up to eight page inputs.

ENHANCEMENT TO EXISTING
25/70/100 VOLT PAGING
SYSTEMS

Using a Valcom Page Control/Interface
with a Central Amplifier

Typically a zone from a one-way control unit may
be directly connected to a high power amplifier to
allow access to existing paging equipment. In
certain cases capacitors or a resistor network may
be required to interface the Valcom equipment to
the amplifier. Contact Valcom Technical Support
if trouble is encountered.

NOTE: Not all Valcom page control units have
control leads available for amplifier control.
Use Valcom One-Way Self-Amplified Speakers
to expand a 25/70/100V audio zone.

Using Valcom One-Way Self-Amplified Speakers
to expand a 25/70/100V Audio Zone, it is cost
effective to expand a centrally amplified paging
system with Valcom distributed amplified
speakers. In many instances expanding a
centrally amplified paging system involves
replacement of the expensive central amplifier
with a larger one in order to provide the additional
power that the speakers or horns require.

This also involves additional labor in re-balancing
the system. Adding high voltage type speakers to
an existing amplifier where the load is not
configured properly will cause distortion or
premature system failure, again requiring
replacement of the central amplifier. By using
Valcom distributed amplified speakers to expand
the system, almost unlimited growth is possible,
without loading down the existing amplifier.
Figure 2 shows use of a V-1095 to Volt Expander
to add on to an existing 70 Volt system.

ADVANTAGES OF DISTRIBUTED AMPLIFIED SYSTEMS

 Low voltage, therefore existing telephone cable (Class 2 wiring) can be used to eliminate costly

outside plant or indoor conduit.

 Low voltage operation means much less power dissipation (heat), therefore the longevity of the

paging equipment is increased dramatically.

 Multizone capability of 96 zones from a single trunk port. (Up to 576 Zones with All Call with multiple

systems connected for Global All Call – Call Valcom Technical Support for assistance)

 Talkback, one-way or combination systems are easy to configure.
 Individual volume controls built-in to each one-way speaker for volume adjustment after system is

installed.

 It is cost-effective to install one telephone cable versus installing both telephone cable and 70 volt

shielded paging cable.

 Unlimited one-way speaker expansion since each speaker is self-amplified.
 Jobs requiring explosion-proof systems are easily accommodated.
 Amplified one-way speakers can interface 70 volt systems without changing or adding central

amplifier.

 Many localities require conduit for "high voltage" (Class 1) conductors, this is rarely a necessity with a

distributed amplified system.

 The rated output of a distributed amplified paging speaker or horn is always available due to the fact

that the actual audio signal amplification is accomplished on an individual basis. In a 70 volt system,
the rated output is only available if the central amplifier is actually providing a full 70 volts to the
speaker or horn and the audio signal line losses are negligible.

 Background music is unaffected in zones that are not currently being paged.
