DESIGN
A
The V-1039A may be used to provide one-way
paging from any Valcom one-way or talkback
page control unit. A standard Valcom paging
system (see Figure 1) is made of three basic
components:
1. A page control unit
2. Speakers (such as the V-1039A)
3. A power supply
Consult the Valcom VSP, One-Way Paging, for
detailed information on selecting the control unit
and power supply for one-way paging.

Special Applications
The V-1039A may be connected directly to the
speaker in most electronic key telephones to
amplify the level of the speaker and broadcast it
to a large area. A power supply will also be
required.
The V-1039A may be used to expand a 70 volt
type paging system without placing an additional
load on the amplifier by connecting the speaker
directly to the 1/4 watt output of one of the
existing 70 volt transformers. A power supply is
also required.
Coverage
Refer to the table below for coverage of this horn
assembly. The first figure given is the side to
side distance to use when mounting the horns. It
is also the distance in front of the horn that you
can expect to hear a good quality page. The
second figure is the total square footage the horn
assembly will cover.

INSTALLATION
Cautions
The V-1092 volume control is NOT designed for
areas requiring explosion proof equipment.
When installing this system, do not mount the
V-1092 volume control in the hazardous
environment.
To prevent ignition in a hazardous atmosphere,
disconnect product from supply circuit before
opening. Keep assembly tightly closed when in
operation. Unit must be installed in accordance
with the national Electrical Code requirements
for hazardous atmospheres.
Should it be necessary to remove the back cover
of the explosion proof driver enclosure, be
certain to exercise special care to avoid
damaging machined surfaces. Prior to
reassembly, make certain that adjoining surfaces
of enclosure are free from dirt. Tighten all bolts
completely. To provide the specified protection
in hazardous locations, please note that no
compound of any type is to be applied to the
machined flange. Care must be taken to ensure
no wires are captured between these machined
surfaces.
Connections
Four conductor wire is required for the V-1039A.
Standard 22 or 24 gauge station wire is
acceptable. Shielded wire is not required or
recommended. Connections are as follows:
Brown Tip/A
Red Ring/B
Black Ground
White -24 VDC
Tip and Ring are connected to Tip Out and Ring
Out of the V-1092 volume control. Tip In and
Ring In of the volume control must be connected
to the output of the page control unit. The –24
VDC and ground leads connect directly to the
power supply. See Figure 2.
The Specifications in Tables 1 and 2 must be
met when wiring this speaker assembly.
