Telephone Systems. In accordance with FCC Rules
with applicable tariffs, this Paging Unit may 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, BAF9I7-69358-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 Paging Unit is
installed.

DESIGN

These horns are designed for marine use and can be
used for interior or exterior paging applications. They
are enclosed in a white, no fade, high impact, sealed
plastic housing. They are fully adjustable 360 degrees
horizontal and 90 degrees vertical. They are supplied
with stainless steel hardware and a beam mount clamp.

Applications of the V-1030M and
V-1036M

• Use with Valcom page control

• Expanding the capability of telephone systems

which contain limited paging capabilities

• Loud ringer application in systems where

loud-speaker tone signaling is employed.

Example: In a quiet environment, V-1030M 5 Watt
horns would be spaced 110 feet apart side to side and
would provide good quality sound 110 feet in front of
each horn approximately 12,000 sq. ft. of coverage.

Definitions:

Quiet: 50-65dB. This would include stock areas, etc.

Moderate: 65-80dB. This includes areas such as

warehouses, shipping areas or light manufacturing.

Noisy: 80-90dB. This includes machine shops or
heavy manufacturing.

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

Audio Wire Runs (V-1030M/V-1036M)

When a remote power unit is used, the audio pair run
should be limited to 5000 feet and a maximum of 4
horns when using 24AWG wire. A V-1094A may be
added to increase the number of horns and/or distance.
Twisted pair wire (standard telephone wire) should be
used for connections.

Power Wire Run (V-1030M/V-1036M)

For good quality sound, the distance recommended
between the power supply and horns should be adhered
to.

CONNECTIONS FOR THE

Application

The V-1048M talkback horn is designed to be used
with "handsfree" talkback control units. In combination
with these units, the speaker provides both loudspeaker
and talkback functions.

A standard talkback paging system is comprised of
three basic components:

1. Talkback page control unit

2. Speakers

3. Power Supply

2

Consult your Valcom distributor for assistance in
selecting a control unit and power supply.

Nominal Specifications for the
V-1048M

• Input Impedance: 45 Ohm

Limitations of the V-1048M

• Two talkback speakers maximum per zone.

• 800 feet maximum cable length to speaker

NOTE: Do not split pairs to speakers.

• Do not use talkback in noisy areas (80dB or

greater).

Coverage of the V-1048M

The distance you can be away from a speaker and still
have good talkback depends on the type of speaker and
ambient noise level.

The speaker should be as close as possible to the area
where talkback is desired. It should not be mounted
close to, or pointed at, noise producing equipment such
as fans, air conditioners, machinery, or compressors.

The chart to the right shows maximum talkback
distances relative to the noise level of the surroundings.

Remember: The speaker is no better than
your ears. If you can not carry on a
conversation at normal voice levels over the
required talkback distance, then talkback
page equipment will not function
satisfactorily.

Cabling for the V-1048M

Connections should be accomplished using regular
twisted pair wiring. Do not split pairs.

MOUNTING OF HORN

(All Models)
Attaching Speaker to Base

NOTE: For ease of installation, the base can be
attached to the speaker before or after the base is
mounted.

• Loosen position adjustment knob.

• Insert the ball of the base into the socket of the

speaker.

• Tighten the position adjustment knob.

Mounting

Mount the horn to a suitable surface using the hardware
provided. These units can be mounted to a wall, a
beam or an electrical box.

• Mount the base to a wall using the two holes

provided. Knockout holes are provided for punch
out should additional holes be desired.

• A "C" clamp is provided with the horns to allow

mounting to a beam. Place the bolt through the
hole in the bottom of the base to secure the "C"
clamp to the beam (See Figure 1). It is suggested
that the horn be mounted to the underside of the "I"
beam to provide maximum positioning
adjustments.

• Connection to an electrical backbox is

accomplished by channeling wire through the ball
of the base and making appropriate connections.
The base has holes punched for a double-gang
square box, but by punching out additional
knockout holes, the base can be mounted to a
single-gang or octagon box. (See Figure 2).

The horns may be rotated or moved up and down to
obtain the desired position by loosening the knob at the
bottom of the unit (see both figures) approximately 1
turn. Make required adjustments and re-tighten knob.
