DESIGN

The Valcom Dual Input One-Way Amplified Interior

Speakers may be used to provide one-way paging

from one-way or talkback page controls. The

speakers provide a means for connecting one speaker

to two audio sources, making it easy to provide

features such as background music, group call, or

emergency override. These speakers can also be used

to expand existing 70V paging systems. When power

and the appropriate input signal are applied, voice

page can be made.

Page Control Access

When using the One-Way Amplified Speakers with a

Page Control, the following equipment will be

required:

• Appropriate one-way speaker assembly

• Page Control

• Power Supply sized to provide power to

operate the amplified speaker

assemblies and page control. (See

Figure 1 for Page System Block

Diagram)

NOTE: When using Valcom Dual Input One-Way

Interior Speakers with a handsfree page control, it is

recommended that a V-1092 Volume Control be

connected between the zone output and the speaker

input to lower the signal level to the one-way

speakers (to prevent overdriving of inputs).

25V or 70V Paging Systems

When using the One-Way Amplified Speakers with

an existing 25 or 70V paging system, the following

equipment will be required:

• Appropriate one-way speaker assembly

• Power supply sized to provide power to

operate the amplified speaker

assemblies

• 25V or 70V line transformer tapped at

1/4 watt with an 8 Ohm output

Background Music

The Valcom Dual Input One-Way Amplified

Speakers may be used with a page control for the

purpose of providing background music on a per zone

basis along with one-way voice paging (See Figure 2

for a Background Music Block Diagram).

NOTE: When using the Dual Input One-Way

Amplified Speakers with background music and a

handsfree page control unit, it is recommended that a

V-1094A Page Port Preamp/Expander be connected

between the zone output and the speaker input to

eliminate backfeed of the background music to the

handsfree control unit.

control, it is recommended that a V-1092 Volume

Control be connected between the zone output and

the speaker input to lower the signal level to the

one-way speakers (to prevent overdriving of inputs).

Speaker Cabling

All Valcom Dual Input Amplified One-Way Interior

Speakers require six conductor wire, standard 22 or

24 gauge station wire is acceptable. Shielded wire is

not required or recommended. Refer to Tables 1 and

2 when planning a system.

Coverage

V-1220 - Ceiling Speaker: The area covered by a

ceiling speaker is determined by the height of the

ceiling. If the ceiling height is 8', the speaker will

cover approximately 250 sq. ft.; if 9 to 15', the

speaker will cover approximately 400 sq. ft.; if 15 to

35' high, the speaker will cover approximately 850 sq.

ft.

V-1222C, V-1224C - Wall Speakers: These wall

speakers will cover an area up to 600 sq. ft. Wall

Speakers should be spaced 20 feet apart. Good

quality paging will be heard up to 30 feet in front of

the speaker.

V-1226C - Corridor Speaker: Corridor speakers

should be placed every 30 to 40 feet.

INSTALLATION

Page Control Access

The Valcom Dual Input One-Way Amplified Interior

Speakers provides a means for connecting one

speaker to two audio sources. A standard paging

system is made up of 3 basic components:

• Appropriate one-way speaker assembly

• Page Control

• Power Supply sized to provide power to

operate the amplified speaker

assemblies and page control

NOTE: When using the Valcom Dual Input

One-Way Interior Speakers with a handsfree page

control, it is recommended that a V-1092 Volume

Control be connected between the zone output and

the speaker input to lower the signal level to the

one-way speakers (to prevent overdriving of inputs).

See Figure 4 for Screw Connection Location and

Designations. See Figure 5 for the required

connections when using the Dual Input One-Way

Amplified Interior Speakers with a page control.
