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.
