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)
