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)
