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.

FIGURE 5
25V or 70V Paging Systems
The Dual Input One-Way Amplified Speakers may be used to expand an existing 25V or 70V paging system without placing an additional load on the amplifier by connecting one input of the speaker directly to the 8 Ohm output of one of the existing 70 Volt transformers tapped at 1/4 watt. A power supply will also be required.
Background Music
The Valcom Dual Input One-Way Amplified Speaker may be used for providing background music on a per zone basis along with one-way voice paging. The music source is connected to Input 2 Tip and Ring. The page zone output is connected to Input 1 Tip and Ring.
NOTE: When using the Dual Input One-Way Amplified Interior 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.
Group Call
The Valcom Dual Input One-Way Amplified Speakers may be used with a multi-zone page control to provide simultaneous paging to a group of zones. When it is used for group call, Input 1 is connected to an assigned zone number. Input 2 is connected to the zone number that will be used for the group call page.
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 Tables 1 and 2 for wiring specifications for these speaker assemblies.
