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)
FIGURE 1 – 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
- V-1095 70 Volt Expander
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.
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. (See Figure 3 for a Group Call Block Diagram).
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).
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-1222 – Wall Speaker: Wall speaker 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.

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.
-
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.
Mounting
-
V-1220 – Ceiling Speaker: To install speaker assembly, measure and cut an 8-1/2″ hole in center of ceiling tile. (If using a V-9914M-5 bridge, V-9915M-5 backbox, or V-9916M bridge and backbox, follow instructions supplied with these assemblies).
Connect station or other suitable wire to proper speaker terminals as labeled. Mount speaker to ceiling tile. Ideal mounting height should be between 7 and 23 feet. -
V-1222 – Wall Speaker: Unscrew the speaker bracket and mount the bracket to the wall (ideal mounting height is 8 to 12 feet above floor level). Connect station or other suitable wire to proper speaker terminals as labeled. Mount speaker on bracket.
