NOTE: The intercom used MUST supply a holding ground or page control lead to properly operate the V-1101A. A page control lead is a lead that supplies Ground whenever the intercom is in use, and which is Open when the intercom is idle. Contact the manufacturer of your intercom if you have questions about this lead.
Operation: Press the intercom button and dial the number assigned to the V-1101A. You will then be connected to the paging speakers. Make announcement. The V-1101A will automatically disconnect when you hang up.
Page Port Access
CAUTION: To use the V-1101A on a PABX or electronic key system page port, the telephone system MUST SUPPLY both an audio pair AND a dry contact closure.
When accessing the V-1101A from a page port, the following equipment will be required:
•(1) V-1101A One Zone One-way Page Adapter
•Telephone system page card (if page outputs are not built in)
•Valcom one-way amplified speaker assemblies (quantity and style determined by specific installation)
•A –24 Vdc power supply (size and quantity determined by number and style of speakers)
Operation: Follow the telephone system manufacturer's instructions for accessing paging. Make announcement. The V-1101A will automatically disconnect when you hang up.
Background Music
Background music may be connected to the V-1101A when using any of the above configurations. The background music will automatically cut off when the paging is accessed.
The background music source should have a output impedance of approximately 8 Ohms. An output level of 1 watt will be more than sufficient to drive the amplified speakers. The background music source must have it's own volume control.
The wiring of each arrangement is covered in the next section.
