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.
INSTALLATION
General
