DESIGN
General
The Valcom V-1101A One-Zone One-way Page
Adapter is designed to provide access to paging from
a standard PABX loop trunk port, an electronic key
system or 1A2 key system C. O. line button, or a 1A2
key system intercom number. In some cases, access
is also possible from a PABX or electronic key
system page port.
REMEMBER: All Valcom paging systems are made
up of three basic components: a page control unit,
speakers, and a power supply.
When one-way amplified speaker assemblies are
specified in this manual, consult your Valcom catalog
for the styles available. Once the style and quantity
of speakers is determined, select the appropriate
power supply after referring to the Valcom One-way
Paging manual or the Valcom catalog.
In addition to the parts listed in each of the following
sections, you will need a 66B type punch down block
and a 25-pair cable with a female amphenol
connector. These may be purchased from Valcom as a
unit with the cable and block already connected and
installed on a mounting frame (part # VM-101).
• (1) V-1101A One Zone One-way Page Adapter
• Valcom one-way amplified speaker assemblies
(quantity and style determined by specific
installation)
• A –24 Vdc power supply if the existing key
system supply is not adequate (the power
requirements are determined by number and style
of speakers)
NOTE: A C.O. line card is NOT required in this
application.
Operation: Press the appropriate line button. You
will immediately be connected to the paging speakers.
Make announcement. The V-1101A will
automatically disconnect when you hang up.
1A2 Intercom Access
When accessing the V-1101A from a bell/ buzzer
intercom connected to a 1A2 key system, the
following equipment will be required:
• (1) V-1101A One Zone One-way Page Adapter
• (1) Unused intercom number
• Valcom one-way amplified speaker assemblies
(quantity and style determined by specific
installation)
• A –24 Vdc power supply if the existing key
system supply is not adequate (power
requirements are determined by number and style
of speakers)
2 947101
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 que s tions
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
These instructions cover the installation procedures
for the Valcom V-1101A and any associated
equipment. Please consult practices for other
manufacturer's equipment if any other equipment is
