General
The Valcom V-2000A Integrated Single Zone Page
Control Unit provides access to paging from a
standard PABX loop start trunk port, an Electronic
Key System C. O. line button or a 1A2 Key System C.
O. line button (A 400 type line card is required). In
most cases, access is also possible from a PABX or
Electronic Key System page port.
NOTE: Do not connect to Central Office Line or
PBX Station Port.
Electronic Key or PABX Access
When using the V-2000A with an electronic key
system or PABX, the following equipment will be
needed:
1) 1 -V-2000A Integrated Single Zone Page Control
Unit
2) 1 -C. O. Line Circuit (Electronic Key System) or 1
Loop Start Trunk Circuit (PABX)
3) Valcom One-way Amplified Speaker Assemblies
(Quantity and style determined by specific
installation)
Operation: Press the appropriate line key (Electronic
key system) or dial the appropriate trunk access code
(PABX). You will immediately be connected to the
paging speakers. Make announcement. The V-
2000A will automatically disconnect when you hang
up.
Page Port Access
When accessing the V-2000A from a page port the
following equipment will be required:
•One V-2000A Integrated Single Zone Page
Control Unit
•Telephone System Page Card (If required for
external page outputs)
•Valcom One-way Amplified Speaker Assemblies
(Quantity and style determined by specific
installation)
Operation: Follow the telephone manufacturers’
directions on how to access external paging. You will

Mounting
The V-2000A was designed for wall or table mounting.
The intended mounting orientation will render the
text on the enclosure lid legible when the unit is
viewed. When wall mounting this unit, secure it to
wall studs or a suitable brace (A plywood backboard
2' square and at least 1/2" thick attached to wall studs
would be considered a suitable brace). Make certain
the unit is not mounted near heat sources or strong
magnetic fields. Ascertain control and terminal strip
accessibility.
Four #10 x 3/4" cross-tip round head wood screws are
included for mounting. Fasten the top two screws at
the appropriate location on the mounting surface
(Approximately 3.65" apart and parallel to the floor),
allowing the screwheads to protrude 1/8" to 1/4".
Place the chassis of the unit onto the screwheads at
the mounting slots. Position the two remaining
screws and fasten through the remaining mounting
slots. Complete the mounting by tightening all
screws.
Power Connections
The V-2000A is provided with a three-conductor line
cord. After all required connections have been made,
plug the cord set into appropriate AC wall outlet.
Volume Adjustments
Located on the front cover of the V-2000A are the
screwdriver adjustable volume controls for regulating
the page and background music level. Each volume
control is set by turning it clockwise to increase the
volume and counterclockwise to decrease the volume.
__ a. Page Level: During initial system set up, it is
recommended that the individual speaker
volume controls on the amplified speaker
assemblies be adjusted to 1/2 volume first.
Then, adjust the volume control on the
V-2000A to the desired page level.
__ b. Background music level: Adjust this control
to give the desired background music level
on the paging speakers.
Wiring Instructions

Optional Connections
Music Connections -Connect the output of a low
level music source to the screw terminals marked
“Music” on the input terminal strip on the V-2000A.
Adjust the music volume control on the V-2000A to
the appropriate level.
OPERATION
General
When the V-2000A is connected to a C. O. line
position or a loop start trunk port, a Tip and Ring
battery feed is provided when the battery feed switch
is in the "ON" position. The voice switching circuit is
turned on when the person making the page begins to
speak. Background music, if connected, will be
turned off and the persons voice will be present on
the output. The voice switching circuit remains onas
long as the person is speaking. When the page is
completed or the person stops speaking for more than
3 seconds, the paging circuit is turned off and
background music is restored to the output. Note:
When the V-2000A is connected to a telephone
system page port, the battery feed switch should be
in the "OFF" position. The operation of the unit is
the same.
TECHNICAL ASSISTANCE
