SYSTEM DESIGN

General

The Valcom V-2000 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.

Electronic Key or PABX Access

When using the V-2000 with an electronic key system
or PABX the following equipment will be needed:

1) 1 - V-2000 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 appr opriate trunk access code
(PABX). You will immediately be connected to the
paging speakers. Make announcement. The V-2000
will automatically disconnect when you hang up.

Page Port Access

When accessing the V-2000 from a page port the
following equipment will be required:

1) 1 - V-2000 Integrated Single Zone Page Control

Unit

2) Telephone system page card (if required for

external page outputs).

3) 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 immediately be connected to the paging speakers.
Make announcement. The V-2000 will automatically
disconnect when you hang up.

Background Music

Background music may be connected to the V-2000
when using any of the above configurations. The
background music will cut off automatically when the
party making the page is speaking.

INSTALLATION

Precautionary Designations

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION: To reduce the risk of electric shock,

Refer servicing to qualified service personnel.

Mounting

The V-2000 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-2000 is provided with a three conductor line
cord. After all required connections have been

made, plug the cordset into appropriate AC wall
outlet.

Volume Adjustments

Located on the front cover of the V-2000 are the
screwdriver adj ustable vo lume control s for regula ting
the page and bac kground music level. Each volume
control is set by turning it clockwise to increase the
volume and counterclockwise to decrease the volume.

Do not remove cover.

No user serviceable parts inside.

This symbol indicates that dangerous
voltage constituting a risk of electric
shock is present within this unit.

This symbol indicates that there are
important operating and maintenance
instructions in the literature accompanying
this unit.

__ 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-2000 to the desired page level.

__ b. Background music level: Adjust this

control to gi ve the desired background music
level on the paging speakers.

Wiring Instructions

(For Electronic Key System Line Button
Access or PABX Loop Start Trunk Access)

NOTE: The telephone system referred to in the
following instructions is the customer premise
equipment such as an electronic key system or a
PABX. The V-2000 CANNOT be connected

directly to a public telephone network (a central
office line).

If a modular cord is used for Tip and Ring
connections start at step ONE. For screw terminal
connections start at step TWO. (See Figure 2).

__ 1. Connect one end of a modular telephone

cord to the V-2000 RJ11 and the other end
to a vacant C. O. line position or vacant loop
start trunk on the customer premise
equipment. Go to step 4.

__ 2. Connect Tip of the vacant key system line

position or PABX loop start trunk to the Tip
screw terminal of the V-2000.

__ 3. Connect Ring of the vacant key system line

__ 5. Connect Ring of the one-way amplified

speakers to the remaining Signal Out screw
terminal on the V-2000.

__ 6. Connect the –24 Vdc terminal or lead of the

one-way amplified speakers to the –24 Vdc
screw terminal of the V-2000.

__ 7. Connect the GND terminal or lead of the

one-way amplified speakers to the GND
screw terminal of the V-2000.

NOTE: The Valcom V-2000 provides external
power of 12 power units (600 mA of –24 Vdc) to
operate Valcom one-way amplified speakers.
Additional power supplies are required for a quantity
of speakers using power over the 12 power units.
When using additional power supplies, make
certain:

appropriate level.

OPERATION

General

When the V-2000 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 on as
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-2000 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
