GLOSSARY OF TERMS 16

The V-2924 Talkback Intercom System provides 24 stations with one-way, two-way, group call and all call pages.
Each station can be programmed for one-way or two-way communication. The stations may be grouped into one­way page groups. The system also provides the ability for a remote speaker location equipped with a call button to
call the attendant location. The attendant receives calling speaker identification when using a Caller ID equipped
telephone or a Caller ID display.

The V-2924 is compatible with standard 45 ohm speakers and one-way amplified speakers and can be accessed via a
single line phone, E-Key line port or PABX loop start trunk port. An RS-232 port on the control unit provides a
connection for a serial printer for printout of system activity.

The V-2924 provides a background music input and is designed to automatically mute music during a page. The
basic system also provides four (4) contact closures associated with the last 4 zones to allow for door strike plate
activation. Multiple V-2924 control units can be interconnected to allow global all call and global priority pages for
up to six (6) V-2924 control units.

1 947211

The V-2924 Control Unit provides access to 24 stations. A V-2925 Expansion Unit is available for the V-2924.
Each V-2925 Expansion Unit will increase the capacity of the V-2924 by twenty-four (24) additional stations. Up
to three (3) Expansion Units can be added to a system for a total of 48, 72, or 96 zones of paging.

A V-2926 Plug-in Option Board is also available to provide enhanced Caller ID, flexible architectural numbering,
user defined page groups, a secondary serial port for easier programming and real-time clock. A Windows-based
programming tool is used with the option board to simplify system programming. The tool can be used with PC
compatible computers using the Microsoft Windows operating system.

protected interface devices. Additionally, the host
system must be configured to disallow a central
exchange trunk co nferencing in ord er to prevent
indirect connection to the network.

instruction manual, may cause harmful interference to

3 947211

radio communications. Operation of this equipment
in a residential area is likely to cause harmful
interference in which case the user will be required to
correct the interference at his own expense.

Mounting

The V-2924 was designed for wall mounting only.
Using the enclosed paper template, mark the locations
for the mounting screws on a plywood backboard
(minimum ½” thick). Insert screws and tighten to
within 1/8” of the surface. Hang the unit on the
screws, slide the unit left to the narrow end of the
slots and tighten screws firmly.

Connections

Mount (3) 66B type punchdown blocks on the
backboard near the V-2924 control unit. Make
connections to the punchdown blocks as specified in
Figure 2 - Punchd own Block Connections. (System
Inputs - Block 7, Speaker Outputs - Block P3, Switch
Inputs - Block P6). Also refer to the following
diagrams for connections of each application.

Setting Option Switches

After all connections have been made, set the option
switches to fit the specific user requirements. Refer
to Figure 1 for location and Table 1 for the default
values of the various switche s. Make changes as
required.

Connect cordset to unit via IEC 320 female connector located on one
end of cordset to IEC 320 male applaince coupler located on V-2924.

For 115 VAC use

•

selector switch displays 115 V.

For 230 VAC use

•

selector switch display 230 V.

After all required connections have been made, plug the cordset

•

into appropriate AC wall outlet.

, verify fuse rating of 1 amp and voltage

, verify fuse rating of .5 amp and voltage

For United Kingdom use:

As the colors of the cores in the main lead may not
correspond with the colored markings identifying the
terminals in your plug, proceed as follows:

• The core which is colored green and yellow must

be connected to the terminal in the plug which is
marked with the letter E or by the earth symbol
(inverted Christmas tree), or colored green and
yellow.

• The core which is colored blue must be

connected to the terminal which is marked with
the letter N or colored black.

• The core which is colored brown must be

connected to the terminal which is marked with
the letter L or colored red.

any talkback speaker (this cancels the page to all
other speakers and connects the attendant to the
answering speaker)

speaker included in the original page two times,
the call is disconnected from the active speaker
and reconnected at the new speaker.

• Handsfree alert tone notifies the attendant and

speaker location the Meet Me or Follow Me was
successful.

Inhibit

Allows the use of a single line phone (“A” lead
modified). When the phone goes offhook, all
handsfree, group, and/or all call pages are cancelled
and the phone is connected to the attendant.

Override Page Port

When a phone connected to the override page port
goes offhook, it is immediately connected to all
speakers for a one-way page. Any existing handsfree
or one-way pages will be placed at the top of the
queue for reconnection when the priority phone
releases. The attendant phone receives a repeat beep
tone alerting of an override.

Queue Operation

Attendant phone is in use and another call is placed
from a speaker location, the phone and connected
speakers receive a queued call tone (single or triple
beep tone), and the call is placed in the queue.
Pressing the “#” key twice while on a call with one or
more queued calls, will disconnect the current call
and connect the attendant to the next call in the
queue. If the attendant hangs up while calls are in the
queue, the phone will ring and the next call in the
queue will be connected when the phone is answered.
Queued calls will be accessed in the order received
with a maximum of 20 calls being in the queue at one
time. If the queue is full, additional calls are ignored
unless the last queued call has a lower priority than
the incoming call in which case the lower priority call
will be replaced in the last position by the new call.
