V-9953

HANDSFREE TALKBACK PLUG-IN BOARD

INTRODUCTION

The V-9953, Handsfree Talkback Plug-In Board,
designed to be used with the V-2003A, allows the
V-2003A to be converted to a V-2003AHF to permit
handsfree operation.

These instructions contain the specifications and
information necessary to install and operate the
V-9953 used in conjunction with the V-2003A.

DIMENSIONS/WEIGHT

• 6.80" H x 4.75" W x 1.50" D

(17.27cm H x 12.07cm W x 3.81cm D)

• 1.0 lbs (.45 kg)

CONNECTIONS

The V-9953 can be purchased as an "add on" feature
after the initial purchase of a V-2003A. By adding a
V-9953, Handsfree Talkback Plug-In Board, the
V-2003A unit can be modified to a V-2003AHF.

The V-2003AHF is programmable on a per zone
basis for one-way or talkback communication. A
single zone may have both one-way and talkback
speakers. One-way speakers should be connected to
the low level outputs for zone 1 (R/BL pair), zone 2
(R/G pair) and zone 3 (R/S pair). These speakers will
act as one-way for the associated zone whether or not
the zone is programmed for one-way or talkback
paging.

If 45 Ohm speakers are connected to the handsfree
output and the zone is programmed for one-way, the
speakers will receive the page. The zone must be
programmed for talkback communication in order to
utilize the talkback option. The page volume control
located on the handsfree board regulates the volume
of the 45 Ohm talkback speakers under both these
circumstances.

Do not connect amplified speakers to the V-9953
talkback zones as they are already amplified.

__ 1. Unplug the V-2003A from the AC power

source; unplug the battery backup if one is
used.

__ 2. Remove the cover of the V-2003A unit by

first removing the four (4) - #32 screws that
attach the cover to the base.

__ 3. Plug the V-9953 board into the chassis of

the V-2003A. Insure the proper alignment
of all pins for proper fit and operation.

__ 4. Secure the V-9953 board to the V-2003A

chassis using the two (2) screws and
lockwashers provided.

__ 5. Insert the Phone-Speaker and Speaker-Phone

volume controls into the cover of the
V-2003A as shown in Figure 2. The control
with the long shaft is Phone to Speaker; the
control with the shorter shaft is Speaker to
Phone. Secure these controls with the
washers and nuts provided.

Make sure the tab on the body of the control
engages the enclosure.

__ 6. Replace the cover of the V-2003A unit.

Insert the four (4) - #32 screws and tighten
snugly to hold in place.

__ 7. Affix the enclosed label to the side of the

1 947210

V-2003A unit to make certain the controls
relative to the V-9953 are identified.

__ 8. Using twisted pair telephone wire, connect

the Talkback Speakers to the appropriate
output on the V-2003A connection block
(Figure 3). Zone 1 speakers connect to the
BK/G pair, Zone 2 speakers connect to the
BK/BR pair , and Zone 3 speakers connect
to the BK/S pair. No more than two (2) 45
Ohm speakers should be connected to any
Talkback zone. Do not use 8 Ohm speakers.

__ 9. Restore power to the V-2003A; access page

and adjust the volume controls as required.
There are separate volume controls for the
Phone to Speaker, Speaker to Phone, Page,
Background Music, and Night Ring/Warble
Tone. For best results, the Speaker to Phone
volume control should be turned as low as
possible to where background music is just
barely audible.

__ 10. When using talkback speakers, the zone

must be set (utilizing the dip switches) for
talkback communication.

dip switch activates/de-activates.
