V-9956

HANDSFREE TALKBACK PLUG-IN BOARD

INTRODUCTION

The V-9956 Handsfree Talkback Plug-In Board,
designed to be used with the V-2006A, allows
the V-2006A to be converted to a V-2006AHF to
permit handsfree operation.
These instructions contain the specifications and
information necessary to install and operate the
V-9956 used in conjunction with the V-2006A.

DIMENSIONS/WEIGHT

• 9.8” H x 4.5” W x 1.75” D
(24.89cm H x 11.43cm W x 4.44cm D)

• 1.5 lbs (0.68 kg)

Do not connect amplified speakers to the V-9956
talkback zones as they are already amplified.

CONNECTIONS

The V-9956 can be purchased as an "add on"
feature after the initial purchase of a V-2006A.
By adding a V-9956 Handsfree Talkback Plug-In
Board, the V-2006A unit can be modified to a
V-2006AHF.

The V-2006AHF is programmable on a per zone
basis for one-way or talkback communication.
When using talkback speakers, the zone must
be programmed for talkback communication. A
single zone may have both one-way or talkback
speakers. One-way amplified speakers should
be connected to the low-level outputs for zone 1
(W-S pair), zone 2 (R-O pair), zone 3 (R-BR
pair), zone 4 (BK-BL pair), zone 5 (BK-G pair)
and zone 6 (BK-S pair). These speakers will act
as one-way speakers for its 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 page volume control
located on the V-9956 board regulates the
volume of the 45 Ohm talkback speakers under
these circumstances and also provides volume
adjustment of talkback speakers during group
call. The All Call volume adjustment controls the
volume of talkback speakers during all call.

When using Talkback speakers, the zone must be
programmed for Talkback communication.

__ 1. Unplug the V-2006A from the AC power

source; unplug the battery backup if one
is used.

__ 2. Remove the cover of the V-2006A unit

by first removing the 6-32 screws that
attach the cover to the base.

__ 3. Remove the jumper on the V-2006A to

allow handsfree operation. Refer to
Figure 1 for location of the jumper.

__ 4. Plug the V-9956 board into the chassis

of the V-2006A as shown in Figure 2.
Insure the proper alignment of all pins
for proper fit and operation.

__ 5. Secure the V-9956 board to the

V-2006A chassis using the two (2)
screws and washers provided.

__ 6. Insert the Phone to Speaker and

Speaker to Phone volume controls into
the cover of the V-2006A 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.

__ 7. Replace the cover of the V-2006A unit,

insert the 6-32 screws and tighten
snugly to hold in place.

__ 8. Affix the enclosed label to the side of the

V-2006A unit to make certain the
controls relative to the V-9956 are
identified.

__ 9. Using twisted pair telephone wire,

connect the talkback speakers to the
appropriate output (see Figure 3) on the
V-2006A connection block. Zone 1
speakers connect to the Y-O pair, Zone
2 speakers connect to the Y-G pair,
Zone 3 speakers connect to the Y-BR
pair, Zone 4 speakers connect to the
Y-S pair, Zone 5 speakers connect to
the V-BL pair, and Zone 6 speakers to
the V-O pair. No more than two (2) 45
Ohm speakers should be connected to
any talkback zone.

Do not use 8 Ohm speakers.

__ 10. Restore power to the V-2006A, access

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

__ 11. When using talkback speakers, the zone

must be programmed for talkback
communication. Refer to the V-2006A
VSP for programming instructions.
