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.
