output of a zone programmed for talkback to
augment the page output on that zone. (NOTE:
Only talkback speakers are able to receive
reply).
___1. Using twisted pair telephone wire,
connect talkback speakers to the
appropriate output (See Figure 3) on the
V-2003A/V-2003AHF connection block.
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.
___2. Adjust volume controls.
Optional Connections
A. Background Music Connections
Connect the low level (-10 to -18dBm, 8 to 600
Ohms) output of music source to (W/GR) and
(GR/W) terminals of the cross connect block.
Adjust music volume (Page overrides music).
NOTE: Failure to use a low level music source
could cause music crosstalk on zones not
receiving music or damage to the Control Unit.
B. Clock Closure (Single Tone) Connections
Time Clock Contact Closure - (V/G), (G/V).
Time clock signaling will override page.
C. UNA Closure (Warble Tone) Connections
Telephone System Night Answer (Contact
Closure) - (V/BR), (BR/V). This tone will
override music but is overridden by a page.
D. UNA Ringing (Warble Tone) Connections
90VAC Night Answer Ringing - (V/S), (S/V).
These connections will activate a night ring tone.
E. Inhibit Option
If a single line telephone is desired for "meet me
answer," a single line "A" lead control telephone
and a 5.1K Ω resistor is required. This feature is
available only if the unit is accessed through a
trunk port. The T & R of the telephone connects
to the W/BL pair, the "A1" lead connects to GND
(BL/BK), the "A" lead had the 5.1K Ω resistor
placed in series, and the resistor terminates on
inhibit (BR/W). Inhibit is not a feature of override
tip and ring access. Calls currently engaged in
a "meet me answer" are not disturbed during the
override.
F. Override Connections
Telephone System Page Override - (W/S),
(S/W). Page override can be activated by a
vacant C.O. line position, loop start or ground
start trunk, or dedicated single line phone.
Make certain SW1 is in correct position for loop
or ground start mode of operation.
TECHNICAL ASSISTANCE
When trouble is reported, verify that power is
being supplied to the unit and there are no
broken connections. Check voltages for proper
polarity on the crossconnect block. Table 1
identifies symptoms of some possible problems
with solutions. If a spare unit is available,
continue to troubleshoot by substituting the
spare unit for the suspected defective unit.
Assistance in troubleshooting is available from
the factory. When calling, you should have a
VOM, a telephone test set, several clip leads
available and be calling from the job site. Call
(540) 563-2000 and ask for Technical Support
or call (540) 767-1555 for Valcom 24-hour
