4. Attach two wires from a music source output
DESIGN
The Valcom V -9970 is designed to provide paging
access from a standard analog PABX station number,
a C. O. line or analog Centrex line. The Page Control
incorporates the latest technology Digital Signal
Processor (DSP) to recognize and transfer speech
only, thus eliminating unwanted noises such as pops
and tones. A discriminating Automatic Gain Control
(AGC) is provided to make quiet pages louder and
loud pages quieter.
The Single Zone One-way Station Level Page Control
provides a music input with volume control for
background music and an additional 1 Amp internal
relay output (This input closes during a page to
provide user page notification if desired).

DIP SWITCH TERMINOLOGY
The word "default" refers to the factory dip switch
setting. Dip switches 2, 5 and 8 are set "ON" at the
factory enabling silence timeout, dial tone disconnect
and loop detect enable. The pager will "disconnect"
after a page is made when the caller places the
receiver on-hook thus dropping the current loop
(Loop detect) OR by dial tone if the current loop
detect is not passed through the telephone switching
system (Dial tone disconnect) OR if silence is
detected on the line for 4 seconds (Silence timeout).
Dip switch 1 OFF, "Silence Timeout Enable" means
the Page Adapter will hang up when the caller does
not speak for a period of time as selected by dip
switches 3 through 7 (Dip switch 5 is default set to 4
seconds). Note the times can be added on the dip
TIMING OPTIONS
switch settings. If dip switches 3 through 7 are set to
OFF for no timeout, dip switch 1 has no effect and the
timeout option does not occur. Dip switch 1 is
default set to "OFF".
Dip switch 1 ON, "Absolute Timeout Enable" means
the Page Adapter will hang up after a period of time as
set by dip switches 3 through 7 regardless of silence
from the person paging.
Loop Detect is factory set to the default setting of ON
or enable which causes the V -9970 to "hang-up"
when loop current is no longer detected signifying
that the caller has hung-up. Sometimes the local
telephone switch internal to the building does not
pass this signal and then it becomes necessary to
utilize other disconnect options.
