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).
INSTALLATION
The V-9970 Page Control must be powered by a Class
2 Listed, -12VDC output transformer or by -24VDC
NEC Class 2 power source.
When using this equipment, basic safety precautions
should be followed to reduce the risk of fire, electric
shock and injury to persons:
1.
Never install telephone wiring during a
lightning storm.
2.
Never install telephone jacks in wet locations
unless the jack is specifically designed for
wet locations.
3.
Never touch uninsulated telephone wires or
terminals unless the telephone line has been
disconnected at the network.
4.
Use caution when installing or modifying
telephone lines.
Mounting/Connections
1.
Remove the metal mounting plate from the
rear of the V-9970 enclosure. Using two #6
3/4" wood screws, mount the plate in a
vacant space on the backboard with the
telephone system common equipment.
Both
mounting holes must be utilized to insure
secure mounting of the unit.
2.
Open the V-9970 enclosure to allow access
to connections and option switches. Slide
the rear of the unit (Contains the board) onto
the mounting plate.
3.
Using a 1/8" blade screwdriver, connect Tip
and Ring from the Valcom amplified speakers
to PAGE OUT on the V-9970 screw terminals.
4.
Attach two wires from a music source output
to the terminal screws labeled SIG MUSIC
and COM IN. Volume is adjusted by rotating
R13 clockwise.
5.
A 1 Amp internal relay input is supplied to
provide user page notification. Attach two
wires from the notification equipment to the
V-9970 if this feature is to be used.
6.
Plug the RJ11C jack from a single line phone
to connector J2 on the V-9970.
7.
Connect 12V power supply (VP-412A) to
connector J1 (If using the 24V option,
connect the power supply to the terminals
marked COM and 24V).
8.
Set dip switches for desired options. (See
chart following for settings).
Note: Dip switches for user options should be set for
desired functions prior to replacing the enclosure
cover and plugging in the power supply.
9.
Replace cover and plug in power supply.
