A default time is available when using the "open
loop" disconnect on the V-9940 (up to 64 seconds).
An additional feature of the V-9940 Station Level
Page Adapter is that multiple units may be linked
together for a common "all call" (accessed through a
separate "all call" V-9940).
SYSTEM INSTALLATION
General
These instructions will provide a basic understanding
for wiring Valcom one-way paging equipment and
connecting it to a telephone system.
For specific wiring information, consult the
installation practice enclosed with the actual
equipment being used.
Precautions
Do not locate Valcom equipment or cabling within
18" of a power supply, electrical panel, or any
equipment that generates electrical noise.
Mounting
The control equipment should be installed at the main
distribution frame with the telephone system common
equipment.
The V-1101A, V-1109RTVA, V-119RTVA, V-1118,
V-136RTHF and V-1134 may be mounted to the
backboard, in a 7" KTU rack, in a Valcom VM-101,
or mounting frames. A 66-type and 25-pair pigtail
with female amphenol connector are required for
connections to these units if the VM-101 or mounting
frames are not used. Other control units are wall
mount units with connections via either screw
terminals, integrated punch down block, or a user
supplied 66-type block.
Speaker Spacing

speaker depends on the height of
the ceiling. Refer to Table 5 for

600 square feet. Wall speakers
should be spaced 20 feet apart.
Good quality paging will be
heard up to 30 ft. in front of the

Corridor Speakers: Corridor speakers should be
mounted 8 to 12 feet high and
spaced 30 to 40 feet apart.

distance between the speakers.
It is also the distance in front of
the speaker that you can expect
to hear a good quality page.
The second figure given is the
area being covered in square
feet.

to 3,600 sq. feet. Depending
upon the height of the installed
speaker, good quality paging
will be heard up to 60 ft. in front
