C.O.6
General
The Valcom V-9936A is designed to monitor up to
six C. O. lines or PABX station numbers and will
provide a common tone signal and contact closure
whenever any of the lines are ringing. The V-9936A
may be used with most telephone systems because it
connects directly to the lines and not to the phones.
The tone output may be connected to speakers used
only for ringing, or to one zone of a paging system.
The dry contact closure may be used to activate loud
ringing bells, strobes, or other external equipment.
Both outputs will provide interrupted signals
whenever any line is ringing.

INSTALLATION
A disable input is provided for connection of a night
switch. With no switch connected, the V-9936A
will signal any time a line rings in. With a switch
connected and providing a short across the disable
input, the unit will be inactive.
Stand-Alone Ringing
The following components are required to provide
common audible ringing over dedicated bells or
speakers.
• V-9936A C. O. Ring Units, 1 per 6 lines
• Signaling Devices consisting of:
a. Two 45 Ohm talkback speakers, or
b. Up to 150 one-way amplified speakers, or
c. Loud bells, buzzers, strobes, etc. as required.
• Power Supply: The VP-624B will power a
V-9936A using talkback speakers for signaling.
If one-way speaker assemblies or other signaling
devices are used, additional power may be
required.
Ringing Over Paging
Ringing may be connected to one zone of a Valcom
One-way or Talkback Paging System, or to the
INPUT of a high powered amplifier. The following
components are required:
The following sections contain step-by-step
instructions for wiring the V-9936A and associated
Valcom equipment. Each instruction is preceded by a
line; place a check on the appropriate line as the
instruction is completed. The instructions also
include tests along the way to verify connections have
been made correctly. If these steps are followed
exactly, installation should go smoothly and quickly.
If the results of a test do not correspond with what is
shown, DO NOT PROCEED UNTIL THE
PROBLEM HAS BEEN CORRECTED.
Set individual volume controls at approximately 1/2
volume for testing when installing the control unit
and any one-way amplified speaker assemblies.
Mounting
Remove the metal mounting plate from the rear of the
V-9936A 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. See Figure A.
Open the V-9936A enclosure to access connections
and option switches. Slide the rear of the unit
(contains the board) onto the mounting plate and lock
in place with screw provided. Make connections and
replace cover after all connections are accomplished.
Lock cover in place using the #6 1/2" screw provided.

OPERATION
TECHNICAL ASSISTANCE
When a line rings in, the control circuitry and timer
are activated. While sensing the first incoming ring,
the unit will activate the output relay, disconnect the
page source, and send a one second warble tone and
dry contact closure to the output. The relay will then
drop, and paging will be reconnected. If additional
incoming rings are sensed during the next 4 seconds,
a second tone and closure will be sent. One second
tones and closures will then be sent every 4 seconds
for as long as ringing is sensed on any line. If several
units are connected together using the expansion
leads, all units will send tones if a line rings in on any
unit. Connecting the disable lead (pin 9) to ground
(pin 24) will prevent the unit from being activated.
Connecting a switch between these pins will allow
use of the V-9936A for night ringing. A simplified
schematic of the V-9936A is shown on the next page.
When trouble is reported, verify 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,
several clip leads, a telephone test set available, and
be calling from the job site. Call (540) 427-3900 and
ask for Technical Support, or (540) 427-6000 for
Valcom 24-hour Automated Support or visit our
website at http://www.valcom.com.
The V-9936A is not field repairable. Valcom
equipment contains no user serviceable parts
inside. Valcom, Inc. maintains service facilities in
Roanoke, VA. Should repairs be necessary, attach a
tag to the unit clearly stating your company name,
address, phone number, contact person, and the
nature of the problem. Send the unit to:
