FCC Information
This equipment has been tested and found to comply
with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against
harmful interference when the equipment is operated
in a commercial environment. This equipment
generates, uses and can radiate radio frequency
energy and if not installed and used in accordance
with the instruction manual, may cause harmful
interference to radio communications. Operation of
this equipment in a residential area may cause
harmful interference in which case the user will be
required to correct the interference at one’s own
expense.
General Mounting Information
A) Elevated Operating Ambient - If installed in a closed or multi-
unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room ambient.
Therefore, consideration should be given to installing the
equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack
should be such that the amount of air flow required for safe
operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due
to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the
connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent
protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing
this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted
equipment should be maintained.
Particular attention should be given to supply connections other
than direct connections to the branch circuit (e.g. use of power
strips).
F) Equipment only suitable for mounting at heights less than or
equal to 2m (6.56’).
Power Requirements
The V-9972 requires 24 Volt DC power. Power may be
connected using either the barrel connector or two screw
terminals located on the back panel. The recommended
power supply is the VP-624D, or other 24vdc power
supply providing a minimum of 600 mA.

INSTALLATION
Regulatory Information
This equipment is to be installed only in restricted access
areas (dedicated equipment rooms, equipment closets or
the like.
When using this equipment, basic safety precautions
should always be followed to reduce the risk of fire,
electric shock and injury to persons including the
following:
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 interface.
4. Use caution when installing or modifying telephone
lines.
Mounting
Wall: Use the wood screws provided to attach the
brackets to the wall. For surfaces other than wood, use
hardware appropriate for the surface (not included). With
the brackets securely attached to the wall, attach the
V-9972 to the brackets, using the included hardware.
(See Figure 1)
Rack: Two V-9972 units may be joined together and
installed into a 1U rack slot. Using Figure 2 as a guide,
attach the interlock brackets and end mounting brackets
to each of the V-9972 units, then mount the combined
units into an available rack slot.
Connections
Front Panel
The front panel of the V-9972 has the following controls:
• Monitor is a 3.5 mm headset jack for monitoring
audio being sent to the output ports.
• Music volume control adjusts the output level of the
background music to the output port.
• Tone volume control adjusts the output level of the
page pre-announce tone.
• Status LED indicates the operating status of the
V-9972.
• Green indicates powered on and idle
• Amber indicates Page in progress
• Red during the bootup sequence, or to indicate a
fault condition
• Ethernet is an RJ45 ethernet connection with two
status LEDs:
• Green: (Link) Indicates Ethernet connection
when illuminated.
• Yellow: (Activity) Indicator flashes to indicate
network activity
Rear Panel
The rear panel of the V-9972 is located behind a
removable cover and contains the signal connections.
• Power connections are provided with two options.
Either the barrel connector or the two screw terminals
may be used.
• Function Settings is a 6-position DIP switch for
setting feature options. The settings are described
more fully in this document.
• Music In provides two methods for connecting a
background music source. Either the stereo RCA
jacks or the screw terminals may be used. Stereo
signals on the RCA jacks will be combined to mono.
• One Way Page Out is the audio output for speakers
or amplifiers. The background music and paging
audio will output on these two terminals.
• Relay is a normally open relay connection which
closes when a page is active.
• All Call Audio is the audio input connection for
accepting audio from other V-9972 controllers when
the controllers are used in a multiple-zone
arrangement.
• Talkback Page Out is the output connection
providing FXO signaling to establish connection to a
page controller. This connection is typically used with
multi-zone page controllers.
• All Call Control is used in conjunction with the All
Call Audio connection when used with other V-9972
controllers in a multiple-zone arrangement.
• Page Inputs
• FXS provides FXS signaling. This is used with a
single line telephone or PBX loop start trunk port.
Dial tone is provided from this port. This port is
active when SW 6 is ON.
• FXO provides FXO signaling. This is used with
an FXS Station Port and will answer inbound
calls signaled by ring voltage. This port is active
when SW 6 is OFF.
Setup
Basic options to set the Input and Output ports on the
V-9972 must be done using the DIP switch options noted
previously in this document. Other basic settings can
also be accomplished using the DIP switches. Additional
programming can be accomplished using a touch-tone
phone connected to the FXS port or through the web
interface of the V-9972. Separate documentation on
using these features is available on the Valcom web site.

Function Settings DIP Switch
Output Port Selection (SW 1)
Two output connections are available on the V-9972. The Talkback Page Out connection provides FXO
(loop-start trunk) signaling. The One Way Page Out connection provides a standard tip/ring audio output.
The default level of the One Way Page Out is -10dBm, but can be changed in software to +2.2 dBm for
applications that require the higher output level.
Silence Timeout Selection (SW 2 & 3)
Silence Timeout indicates how many seconds the V-9972 will stay active after the audio input has stopped.
This can be used to disconnect a call after the caller has stopped speaking. Three values are available with
the switch settings; additional options are available in software programming.

Input Port selects which of the Page Input RJ11 jacks is active. The ports are labeled FXO and FXS to
indicate the type of signaling provided. The FXS port detects off-hook condition and provides dial tone
to the circuit. The FXS port can be used with a standard phone or loop-start trunk port. The FXO port
is a loop-start trunk port and can be used with a Station Port or FXS on a PBX.
** The V-9972 must be power cycled for any DIP switch changes to take effect. **
