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.

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.
