V-9947A
LINE POWERED LOUD RINGER/HORN
INTRODUCTION
The V-9947A, is a Line Powered Loud
Ringer/Horn which provides amplified electronic
tones for signaling in large or noisy areas. This
instruction contains the specifications and
information necessary to install, operate and
maintain the
V-9947A.
SPECIFICATIONS
Design
The V-9947A is a ringer/horn containing circuitry
to generate incoming call indication via a warble
or single tone when activated by 70-120VAC ring
voltage (Ringer Equivalency Number 2.7A).
To plan a system utilizing the V-9947A, refer to
the Ringer Distance Chart to determine
approximate distances covered. The number
given (ft) is the side to side distance for mounting
the speakers. It is also the distance in front of
the speaker that a good quality signal can be
heard.

INSTALLATION
Lead Connections
Connect the tip (green) and ring (red) leads of the
ringer to the PBX Analog station port.
•To produce a warble tone, the black and white
leads remain unconnected.
•To produce a single tone, connect the black
and white leads to each other (See Figure 3).
The V-9947A is not intended for direct or indirect
connection to the public telephone network or any
telephone line providing dial tone. When used with
a customer premise telephone system such as a
key system or PABX system, these units are
interfaced to the system via a fully protected page
port or system central office port, which is a fully
protected interface device. Also, the host system
must be configured to disallow central office trunk
conferencing in order to prevent indirect
connection to the public network.
Connecting Speaker to Base
The speaker may be attached to the base before
or after the base is mounted.
•Loosen position adjustment knob.
•Insert the ball of the base into the socket of the
speaker.
•Tighten the position adjustment knob.
Mounting
The V-9947A should be mounted 12' to 25' high to
obtain optimum results. This ringer may be used
for either interior or exterior signaling applications.
•Mount the base to a wall using the two holes
provided. Knockout holes are provided for
punch out should additional holes be desired.
•A "C" clamp is provided with the ringer to allow
mounting to a beam. Place the bolt through
the hole in the bottom of the base to secure
the "C" clamp to the beam. (See Figure 1). It
is suggested that the horn be mounted to the
underside of the "I" beam so as to provide the
maximum of positioning adjustments.
•Connection to an electrical backbox is
accomplished by channeling wire through the
ball of the base and making appropriate
connections. The base has holes punched for
a double-gang square box, but by punching
out additional knockout holes, the base can be
mounted to a single-gang or octagon box.
(See Figure 2).
The V-9947A may be rotated or moved up and
down to obtain the desired position by loosening
the position adjustment knob at the bottom of the
unit (See Figures 1 and 2) approximately 1 turn.
Make required adjustment and re-tighten the knob.
TECHNICAL ASSISTANCE
When trouble is reported, verify there are no
broken connections between the telephone and
the ringer. Ascertain volume control is turned
up.
