INSTALLATION
Lead Connections
Connect the tip (green) and ring (red) leads of the ringer
to the corresponding leads of the telephone the ringer is
to be used in conjunction with.
•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).
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 signalling 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.
