Wiring Requirements
Due to the small amount of signal and power
required, wiring may be accomplished through station
or other suitable wire. When using "D" type station
wire, limit the wire run to 500 feet. Two Loud
Warble Ringers may be connected to the same
cabling if the total run length is less than 250 feet.
When a remote power unit is used, signal input leads
should be limited to 5000 feet and a maximum of 6
ringers.
INSTALLATION
Connections
Connect station or other suitable wire to the leads as
follows:
White
-24VDC
Black
Ground
Brown
Sig. Common
Red
105VAC input
Green
20VAC input
NOTE: Use either the 105VAC or 20VAC input,
not both.
When used in conjunction with a buzzer, connect the
buzzer leads to the brown and green leads. When
used with a ringer, connect the ringer leads to the
brown and red leads.
Attaching Speaker to Base
NOTE: For ease of installation, the base can be
attached to the speaker before or after the base is
attached.
•
Loosen position adjustment knob.
•
Insert the ball of the base into the socket of the
speaker.
•
Tighten the position adjustment knob.
Mounting
The V-9925A should be mounted 16 to 40 feet above
the floor to allow for best sound distribution. The
unit can be mounted to a wall, a beam or an electrical
box.
•
Mount the base to a wall using the two holes
provided. Knockout holes are provided for
punchout 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).
•
Connection to an electrical backbox is
accomplished by channeling wire through the
ball of the base and making appropriate
connections (see Figure 2). 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.
The V-9925A may be rotated or moved up and down
to obtain the desired position by loosening the knob
at the bottom of the unit approximately 1 turn (see
Figures 1 and 2). Make required adjustment and
re-tighten knob.
TECHNICAL ASSISTANCE
When trouble is reported, verify -24VDC power is
being applied to the unit and that the white wire has
-24VDC battery and the black wire is at ground
potential. Using a VOM, verify that 105VAC or
20VAC is being applied to the signal leads. Check
the volume adjustment on the control unit to make
certain it is set at the proper level.
Assistance in troubleshooting is available from the
factory. When calling, you should have a VOM and a
telephone test set available and be calling from the
job site. Call (540) 563-2000 for Technical Support
