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
