V-9925A

LOUD WARBLE RINGER WITH VOLUME CONTROL

5 WATT -24VDC

INTRODUCTION

These instructions contain the specifications and

guidelines necessary to install, operate and maintain

the V-9925A, 5-Watt Loud Warble Ringer with

Volume Control.

SPECIFICATIONS

The V-9925A Loud Warble Ringer is a

self-contained 5-Watt electronic ringer which can be

used for either interior or exterior signaling

applications. The unit is designed to allow a loud

warble to be broadcast as long as input signal is

present. The input signal should be interrupted or

controlled by the ringing interval.

Application

 Loud speaker tone signaling for key systems,

intercoms, PABXs

 Outside signaling for incoming calls into a key

system

 Signaling in a noisy environment

Features

 5 Watt amplifier

 Volume control

 High efficiency horn

 Tone generation circuitry

Coverage

Refer to the following table for speaker coverage.

The first number given is the side to side distance for

mounting the speakers. It is also the distance in front

of the speaker that you can expect to hear a good

quality signal. The second number is the area being

covered in square feet.

Location Distance Area

Quiet 220 ft. 48,400 sq. ft.

Moderate 160 ft. 25,600 sq. ft.

Noisy 80 ft. 6,400 sq. ft.

Very Noisy 40 ft. 1,600 sq. ft.

Environmental

 Temperature: -20 to +55°C

 Humidity: 0 to 95% (non-precipitating)

Dimensions/Weight

 6.50"H x 8.20"W x 10.40"D,

plus mounting base

(16.51cm H x 20.83cm W x 26.42cm D)

 3.6 lbs. (1.63kg)

Signal/Power Requirements

 Power Supply: -24VDC, 500mA ("B" Battery)

(10 Valcom power units)

 Signal Source: 105VAC or 20VAC

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 and press 1 for
