V-9945A

SINGLE TONE/INTERRUPTED

WARBLE TONE LOUD HORN

INTRODUCTION

The V- -9945A is a horn with built in tone generator

and amplifier used for loud signaling applications.

These instructions provide identification, connection,

installation, operation and maintenance information

for the V-9945A, Single Tone/Interrupted Warble

Tone Horn Ringer.

SPECIFICATIONS

Purpose

The V-9945A provides amplified electronic tones for

signaling in large or noisy areas or outside.

Applications

• Night ringing

• C. O. audible ringing

• Time clocks

• Special purpose signaling

Features

• Self-contained tone generator, amplifier, volume

control and horn speaker

• Single tone or warble tone outputs

• Power supply included

• Activated by dry contact closure

• Single tone will override warble tone

• Warble tone interrupted 1 second on, 5 seconds

off

• Single tone continuous for duration of closure

• Weatherproof

• Units may be multipled for simultaneous access

Capacity

The V-9945A has provisions for two inputs, either or

both of which can be used in an application. If both

inputs are activated simultaneously, the single tone

will override the warble tone.

The V-9945A is a stand alone ringer horn activated by

a relay. If more than one ringer horn is required,

contact Valcom Technical Support at (540) 563-2000

for design assistance.

Dimensions/Weight

• 6.50"H x 8.20"W x 10.40"D, plus mounting

bracket

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

• 4.3 lbs. (1.95 kg)

Power Requirements

-21.5 to -26.0VDC "B" battery, 250mA nominal.

Environment

• Temperature: -20 to +55 degrees C

• Humidity: 0 to 95% non-precipitating

DESIGN

Access Requirements

The V-9945A requires a dry contact closure for

activation of each tone (If both tones will be used,

two closures are required). The closures may be in

the form of night ringing relay contacts, time clock

contacts, a standard normally open switch or

equivalent.

Equipment Requirements

A system using the V-9945A will consist of the

following:

• Access equipment (See Design Section)

• -24VDC power supply (Included with horn)

INSTALLATION

General

These instructions cover only the installation

procedure for the Valcom V-9945A. Please consult

practices for other equipment if any other equipment

is being used.

Precautions

All precautions have been taken at the factory to

insure that the equipment functions properly. To

insure proper operation and to prevent equipment

damage, please observe the following:

• Unplug the power supply before making any

connections to the unit.

• Do not apply power to the unit until all

connections have been double-checked.

Attaching Speaker to Base

NOTE: For ease of installation, the base can be

attached to the speaker 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-9945A should be mounted 12 feet to 25 feet

high in the area requiring signaling. 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

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 2).

• Connection to an electrical backbox is

accomplished by channeling wire through

the ball of the base (See Figure 3) 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.

The V-9945A may be rotated or moved up and down

to obtain the desired position by loosening the knob

(See Figures 2 and 3) at the bottom of the unit

approximately 1 turn. Make required adjustment and

re-tighten knob.

Lead Designations

Black Ground (+)

White -24VDC

Red Warble tone access

Green Common

Brown Single tone access

Connections

Connections should be accomplished using twisted

pair telephone wire. The power supply should be

located within 500 feet of the horn.

• Connect negative (-)(-24VDC) lead of the

power supply to the white lead; connect

positive (+)(Gnd) lead of the power supply to

the black lead.

• For warble tone access, connect contact

closure between red and green.

• For single tone access, connect contact

closure between brown and green.

Connections for both single tone and warble tones

may be made to the same speaker.

OPERATION

General

The V-9945A is a horn speaker containing circuitry to

generate single and dual electronic tones, as well as a

5 Watt amplifier and volume control. It also contains

a timer to interrupt the warble tone signal (1 second

on, 5 seconds off). When the red and green leads are

connected together (Through a contact closure), the

warble tone and interrupter circuits are activated.

When the brown and green leads are connected, the

circuitry for the single tone is activated. If both

closures are applied, the single tone will be sent.

TECHNICAL ASSISTANCE

When trouble is reported, verify that power is being

supplied to the unit and there are no broken

connections. Check voltages for proper polarity on

the crossconnect block.

A lineman's test set, several clip leads and a VOM

may be necessary to effectively troubleshoot the unit.

Table 1 identifies symptoms of some possible

problems with solutions. If your problem is listed,

perform the actions indicated.

If the trouble has not been located, continue to

troubleshoot by substituting a spare unit for the

suspected unit.

Assistance in troubleshooting is available from the

factory. When calling, you should have a VOM and a

test set available and be calling from the job site. Call

(540) 563-2000 and ask for Technical Support or call

(540) 767- -1555 for Valcom 24 hour Faxback System or
