V-9924C

COMMON AUDIBLE RINGING UNIT

GENERAL

The Common Audible Ringing Unit provides an

audible signal over the paging system when

there is an incoming call. It is used between a

telephone system and the public address

system.

SPECIFICATIONS

Activation

• 1A2 Bell/Buzzer ICM

• PABX Station Port

• Contact Closure

Features

• Activates via ringing voltage, buzzer voltage

or contact closure

• Capable of switching signal to three zones

simultaneously

• Uses standard 1A2 key system voltages

• Each zone is equipped with a 5 Watt

amplifier and volume control

• Screw terminal connection

• Compact size, can be mounted on wall or in

cabinet

• Automatically switches paging speakers

from paging system to audible signal of the

V-9924C during the ring interval of the

incoming call

• Variable pitch control

• Two auxiliary contact closures

Other Materials Required

• -24VDC power supply

• Cat 3 or 5 twisted pair telephone cable

• Mounting screws and hardware

Dimensions/Weight

• 8.20" H x 4.55" W x 2.30" D

(20.83cm H x 11.56cm W x 5.84cm D)

• 1.3 lbs. (0.59kg)

Power Requirements

The V-9924C requires a -24VDC "B" battery

and draws 50mA idle and 300mA maximum

operating.

Signal Requirements

The V-9924C requires interrupted ringing or

buzzer voltage or dry contact closure to operate.

The output of the V-9924C will follow the

interruptions of the input. The ringing voltage

should be approximately 90VAC and the current

requirement would be 8mA. The buzzer voltage

should be approximately 18VAC and the current

requirement would be 10mA. The V-9924C

pulls approximately 3mA through a dry contact

closure for activation. Ringing and buzzer

voltages cannot be applied simultaneously. Use

only one method of activation.

INSTALLATION

Precautions

Failure to observe the following precautions

could result in damage to the V-9924C and

other equipment.

a. Unplug the power supply when connecting

the power leads and signal leads to the unit.

These leads are brought in on adjacent

terminals. Accidental bridging of these two

terminals could damage the equipment.

b. Use pared crossconnect wire for all voice

connections and voltages.

c. Set all volume controls to their minimum

(counter clockwise) level.

Mounting

Remove the metal mounting plate from the rear

of the V-9924C enclosure. Using two #6 ¾"

wood screws, mount the plate in a vacant space

on the backboard with the telephone system

common equipment. Both mounting holes

must be utilized to insure secure mounting

of the unit (see Figure 1A).

Open the V-9924C enclosure to access

connections and option switches. Slide the rear

of the unit (contains the board) onto the

mounting plate and lock in place with screw

provided. Make connections.

Signaling Connections

The V-9924C can be activated via ringing

voltage, buzzer voltage or a dry contact closure.

When used with buzzer voltage, apply one side

of the pair to SIG COMMON (pin 11 or 26) and

the other side of the pair to 18VAC SIG (pin 12

or 27). For ringing voltage connections, put one

side of the pair on SIGCOMMON (pin 11 or 26)

and the other side of the pair to 90VAC SIG (pin

13 or 28).

The V-9924C can also be activated by

connecting one side of a dry contact closure to

pin 7 and the other side of the dry closure to pin

22.

Speaker Connections

The V-9924C Common Audible Ringing Unit is

capable of switching up to three zones of

speakers to the audible signal generated by the

unit. The device is intended to be placed in

series with the speakers. Zone 1 IN (pins 16

and 17) are connected to the speaker/zone

output leads of the page control. Zone 1 OUT

(pins 1 and 2) are connected to the speakers.

Zones 2 and 3 hook up in a similar fashion.

Refer to Figure 2B for pin numbers.

Power Connections

Connect -24VDC from the power supply to pin

15 or 30 on the crossconnect block and ground

to pin 14 or 29.

Contact Closure

Two form C auxiliary contact closures are

provided on the V-9924C. These contacts

follow the input cadence and may be used for

special applications. The contact ratings are 1

Amp at 24VDC.

Set Up

After all connections are complete and double

checked, apply voltage to the unit. Place a call

to the telephone system and while ringing or

buzzer is being applied to the unit or when the

dry contact closure closes, adjust the volume of

each zone by turning the volume control

clockwise for each zone. Replace cover when

all connections and adjustments are complete

and lock in place using the #6 ½" screws

provided.

OPERATION

Figure 3 shows a V-9924C simplified schematic.

When the V-9924C is idle, 1T IN is shorted to 1T

OUT, 1R IN is shorted to 1R OUT, 2T IN is

shorted to 2T OUT, 2R IN is shorted to 2R OUT,

3T IN is shorted to 3T OUT and 3R IN is shorted

to 3R OUT.

A signal appearing at the T IN, R IN terminals

will also appear at the T OUT, R OUT terminals

for each zone.

Signaling

When ringing or buzzer voltage appears at the

signaling input leads of the V-9924C or UNA

closure pins are connected, relays are

energized and the 1T OUT, 1R OUT, 2T OUT,

2R OUT, 3T OUT, and 3R OUT leads are

switched to the outputs of three 5 Watt

amplifiers (one for each zone). At the same

time, the electronic warble tone is connected to

the input of each of the amplifiers and the warble

signal (which follows the interrupted ringing

pattern) is broadcast to all of the speakers.

Each zone has its own volume control so the

volume can be set to a comfortable level.

Pitch Control

Dipswitches have been provided to vary the

pitch of the warble ring tone should a different

pitch be desired. Generally, this control does

not require adjustment (see Figure 2B). If

adjustment is necessary, see chart to select

desired pitch (see Figure 2A).
