Model TG4C Multiple Tone Generator is capable of generating

four distinct signals:pulsed tone,slow whoop,repeating chime,

and steady tone.Each of these four signals may be applied con-

tinuously or limited to a double burst (single burst only of the

steady tone) for alarm signaling or pre-announcement.Signals

are triggered by an external device that provides a contact

closure.Both tone level and pitch are adjustable.

The TG4C will accept a high-level (max..5V RMS) input from1

a program source,such as a tuner or tape deck.Tone signal

precedence over program input is built-in.When used in con-

junction with a telephone or microphone,the unit provides

pre-announcement signaling for voice messages.

The unit operates from a 12-48V DC source,with either pos-

itive or negative ground.All connections are made at screw

terminals.

INSTALLATION

CAUTION:To reduce the risk of fire or electric shock,do not

expose this unit to rain or excessive moisture.

POWER SUPPLY

The TG4C requires a power source of between 2 to 48V1

DC,either positive or negative ground:

1.Connect the grounding lead from the TG4C chassis to the

positive (+) terminal if a positive grounding system is used.Be

certain that the TG4C chassis does not come into contact

with any other equipment with a negative ground.

2.If a negative-ground system is used,connect the grounding

lead to the negative (-) terminal.

Bogen accessory Model PRS40C Power Supply is available for

operation from 120V AC,60Hz.If used,connect the

BLACK/WHITE lead from the PRS40C to the negative (-) ter-

minal of the TG4C;connect the BLACK lead to the positive

(+) terminal.

TONE LEVEL CONTROL

Tone level can be regulated by using the screwdriver-

adjustable TONE LEVEL control on the front panel.Clockwise

rotation increases the level of the tone signal.

PITCH CONTROL

A recessed,screwdriver-adjustable PITCH control is located

on the side panel and is used to adjust the frequency of the

tone signal.The signal can be varied to suit the individual appli-

cation requirement.

WIRING

The TG4C can be installed in a variety of configurations,

depending upon specific application criteria.

Figure 1illustrates a common method of generating a tone

signal over program (e.q.,tape player or tuner) input.When

the contacts of an external switching device are closed,pro-

gram input is interrupted by a burst of one of the tone signals.

For longer signal duration,connect the CONTINUOUS and

TRIGGER terminals (dashed line).The tone signal will be con-

tinuously generated until the external switch contacts

(ALARM CLOSURE) are reopened.

Note:TBA is used to mute TBA5 amplifier.1
