Bogen TG4C - User Manual

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. 1.5V RMS) input from
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 12 to 48V
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 1 illustrates 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 TBA15 amplifier.
