Bogen TG4C User manual

The Model TG4C Multiple Tone Generator is a compact, reliable unit designed to generate four distinct
signals: pulsed tone; slow whoop; repeating chime; and steady tone.
It is an excellent source for alarm or pre-announce signals in public address or telephone paging systems.
The TG4C will accept a Hi-Z input from a program source, such as a tuner, turntable, cassette player, CD
player, etc., and will maintain precedence over the program material for the duration of the contact clo-
sure.
Multiple Tone
Generator
Model TG4C
• 4 types of tones: steady, pulsed alarm, slow
whoop, and chime
• Tones triggered by external contact closure
(momentary or long duration)

Part No. 54-7779-04R2 Printed in U.S.A. 0211

The multiple tone generator shall be a Bogen Model
TG4C, or equivalent, with a rated output level of one
volt RMS into a 600-ohm load.
The device shall be activated by an external contact
closure. It shall be capable of generating four distinct
signals: (1) pulsed alarm tone, (2) slow whoop, (3)
repetitive chime, and (4) steady tone signal.
The pulsed signal shall be a square wave with cycle on-
off timing of 1.2 seconds on, 0.4 seconds off, 1.6 sec-
onds on, and a frequency range of 650-1300 Hz. The
slow whoop signal shall be a slowly ascending, low to
high swept signal with cycle on-off timing of 1.2 sec-
onds on, 0.4 seconds off, 1.6 seconds on, and a fre-
quency range of 500-1200 Hz. The chime tone shall
be a signal with exponential decay slope of 6.5 sec-
onds, cycle on-off timing of 0.3 seconds on, 0.7 sec-
onds off, and a frequency range of 650-1300 Hz. The
steady tone shall be a square wave with adjustable fre-
quency range of 650-1300 Hz. The all-solid-state unit
shall offer a choice of continuous signal of any of the
four tone-types or double-burst signal of any tone
type except the steady tone.
The tone generator shall accommodate input from a
high-level program source. Built-in precedence shall
allow the tone signal to override program material.
When used with a public address amplifier, the unit
shall be capable of pre-announce signalling of a voice
announcement over the program source.
Both the output level and pitch control shall be
adjustable. The unit shall operate from 12-48V DC,
positive or negative ground. Construction shall be
steel, finished in silver gray. The overall dimensions
shall be 6-3/4" W x 5-3/4" H x 2" D. The shipping
weight shall be 3 lb.
