Data Sheet

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) repet-
itive 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
seconds 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
seconds on, 0.4 seconds off, 1.6 seconds on, and a
frequency range of 500-1200 Hz. The chime tone shall
be a signal with exponential decay slope of 6.5 seconds,
cycle On/Off timing of 0.3 seconds on, 0.7 seconds off,
and a frequency range of 650-1300 Hz. The steady tone
shall be a square wave with adjustable frequency range
of 650-1300 Hz. The unit shall offer a choice of continu-
ous 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 product weight
shall be 2 lb.
