Data Sheet

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,

CD player, etc., and will maintain precedence over the program material for the duration of the

contact closure.
