Multiple Tone Generator Model TG4C Description 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. Features 4 types of tones: steady, pulsed alarm, slow Built-in precedence over interconnected whoop, and chime program source Tones triggered by external contact closure Accessory AC adapter (Model PRS40C) (momentary or long duration) available for operation from a 120V AC, 60 Hz source Choice of continuous or two-burst tone (except for steady tone) 600-ohm output Tone generation reset available Line-matching transformer (Model WMT1A) available for standard 600-ohm telephone Adjustable tone level and pitch line connections Operates on 12 - 48V DC, positive or negative Screw terminal connections ground Specifications subject to change without notice. 2002 Bogen Communications, Inc. 54-7779-04C 1202Rated Output: 1 volt RMS Technical Load Impedance: 600 ohms or higher Specifications Signal Specifications Pulsed: Square wave with cycle On/Off timing of 1.2 seconds on, 0.4 seconds off, 1.6 seconds on, and frequency range of 650-1300 Hz Slow Whoop: 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 frequency range of 500-1200 Hz Chime: Signal with exponential decay slope of 6.5 seconds, cycle On/Off timing of 0.3 seconds on, 0.7 seconds off, and frequency range of 650-1300 Hz Steady: Square wave with adjustable frequency range of 650-1300 Hz Modes of Operation: Choice of continuous signal (until interrupted) of any of four types or two bursts of pulsed, slow whoop, or chime tone Controls: Tone Level, Pitch Termination: Screw terminals Semiconductors: 7 ICs, 4 transistors, 21 diodes Power Requirements: 12-48V DC (30 mA 24V DC), positive or negative ground Dimensions: 6-3/4 W x 5-3/4 H x 2 D Product Weight: 2 lb. Finish: Silver gray Associated Equipment: Model PRS40C 120V AC, 60 Hz Power Supply Model WMT1A Line-Matching Transformer Architect The multiple tone generator shall be a Bogen Model The tone generator shall accommodate input from a TG4C, or equivalent, with a rated output level of one volt high-level program source. Built-in precedence shall and Engineer RMS into a 600-ohm load. allow the tone signal to override program material. Specifications When used with a public address amplifier, the unit The device shall be activated by an external contact shall be capable of pre-announce signalling of a voice closure. It shall be capable of generating four distinct announcement over the program source. signals: (1) pulsed alarm tone, (2) slow whoop, (3) repet- itive chime, and (4) steady tone signal. Both the output level and pitch control shall be adjustable. The unit shall operate from 12-48V DC, The pulsed signal shall be a square wave with cycle positive or negative ground. Construction shall be On/Off timing of 1.2 seconds on, 0.4 seconds off, 1.6 steel, finished in silver gray. The overall dimensions seconds on, and a frequency range of 650-1300 Hz. shall be 6-3/4 W x 5-3/4 H x 2 D. The product weight The slow whoop signal shall be a slowly ascending, low shall be 2 lb. 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. 50 Spring Street, Ramsey, NJ 07446 USA Tel.: 201-934-8500 Fax: 201-934-9832 www.bogen.com
