THREE-TONE SIGNALIZATION DEVICE ZS24, ZS72, ZS110

THE SOUND SIGNALIZATION DEVICE FOR ANNOUNCING THE FAULT ON A CERTAIN DEVICES IN THE RAIL TRACTION VEHICLES; A PART OF THE DEAD-MAN’S CONTROL SYSTEM

•3 types for 3 different supply voltages: 24V DC (ZS24), 72V DC (ZS72), 110V DC (ZS110)
•Massive moulded metal case
•Special loudspeaker with a plastic membrane; water resistant
•Three frequencies (tones) of the sound signalisation: 400Hz, 600Hz, 1200Hz
•4-way terminal block connector; common minus pole and a plus input for each frequency
•Material: AlSiO12
•Electronic circuit is not permanently power supplied; it is supplied only if one of the frequency inputs is activated, what makes the life cycle much longern
• Dimensions (D×W×H): 118×86×65mm

• Simulation of deadman's control system
