The ETB-188 Electronic Siren Trainer is designed to demonstrate the operation of audio frequency generation using timer ICs, such as the popular IC 555. This trainer simulates a variety of siren effects (ambulance, police, fire) by generating modulated audio tones through frequency control and waveform shaping.

It features:

  • Circuit based on timer ICs in astable and monostable modes

  • Built-in constant regulated (C.R.) power supply

  • Audio output through inbuilt speaker or buzzer

  • Clearly marked test points and control elements for waveform observation

  • Easy-to-understand PCB layout and block diagram

Ideal for basic electronics and audio applications labs, the ETB-188 introduces students to the principles of tone generation, waveform modulation, and the practical use of IC 555 for audio applications.
