Two transistors form a clock generator with adjustable frequency, while another two transistors are used to generate the audio signal. The output amplification is provided by a single transistor.
The siren operates from a DC supply voltage in the range of 9 to 12 V. A standard dynamic loudspeaker with an impedance of 4 to 8 OM can be used as the sound emitter.
