AVT731 B

The system is a specific sound generator with double modulation. The vibrations are generated in the 4046 system, the second scale (4093) was used to configure the inputs controlling the operation of the device. The ability to easily change the frequency allows you to use the system as an alarm device and to deter animals.
A high-efficiency piezoelectric transducer PCA-100 (loudness above 100 dB) was used as the sound source.

The device is recommended as an audio siren, animal repellent (dogs, martins, etc.) and insects (mosquitoes)

Selected parameters:

• sound volume - above 100 dB
