| Zusammenfassung: | The invention relates to a two-bus acousto-optic alarm circuit, which comprises an acoustic alarm circuit and a light alarm circuit. The light alarm circuit comprises a first energy storage control circuit, wherein the first energy storage control circuit is connected with a first non-polar conversion circuit, and the first energy storage control circuit is also connected with an optical circuit.The acoustic alarm circuit comprises a second energy storage control circuit, the second energy storage control circuit is connected with a second non-polar conversion circuit, and the second energy storage control circuit is also connected with an acoustic circuit. The input terminal of the first non-polar conversion circuit is connected in parallel with the input terminal of the second non-polarconversion circuit and is connected with an external control device through two buses to provide working power for the acoustic circuit and the optical circuit. The operation of the optical circuit is controlled by the first |
