Thus we disconnect Pin 11 which generates pulses with 64 Hz frequency. There are a lot of D4990A on Ali. Just raise 11 pin as I wrote but literally by half a millimeter. I have another one approach to your problem from Beeper side. More on this later on. |

Maybe you can follow the beeper signal to know what it triggers and thus understand the conditions and analyze those conditions ? |
