Description of operation The unit receives the 315 MHz signal and then a low pass amplifier will extract the code on the 315 MHz signal. The decoder IC compares the code with the setting code of dip-switch then sends a interrupt signal to the micro-processor if they had the same code. Once the micro-processor received the interrupt signal will output a analog melody to make the bell sound.
