But it keep giving the annoying Buzzer sound on any motion.

Click and hold the doorbell button to see how the buzzer works. When the circuit is closed, the electromagnet is magnetized so it pulls up on the contact arm. This breaks the doorbell circuit, which shuts off the electromagnet. The arm falls down, closing the circuit again and the process repeats.
