It goes on when a thin wire which is as thin as a hair is broken.The 555 IC acts as an astable multivibrator. It will produce a tone of 1kHz frequency which gives a noise that scares away the stealer. Thin copper wire such as SWG 36 or higher can be used to set off the alarm. Single strands of copper from a power cable can even be used. This schematic operates on a wide range of voltage between 5V to 15V. The circuit diagram is as follows :
