Abstract

The door protector works similarly to an alarm system terms of its detecting. It can be set either Disarm or Arm. By pressing the Disarm button, we may open and close the door as often as we like and this no effect on the siren. The Arm state will be activated only when the Disarm button is ON. This circuit consists of NAND gate, NOR gate, active and passive components, switches and buzzers and miscellaneous items. The circuit operates at 12V to suit the buzzer and powering CMOS ICs. It not only restricted to the doors, but can be applied to things that can be closed or opened.
