Before providing open signal, automatic door lock must be in the state. Access control systems ranging from simple key switch, locks, magnetic locks. (Attendance statistical system). To complex weight recognition systems, fingerprint recognition systems. But no matter how complex systems are ultimately provide a signal to open the automatic door contacts. Shielded signal circuits unrelated to avoid interference due to signal and error occurrence is very important to open the door.
