Abstract

A door security system for controlling access through a door of a secured area by controlling a lock status of an associated locking unit of the door. The system includes an operator that operates the locking unit of the door, a key pad, a magnetic card reader, and a contact activatable data port. A data processor is responsive to the magnetic card reader, the data port, and the keypad for controlling the operator. Each of the keypad, the magnetic card reader, and the contact activatable data port can manipulate the lock status of the locking unit of the door. The data processor further comprises link means for requiring multiple entries for implementing the lock status of the door.
