Abstract

A rapid access door system is provided wherein authorized individuals may pass through the door system and wherein unauthorized individuals are blocked from entering a secured area past the doors and are automatically rerouted to an unsecured area for further processing without blocking the door system and impeding the flow of other individuals entering the door system. The door system uses modular units employing sensing means and a specially configured door which door automatically provides the rerouting of persons in the system. The sensing means determines, among others, the number of persons in the system, whether the door is opened or closed, whether a person has exited the system to particular areas, alerting speakers and signage, with the above information being used in conjunction with the door system to provide a highly efficient and effective rapid access portal system.
