Abstract
An elevator access control system monitors a secure area, including an elevator landing, and controls an elevator system with at least one elevator car that is accessible from the elevator landing. Each elevator car of the elevator system has a door at the landing that provides access between the elevator car and the landing. The system includes an access monitoring device that detects the presence of non-authorized individuals within the secure area and produces a breach signal upon detecting one or more non-authorized individuals within or entering the secure area. Upon receiving the breach signal, an access system controller in communication with the access monitoring device initiates a security alert phase.
