<p>An elevator access control system monitors a secure area (12) including an elevator landing (6) and controls an elevator system with at least one elevator car (4) that is accessible from the elevator landing (6). Each elevator car (4) of the elevator system has a door (26) at the landing (6) that provides access between the elevator car (4) and the landing (6). The system includes an access monitoring device (14) that detects the presence of non-authorized individuals within the secure area (12) and produces a breach signal upon detecting one or more non-authorized individuals within or entering the secure area (12). Upon receiving the breach signal, an access system controller (22) in communication with the access monitoring device (14) initiates a security alert phase. For each elevator car(4) with an open door status during the security alert phase, the system prevents user control of the elevator car (4) and holds the respective doors (26) open for a remainder of the security alert phase.</p> |
