Abstract
A system for controlling access to a restricted area in a building includes a sliding door system and a controller. The sliding door system has a door frame and a sliding door which can be moved in the door frame between a closed position and an open position. The door frame has a passage region and a wall shell region which at least partially accommodates the sliding door in the open position. The sliding door has an end face which faces the passage region in the open position. The controller has a processor unit and a sensor unit. The controller is designed to generate an alarm signal if a height of an object in the passage region, as determined by the sensor unit, deviates from a height range stored for the object.
