US 7,588,126 B2 · Building evacuation elevator system

Abstract

In the method of the present invention an evacuation mode is presented in an elevator system, which receives destination calls i.e. operates in accordance with so-called destination control. In the method the destination floor calls given on the evacuation floors of the building are changed in the event of an exceptional incident such that the destination floor becomes an exit floor of the building. In the method the elevator car is filled as flail as possible on one floor and the travel time to the exit floor is minimized by directing the elevator car to the escape floor without intermediate stops. The passengers to be evacuated are shown information relating to the evacuation on a display located on the destination call panel and/or inside the car of the evacuation elevator.
