Abstract
An arrangement for bringing an elevator car to safety at a faster speed. The arrangement comprises high-speed and slow-speed zones. When the elevator car is located at a slow-speed zone, a standard rescue speed is used. When the elevator is located at a high-speed zone, a faster operating speed is used. The speed zones are indicated inside the elevator shaft in a machine-readable manner.
