ABSTRACT:
A method of assigning a user to an elevator system with several elevators wherein a user issues a destination call, at least one elevator is determined to serve the destination call and is announced to the user by an acoustic signal that identifies the elevator. All of the signals that designate the different elevators are exclusively formed by one single single-frequency signal tone, the various signals that identify the individual elevators being distinguishable to the user by a predefined signal duration and/or at least one predefined signal interruption. The invention further relates to an elevator system that is equipped for this method.
