Abstract: An illustrative example embodiment of a device that facilitates installing at least one elevator door component, includes a detector that is configured to detect at least one reference feature in a vicinity of a desired position of the elevator door component. A processor is configured to use information from the detector to determine the desired position of the elevator door component relative to the at least one detected feature. An indicator is configured to provide at least one indication corresponding to the desired position of the elevator door component.

Abstract: A method of avoiding unnecessary safety brake actuation in an elevator system. The method includes determining whether a true overspeed or overacceleration condition of an elevator car is present. The method also includes activating the electronic safety actuator if a true overspeed or overacceleration condition of the elevator car.
