Abstract: An elevator system having a hoistway having a bottom landing with landing doors. An elevator car is in the hoistway, and a safety chain is coupled to the car and is in an open-state to stop the car and otherwise in an intact-state. A first sensor wirelessly transmits a first signal when the car is at the bottom landing, and a second sensor transmits a second signal when the doors are open. The system includes a control circuit including a first control element that receives the first signal indicating the car is at the bottom landing and a second control element that receives the second signal indicating the landing doors are open, and the control circuit changes state upon receipt of the signals, and the safety chain transitions to the open-state from the intact state when the control circuit changes state.

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.
