According to an aspect, a method includes monitoring a plurality of vibration data by a vibration monitoring beacon and determining that the vibration monitoring beacon has been installed at a service location based on detecting an installation characteristic signature in the vibration data. The vibration monitoring beacon can transition into a learning mode based on determining that the vibration monitoring beacon has been installed at the service location. The method can also include monitoring for a learning mode termination event and transitioning the vibration monitoring beacon from the learning mode to a normal operation mode based on detecting the learning mode termination event.

A door system for an elevator car includes: at least one door leaf for closing a partial region of a car opening of the elevator car; and a mounting device that mounts the door leaf on the car slidably in a direction of a sliding axis between an open position, in which the door leaf releases the partial region, and a closed position, in which the door leaf closes the partial region, and additionally mounts rotatably about a rotation axis so that the door leaf, when slid into the closed position and/or into an intermediate position between the open position and the closed position, can be rotated into an emergency open position in which the car opening is released to an extent that the can be evacuated via the car opening.

An elevator car (6) configured for moving in a hoistway (4) between a plurality of landings (8a-8d). The elevator car includes a floor (6a) provided at a bottom of the elevator car and at least one floor hatch assembly (22) formed in the floor. The at least one floor hatch assembly (22) is movable between a closed configuration and an open configuration. When arranged in the open configuration, the at least one floor hatch assembly (22) provides an opening (60) in the floor (6a) of the elevator car (6) that allows a person (20) to access a space (24) in the hoistway (4) below the elevator car (6) from inside the elevator car (6). When the floor hatch assembly (22) is in the open configuration, the area of the opening (60) provided in the floor (6a) of the elevator car (6) covers an area of at least 0.35 m2.
