Elevator access systems having an access control module operably connected to an elevator system and an access device located within the access control module and removable therefrom, wherein when the access device is within the access control module a normal mode of operation of the elevator system is activated and when the access device is removed from the access control module, the elevator system enters a safety mode of operation.

A method of controlling building systems including detecting a status parameter of a door of a building; displaying the status parameter of the door on a device; detecting a status parameter of a door lock, the door lock being operbly connected to the door; and displaying the status parameter of the door and the status parameter of the door lock on a device.

A hoistway landing door locking system includes an elevator shaft and an elevator car disposed within the elevator shaft and moveable therein between a plurality of access openings located at a plurality of levels of the elevator shaft. Also included is a mechanical locking assembly disposed proximate at least one of the access openings, the mechanical locking assembly operable to switch the access opening between a locked condition and an unlocked condition. Further included is an electromagnetic locking assembly operable between an energized condition and an unenergized condition, wherein the energized condition is required to switch the mechanical locking assembly from the locked condition to the unlocked condition.

An arrangement for controlling a lock of an upmost landing door of an elevator, an elevator and a method. The arrangement comprises an actuator arranged to be activated in consequence of activation of a service limit device of the elevator, the actuator being connected to the lock of the upmost landing door, and said activation of the actuator arranged to open said lock.

An access control arrangement of a conveyor system, a mobile device, a conveyor system, and a method for controlling access in a conveyor system are disclosed. The conveyor system includes a manual key-operated access mechanism operable via a key-hole by a key. The access control arrangement includes a communication device for communicating with a mobile device, and a blocking member configured to cover the keyhole in a first position for blocking external access, and to expose the keyhole in a second position, the blocking member being movable between the first and the second positions. The access control arrangement is configured to lock the blocking member in the first position, and release it from the first position in response to receiving a release signal by the communication device.

An illustrative example embodiment of an elevator door lock includes a latch that is moveable between a locking position and a released position. The latch includes a locking surface configured to engage a stop when the latch is in the locking position. A magnet is situated to magnetically attract a portion of the latch to selectively move the latch from the locking position into the released position.

A locking system that locks and unlocks a door of an elevator car travelling along a track having stopping points and associated stopping point zones includes a lock mechanism having a locking position wherein the door is immobilized in a closed position and an unlocking position wherein the door can be opened, an actuator for bringing the lock mechanism into the locking and unlocking positions, and a control device activating the actuator to bring the lock mechanism into the unlocking position when the car is located in the region of a stopping point zone. A position detecting unit continuously detects the position of the car relative to the track and communicates the position to the control device that continuously detects whether the car is located in the region of a stopping point zone by comparing the communicated car position to stored position limit values of the stopping point zones.

An elevator system includes a hoistway; and an elevator car (12) disposed in and drivable along the hoistway, the elevator car including: an elevator car door (38); an elevator door motor (40) operably connected to the elevator car door to selectably open and close the elevator car door; and a door motor brake (52) disposed at the elevator car door and selectably engageable with the elevator door motor to prevent operation of the elevator door motor thus preventing undesired opening and/or closure of the elevator car door.

Disclosed is an elevator control system configured to control movement of an elevator car (12) along an elevator hoistway (26) between a starting position and a destination position (L2), the control system comprising a car holding position monitoring unit configured to monitor whether the elevator car (12) has moved upwards or downwards in the hoistway (26) during a holding period (68) where the car (12) was intended to remain stationary at the destination position (L2). The car holding position monitoring unit is configured to: Receive a first trigger signal (62) from a first car position reference system (40); upon receipt of the first trigger signal, receive signals from a further car position reference system to detect a first indicator (66) indicative of a travel distance (X2) between the position of the elevator car (12) in the hoistway (26) when receiving the first trigger signal (62) and the position of the elevator car (12) in the hoistway (26) when stopping at the destination position (L2); upon receipt of a further service call for the elevator car (12), receive further signals from the further car position reference system and receive a second trigger signal (70A) from the first car position reference system (40) to detect a second indicator (74A) indicative of a travel distance between the position of the elevator car (12) in the hoistway (26) at the end of the holding period (68) and the position of the elevator car (12) in the hoistway (26) when the elevator car (12) receives the second trigger signal (72A) from the first car position reference system (40); and detect whether the elevator car (12) has moved during the holding period (68) based on a comparison of the first indicator (66) and the second indicator (74A).

An elevator alignment system providing alignment between respective sills of an elevator car and an entrance landing to/from which the cab is scheduled, via alignment members disposed with the sills.
