Title: ELEVATOR SYSTEM LANDING DOOR UNLOCKING MECHANISM
Abstract:
A landing floor door access system for an elevator system includes a door lock operably connected to a landing floor door, and a door lock controller operably connected to the door lock. The door lock controller is configured for non-contact communication with an access device such that communication between the access device and the door lock controller initiates a signal from the door lock controller to the door lock to deactivate the door lock. A method of accessing a hoistway of an elevator system, includes approaching a landing floor door of the elevator system, the landing floor door positioned at the hoistway, and initiating communication between an access device and a door lock of the landing floor door via non-contact interaction between the access device and the door lock. The door lock is deactivated via the non-contact interaction between the access device and the door lock.
