The elevator landing door lock device 50-11-right is a safety interlock used in lift systems. It is made for right-hand opening landing doors. This lock is commonly used with automatic telescopic and side-opening doors supplied by Fermator.
The device locks the landing door when it is closed and sends a safety signal to the lift controller. The lift will run only when the door is fully closed and the lock contact is made. This helps reduce the risk of door opening when the car is not at the floor.
It works as part of the lift safety circuit. It does not drive the door and does not work as a motor part. Its role is limited to locking and safety checking, as required by lift safety rules used in the UAE.
