The elevator landing door lock device 50-11-left is a safety interlock used in elevator systems with automatic telescopic and side-opening landing doors. It is mainly used with Fermator door systems, which are common in passenger and service lifts.
The device performs two functions. It locks the landing door when the door is closed and provides a safety signal to the lift control system. The lift will only operate when the lock confirms that the door is closed and secured.
This model is designed for left-hand door openings. Using the correct left-hand version is required for proper fitting and safe operation. The lock is used by lift technicians during installation, service, and replacement work.
