Cop / Lop

The Landing Operating Panel (LOP) is the control panel located outside the elevator car or lift on each floor or landing. It allows passengers waiting for the elevator to call the lift car to their floor and specify their desired destination floor.

Function:

The LOP typically consists of floor buttons corresponding to each floor in the building. When a passenger on a particular floor wants to use the elevator, they press the button for their destination floor on the LOP. This action sends a signal to the elevator control system, which then dispatches the appropriate elevator car to the passenger's floor.
In summary, both the COP and LOP are essential components of elevator or lift systems. The COP allows passengers inside the elevator to control its operation, while the LOP enables passengers on each floor to call and specify their desired destination, ensuring efficient and safe transportation between different floors of a building.
