The elevator LOP set up down is a step-type landing operating panel (LOP) designed for elevator landings. It combines both UP and DOWN call buttons in a single unit, allowing passengers to request the lift in either direction from the same floor.
As part of the elevator landing operating panel, the duplex down call button is linked to the group control elevator system to support down call registration within a shared lift environment. This setup supports down call operation within group-controlled lift systems.
