Independent service is a special service mode found on most elevators. It is activated by a key switch either inside the elevator itself or on a centralized control panel in the lobby.

How it works

When an elevator is placed on independent service, it will no longer respond to hall calls. In a bank of elevators, the traffic is rerouted to the other elevators, while in a single elevator, the hall buttons are disabled.

The elevator will remain parked on a floor with its doors open until a floor is selected and the door close button is held until the elevator starts to travel. Some elevators have you hold the button of the button of the desired floor in until the elevator starts moving.

Independent service is useful when transporting large goods or moving groups of people between certain floors.

Trivia

  • In ThyssenKrupp elevator, the key type is L203 to activate the mode in these elevators.
