Tak bym to określił, zgodnie z poniższą definicją:
"RDF CN recall drive feature
RDF CN is used by maintenance to move the elevator car to the nearest floor to let the passengers out. RDF CN is part of a built-in supervision system that protects the passengers from danger and discomfort.
With RDF CN, passengers can exit the elevator safely if a system failure occurs. Separate up and down push buttons are used to move the elevator. The buttons are located in the control panel. There is also an additional run button to ensure that the recall drive is not used accidentally. To move the elevator, both the run button and the direction button (up or down) must be pushed.
Due to local regulations, SED service drive overrides RDF CN in simultaneous use."
