Special Service Recall

Kone · Electric Traction Elevators

What does 79 mean?

The KONE LCE W/KDM elevator has been commanded to a special service mode, requiring it to return to a designated floor and open its doors for passenger evacuation. This mode is typically activated for specific operational needs or maintenance.

Common Causes

  • Activation of a dedicated key switch for special service (e.g., Fire Service switch on page 2).
  • Remote command for maintenance or security purposes.
  • Initiation of a specific operational program that requires the elevator to clear passengers.
