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.
