Physical Locking and Safety Interlocking: Prevents unauthorized personnel from opening the base station hall door, avoiding risks such as falls into the shaft, equipment theft/tampering, etc., complying with EN81/GB 7588 safety standards.

When unlocked, the hall door circuit is cut off, preventing the elevator from starting or stopping at that floor, forming a forced interlock with the door lock monitoring system to ensure operational safety.

Access Control and Misoperation Prevention: Only authorized personnel (property management, maintenance, fire personnel) can unlock the elevator with a special key, preventing passengers from accidentally activating special functions of the base station (such as fire return, independent operation, driver mode).

Lobby call buttons are locked to prevent unauthorized personnel from triggering commands that could cause elevator malfunctions, maintaining vertical traffic order in the building.

Adaptable to Special Operating Conditions and Maintenance

Fire Protection: In case of fire, it coordinates with other systems to ensure the elevator reliably returns to the base station and locks, facilitating evacuation and rescue operations.

Maintenance Operations: It locks the base station hall door to prevent unauthorized personnel from entering the shaft during maintenance, while allowing maintenance personnel to safely enter and exit and control the elevator's operating mode.

Energy Management: Locking the base station during long-term shutdowns or at night reduces unnecessary energy consumption and safety hazards.
