What elevator mode is used for elevator maintenance?

• A. Up peak mode
• B. Down peak mode
• C. Independent service mode
• D. Inspect mode

Answer: (D)

Inspect mode is the setting technicians use for maintenance and testing. In this mode the elevator isn’t dispatched to serve normal passenger calls, which keeps the system safe while work is done. A service key or panel control lets the technician manually move the car to specific floors, open and close doors, and test safety devices and interlocks without interference from regular operation. This dedicated environment is what makes maintenance checks reliable and safe. The other modes are traffic-management or service-oriented but not specifically designed for inspection and thorough testing. Up peak and down peak adjust how the elevator handles frequent passenger calls during busy times, which isn’t about maintenance. Independent service mode allows controlled movement for service reasons but isn’t the standard mode for performing inspection and safety checks.
