Which elevator mode allows emergency personnel to manually operate an elevator that is currently in Phase one mode?

• A. Phase two mode
• B. Phase one mode
• C. Normal operation mode
• D. Standby mode

Answer: (A)

In elevator fire safety, Phase I recall brings the car back to a safe floor and suspends normal operation to keep the system from moving during a fire. To give emergency personnel the ability to control the elevator despite that recall, a separate mode called Phase II firefighter operation is provided. Phase II is specifically designed so firefighters can manually operate the elevator—select floors, move the car, and open doors using designated switches or keys. So when an elevator is in Phase I recall and responders need to operate it manually, Phase II mode is the mode that makes this possible.
