Which statement best describes Phase two mode in relation to emergency operation?

• A. It enables emergency personnel to manually operate an elevator that is in Phase one mode
• B. It automatically recalls the elevator to the lobby
• C. It disables all safety interlocks during emergencies
• D. It puts the elevator into normal operation

Answer: (A)

Phase two mode is the firefighter’s service mode. After Phase I recall brings elevators to a designated floor and disables normal automatic operation, Phase II allows emergency personnel to manually operate the elevator car using a special control, enabling them to move the car where it’s needed during the incident. This is why describing Phase II as enabling manual operation of an elevator that has already been recalled to the lobby best captures its purpose. The other ideas refer to Phase I recall, to bypassing safety features, or to returning to normal operation, which are not what Phase II does.
