What must fire control centers have to manage elevators?

The correct choice emphasizes the essential features that must be present in fire control centers for effective elevator management during emergencies. Having status indicators and controls for elevators is crucial because it allows operators to monitor the operational status of each elevator and communicate vital information to first responders.

These indicators provide real-time updates about whether elevators are in use, malfunctioning, or available for fire service access, which is critical during a high-rise evacuation or firefighting operation. Control capabilities enable the operator to safely manage elevator operations, such as recalling them to a designated floor away from fire and smoke or restricting access to prevent occupants from using elevators that could expose them to dangers.

While the other options may pertain to elevator operations in general, they do not specifically address the core requirement for a fire control center to effectively manage elevators during an emergency scenario. Specifically, control panels for firefighting departments and remote-controlled elevators are tools that may assist in overall operations but do not directly fulfill the need for real-time monitoring and operational control highlighted in the correct answer. Backup elevators, while practical, do not address the immediate management need required by a fire control center in an emergency context.
