Which component is NOT required to be present in a fire control center?

The sewage control panel is not a required component in a fire control center because its primary function is related to sanitation and waste management rather than fire safety and emergency response. A fire control center is specifically designed to manage and coordinate fire safety measures during an emergency, focusing on systems such as alarms, communication, and elevators to ensure the safety of occupants and facilitate emergency services.

In contrast, a public address system panel is crucial for communicating important information and instructions to building occupants during a fire. Elevator recall controls are vital for recalling elevators to a specific floor to ensure they are not used during a fire evacuation, thus preventing potential accidents. Status indicators for smoke control systems are important for monitoring and managing smoke movement in the building, which is critical in fire scenarios. Each of these components plays a significant role in enhancing safety and response in emergency situations.
