What is the role of the fire pump controller in NFPA 20 systems?

• A. To automatically start and stop the pump under defined conditions and provide status and interlocks
• B. To manually switch the pump only
• C. To regulate the water treatment chemicals
• D. To control only the discharge valve

Answer: (A)

The fire pump controller acts as the automatic command center for the pump. It monitors signals such as system pressure, flow, alarms, and power status, and automatically starts the pump when demand arises and stops it when the pressure or flow is back to the required level. It also provides status indications and interlocks, coordinating with other equipment (like power sources and alarm systems) to ensure safe, reliable operation. It isn’t simply a manual switch, it doesn’t regulate water treatment chemicals, and it doesn’t control discharge valves by itself—the controller’s primary role is automatic start/stop logic plus status and interlocks.
