What is the typical starting method for a diesel engine fire pump in NFPA 20?

• A. Manual start only
• B. Automatic starting via the pump controller or manual start
• C. Electric start only
• D. Starter is not required

Answer: (B)

Diesel engine-driven fire pumps in NFPA 20 are designed to start both automatically and manually. The pump controller can automatically start the engine when there’s a demand for pressure or a loss of power, ensuring the pump comes online without human intervention during a fire. At the same time, there is a manual start option so the pump can be started for testing, maintenance, or if automatic starting isn’t available. This dual capability is why automatic starting via the pump controller or manual start is the typical method. The other options don’t provide both automatic capability and manual control, and claiming no starter is required ignores the diesel engine’s need for a starting mechanism.
