Which term describes the electric engine or diesel motor that powers a fire pump, as used in fire protection terminology?

• A. Starter
• B. Motor
• C. Prime mover
• D. Driver

Answer: (D)

The key idea is identifying the component that provides the mechanical drive for a fire pump—the device that powers it. In fire protection terminology, the unit that powers the pump, whether it’s an electric motor or a diesel engine, is called the driver. This term emphasizes the driving force that transmits power to the pump to make it operate. It’s distinct from a starter, which is only the control used to begin operation; from the motor, which is the device that converts electrical energy into motion; and from prime mover, which is a broader term for any energy source that produces mechanical work, but in this context the term driver specifically denotes the power unit driving the pump.
