What is the function of a fire pump in a sprinkler system?

• A. To provide emergency lighting in the system
• B. To provide additional pressure and flow when the normal water supply is inadequate
• C. To extinguish fires directly
• D. To monitor water quality in the system

Answer: (B)

A fire pump plays a critical role in ensuring that a sprinkler system functions effectively, especially when the regular water supply is insufficient in terms of pressure or flow rate. Sprinkler systems depend on adequate water supply to activate and suppress a fire before it spreads. When the pressure from the municipal water supply or another source is inadequate to meet the demands of the sprinkler system — typically due to building height, distance from the water source, or other factors — the fire pump takes over to boost the water pressure and provide the necessary flow. This enhancement of pressure and flow is vital for ensuring that all sprinkler heads activate effectively and that the system can deliver the required amount of water to combat a fire effectively. Therefore, the primary function of a fire pump in a sprinkler system is indeed to provide that additional pressure and flow, reinforcing the system's ability to protect life and property from fire hazards.
