How does NFPA 13 address the issue of system interconnections?

• A. All systems must be interconnected properly for effective hydraulic performance
• B. Each system operates independently for maximum pressure control
• C. Interconnections are only necessary for large buildings
• D. Only fire pumps need to be interconnected

Answer: (A)

The standard addresses system interconnections by emphasizing that proper interconnection is essential for achieving effective hydraulic performance across sprinkler systems. By ensuring that systems are interconnected appropriately, it allows for a more reliable operation, especially during fire scenarios where multiple systems may need to work together. Proper interconnections support the distribution of water supply and pressure, ensuring that all areas of the building receive adequate fire protection coverage without compromising system efficiency or effectiveness. This requirement reflects the understanding that in many instances, sprinkler systems may serve different areas within large buildings or multiple structures on a property, and interconnected systems can enhance overall performance and responsiveness in the event of a fire. By adhering to this principle, installations can better manage the hydraulic conditions required for the various components of the system to function effectively, thereby improving life safety and property protection outcomes.
