Which standard is the primary reference for installing sprinkler systems?

• A. NFPA 25
• B. NFPA 101
• C. NFPA 13
• D. NFPA 220

Answer: (C)

NFPA 13 is the standard that lays out the requirements for installing sprinkler systems. It covers how the system should be designed, where pipes and sprinklers go, how they’re spaced, what materials and fittings to use, how the system is supported and braced, and how hydraulic calculations and testing are performed before the system is put into service. Because of this comprehensive scope, NFPA 13 serves as the primary reference for the actual installation process. Other standards serve different purposes. NFPA 25 focuses on inspecting, testing, and maintaining sprinkler systems after they're installed, NFPA 101 addresses life safety and means of egress, and NFPA 220 deals with fire resistance ratings of building assemblies rather than sprinkler installation. In the context of residential low-rise systems, NFPA 13R handles residential-specific provisions, but the installation details themselves are anchored in NFPA 13.
