Which standard governs the installation of sprinkler systems?

• A. NFPA 25
• B. Sprinkler Installation Guidelines
• C. NFPA 13
• D. NFPA 70

Answer: (C)

NFPA 13 is the standard that governs how sprinkler systems are installed. It lays out the requirements for design, layout, materials, piping, sprinkler head placement, water supply, and installation practices, along with testing and acceptance procedures. This is the framework installers rely on to ensure reliable, code-compliant performance of automatic sprinkler systems. For low-rise residential buildings, NFPA 13R addresses residential-specific needs, but it still references NFPA 13 for the fundamental installation details. NFPA 25, by contrast, covers inspection, testing, and maintenance after installation, not the installation itself. NFPA 70 is the electrical code, which governs electrical systems, not sprinkler installation. There isn’t an official standard called “Sprinkler Installation Guidelines,” so that option isn’t applicable.
