NFPA 13 Installation Kits
NFPA 13 is the master standard for new commercial fire sprinkler installation. Every hanger spacing, every head temperature rating, every main size is tied to Chapter 9 calculations. Installation kits simplify the close-out by pre-packaging the hardware contractors actually need.
Kits in this collection cover commissioning assemblies (flow test hardware plus certification paperwork), hanger kits with NFPA-compliant spacing guides, and acceptance test bundles that pre-fill the AHJ paperwork.
For retrofits and residential work, see the NFPA 13D retrofit collection. For high-rise commercial work, combine with a high-rise kit to cover standpipes and zone calibration simultaneously.
Frequently Asked Questions
What does NFPA 13 cover?
NFPA 13 is the Standard for the Installation of Sprinkler Systems. It covers new commercial and industrial sprinkler installs: pipe sizing, head spacing, water supply, hanger support, and acceptance testing.
What's in an NFPA 13 installation kit?
A commissioning assembly (flow-test hardware), acceptance test documentation, hanger spacing guide, and certificate packages for the AHJ. Some kits add torque wrenches and drop-ceiling fastener sets.
What's the difference between NFPA 13 and NFPA 13D?
NFPA 13 covers commercial, industrial, and multi-family buildings. NFPA 13D covers one- and two-family dwellings with relaxed water supply and hanger rules designed for residential plumbing.
Does NFPA 13 require an acceptance test?
Yes. Chapter 28 requires a 200 psi hydrostatic test for two hours, a main drain test, and a visual inspection with the AHJ present. Installation kits include the paperwork for all three.
