----------------- TECHNICAL UPDATE JUNE 9, 2010 ----------------- “We are performing sprinkler inspections on older residential type systems. We have noted on our inspection form that no hydraulic plate is on the system. When the inspection is reviewed by the fire marshal, they are requesting a sign. Are hydraulic signs required per NFPA 13D or NFPA 25?” We have reviewed the 2008 Edition of NFPA 25 and the 2010 Edition of NFPA 13D as the applicable standards. Our informal interpretation is that the standards do not require a hydraulic data plate for NFPA 13D applications. The requirement for a hydraulic data plate or placard (as often called but technically labeled the Hydraulic Design Information Sign) is part of NFPA 13 (section 24.5). NFPA 13D has no such requirement. It's also interesting to note that IFC section 901.6.1 requires inspections per NFPA 25. NFPA 13D systems are explicitly excluded from the scope of NFPA 25 according to section 1.1.3. As such, inspections aren't even required by the codes. However, keep in mind in the future that there will be a change in the 2012 Edition of the IBC for NFPA 13D systems classified as Institutional or “I” occupancies. Institutional or “I” occupancies using the NFPA 13D allowance in IBC will require a hydraulic placard and inspection as if it was a NFPA 13R system. ----------------- Technical Update is prepared by the Technical Services Dept. of the AFSA: Vice President of Engineering and Technical Services Roland Huggins, a PE registered in fire protection engineering; Phill Brown, a NICET IV certified automatic sprinkler technician and NFPA Certified Fire Protection Specialist (CFPS) and Tom Wellen, a degreed fire protection engineering technologist.
