Thom, There is no question in my mind that you are correct on both issues here. I do have a 2007 13D & 13R handbook just so you know that these are available. Annex-"6.8.2 It is only the intent of NFPA 13R to reference the sprinkler discharge (flow and peressure), number of design sprinklers, and position of sprinklers (distance from walls, ceilings, and other sprinklers) requirements of NFPA 13. Other rules from NFPA 13 such as sprinklering of combustible concealed spaces, hose stream demand, and water supply duration are not intended to be referenced by 6.8.2 to apply to those systems or portions of systems that are outside the dwelling unit but have been determined to be considered residntial orincidental to residential and within the scope of this standard." I believe that this is saying just what you are.

Question has arisen about the meaning of 6.8.2 Design Criteria outside of the dwelling unit. Short version "Protect as per 13." AHJ says that means protect the pool area using 3000 SF design area @ 0.10 and (Here's where we differ seriously) Protect the attic wood truss space above. I believe the intent is that the spaces that would be exempt from sprinkler protection in 13R remain exempt, and only those areas which don't fit the residential requirements of 13R must be protected by as if you were applying 13. So attics, crawl spaces and concealed combustible spaces remain unprotected. Is this how you all see it. (I even question the 3000 SF requirement, because the spaces that drive the 3000 are outside the scope of 13R, and therefore should not affect the areas of 13R that require 13 protection.) Any ideas or comments appreciated. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.
