13 R hotel system
13 R hotel system
(OP)
In the corridor, they have a sheet rock enclosure walls and ceiling.
Below the sheet rock about two feet they installed wood 2X4's across the corridor and the length of the corridor. Than they will attach sheet rock to the bottom of the 2x4's
In this void area is duct and can lights.
Would under 6.8.5 nfpa 13R 2002 require sprinklers in the void area, or would you call it limited combustible, ot something close to 6.8.5 langage??
6.8.5 Sprinklers shall not be required in attics, penthouse equipment rooms, elevator machine rooms, concealed spaces dedicated exclusively to and containing only dwelling unit ventilation equipment, crawl spaces, floor/ceiling spaces, elevator shafts, and other concealed spaces that are not used or intended for living purposes or storage and do not contain fuel-fired equipment.

Is this project NFPA 13 or 13R?
If it is NFPA 13, then if the wood used is not treated lumber in accordance with the definition in NFPA 13 for "limited combustible", then it is combustible. Since they are framing and creating a concealed space, and using combustible materials, this is a combustible concealed space, and since it is 2 feet deep, it will very difficult to make this configuration match any of the exceptions allowing omission of sprinklers.
If this is an NFPA 13R project, then concealed spaces are not a consideration in the current NFPA 13R document, when using residential sprinklers, or quick response sprinkler (when allowed).

I fail to see the hints. What I see is concealed spaces containing fuel fired equipment will require sprinklers and that really isn't a hint.
RE: 13 R hotel system
I guess I am reading this backwards to say if you have a concelaed space that has other than dwelling unit ventalation, such as can lights????? need to be sprinkled????
I guess I wonder why they would not just say concealed spaces need no sprinklers, like they do for attics??
Maybe I just answered my own question if you do not sprinkle a 10000 sq ft toothpick attic than why sprinkle a small concealed space.
anyway ,Merry CHRISTmas
