Anthony: The code has never been enforced this way - sprinklers are required to be installed per NFPA 13, with its exceptions noted. (Regarding attics, the term "Attic" is defined in the IBC as, "The space between the ceiling framing of the top story and the underside of the roof." An attic is not a room in that regard.) I think you're "reading further than necessary". 903.3.1.1 states that where sprinklers are required to be installed per this section, sprinklers shall be installed per NFPA 13. 13 includes very specific exceptions for non-combustible concealed spaces such as attics and floor/ceiling interstitial spaces. So, where sprinklers are required, follow 13 and the building is considered "fully sprinklered" per the code.
903.3.1.1.1 goes further, and clarifies the language in both 13 and the IBC that states "all areas" of the building must be protected with sprinklers. In that context, this section expands on the rooms and areas where sprinkler protection can be excluded, but ONLY if detection is provided. I don't believe it has ever been the intent of 903.1.1.1 to supersede the exceptions in 13 for non-combustible concealed spaces. If that was the intent, we would have been putting sprinklers into concealed spaces for years and the NFPA 13 committee would have already harmonized the standard with the code.

Where the provisions of this code require that a building or portion thereof be equipped throughout with an automatic sprinkler system in accordance with this section, sprinklers shall be installed throughout in accordance with NFPA 13 except as provided in Sections 903.3.1.1.1 and 903.3.1.1.2. 903.3.1.1.1 Exempt locations. Automatic sprinklers shall not be required in the following rooms or areas where such rooms or areas are protected with an approved automatic fire detection system in accordance with Section 907.2 that will respond to visible or invisible particles of combustion. Sprinklers shall not be omitted from a room merely because it is damp, of fire-resistance-rated construction or contains electrical equipment. 4.Rooms or areas that are of noncombustible construction with wholly noncombustible contents. This non combustible area above the ceiling is not required to be sprinklered per NFPA 13 but as mentioned in the IBC it's only if the area is protected with approved automatic fire detection system. You could check to see if this area has any smoke detectors and if not use this section to show that the upright protection of a non-combustible area is required per the IBC.

On the upside, more sprinklers are better, and even if not required they can act as detectors in the space. Bottom line is that the AHJ has ultimate decision making authority.

Do not click links or open attachments unless you can confirm the sender and know the content is safe. We installed temporary upright Protection in a partially occupied building during a major renovation. We then came back and dropped pendent heads in the new ceiling. We left the uprights above the new ceiling. Fire inspector says we need to remove the uprights now. Is there a basis for removing these? I realize they are not required but are they permitted to remain? John Irwin
