Sprinkler above false ceiling

[crb7]

Hi guys
May you tell me the height above false ceilings which needs sprinkler?
Im working on a project which this height is 2.2m.

The basic premise in NFPA 13 is that all areas are provided with protection. Start with that. Then, if you have a space that meets the criteria to eliminate sprinklers, that will be your answer.

Just for the sake of the discussion, may I add that NFPA 13 does not impose any limitation for clearance of concealed spaces. However, that applies in EU which regulations limit the height of clearance among other criteria such as combustibility of the space itself. The union of insurers (CEA or VdS) impose also limitations based on fire loads within (MJ/kg).

You should describe in more details the construction features of the building, equipment found in the 2.2m space, occupancy of the floors below and above the suspended ceiling so that some thoughts or argument with the owner about the need for sprinkler protection above the suspended ceiling. We all know that the NFPA provides minimal guidance but also logic has to prevail regardless of the codes. State fire marshal or local fire department also have a say so on the matter so consult with them.
