In a manufacturing facilty is there a reference for clearance of sprinkler head from ceiling? Is there a min or max distance from ceiling? The facility produces plastic piping

Per NFPA 13, the standard for installation of automatic fire sprinkler systems, in unobstructed construction, the minimum deflector distance from the ceiling is 1" and the maximum is 12". With obstructed construction, you can be 1-6" below the bottom of the beams to a maximum of 22".

I hope that helps to answer your question.

Thanks, I have a ceiling that has 24" steel joists. There is conduit and material (plastic pellet) convey piping running between the structure. Would this mean the sprinkler deflectors can be 6" below the joists?
