I seem to recall on this forum discussion that a CA state division required 
heads above ceilings in what we would consider non-combustible construction.  
Something like full ACT(no clouds, gaps etc.), wire here and there, lighting in 
ACT, steel duct work and plumbing, occasional 2'x2' return opening to plenum in 
ACT, concrete deck and steel bar joists would still need sprinklers.  Is this 
the people who govern schools, healthcare or am I miss-remembering?
