Vince, Re FM's 1.4, as far as I can tell, for ceiling slopes of 1/12 and less, 1.2, and if greater, 1.4. For number of heads, last one I did was 6, 3 on two lines, so 1.2 and 1.4 was N/A. FM was the only AHJ though so there was no question. If FM is not the only AHJ in your case be careful! (know what I mean?)

Is the shape factor different than the usual 1.2 or 1.4? Did I read here that FM scrapped their 1.4? Help,help & thanks!
