I always went by having to take the supply for the FDC, from a tee between the system control valve, and the dry pipe valve. (On a single dry pipe system). NFPA #13 - 2010, 8.17.2.4.2(2) states it this way. 8.17.2.4.1.2 says that it can be connected to the main piping on the system it serves, ie: the end of a cross main. I always believed that taking off the end of the cross main only applied to wet pipe systems. I am not agreeing with somebody that says that it can come off the end of the main on a dry system also. What am I missing, or have I been wrong?
