The book shows single preaction systems fdc on the system side with a check valve after fdc supply. Which means the trim to the valve must connect above that check valve. (Never ran into this situation). I suppose the same could be done with a solenoid released dry valve.

I have been in this industry since 1969, and FDC's have NEVER been allowed on the system side of the dry pipe valve.
