Situation about riser and crossmain
Situation about riser and crossmain
(OP)
Good day everyone, i have a situation about the building. just open the attachment. hope someone can help me. you see in the 4th floor of this building there is only a partial area. the left side and the right. and the middle is the roof for the third floor. my problem is that if a run a crossmain directly to the left side it would be too long. 66meter. im thinking to connect the left side to the crossmain for the third floor. is that a valid idea or still the standard nfpa? please help me. thanks a lot.





RE: Situation about riser and crossmain
If the lower levels are less than the maximum (I think it is 52,000 sf), the sprinklers on those floors could be from either riser.
That is how I would do it.
RE: Situation about riser and crossmain
That is not a good idea, that is a different zone.
Put riser on both side of the building instead.

Also, if you did run the 66 meters across the roof, How do you comply with protecting the pipe from not only freezing, but fire. Also located in 8.16?
