Hi I am an architect in Ontario and the Building inspector in one of our projects has been asking for 3m protection of the standpipe run from the sprinkler room to the vertical run at the sprinklered underground garage. The way I read the new NFPA 14 Horizontal standpipe for system II does not need to be protected from fire, only the vertical portion that goes floor to floor.
Please comment and kindly let me know if there is any back up document from NFPA 14 on this scenario.
Thank you for your time.
