NFPA 418 - STANDARD FOR HELIPORTS

NFPA 418 - STANDARD FOR HELIPORTS

(OP)
Hi everyone,
I have to do a schematic design for a helipad foam-water system with oscillating monitors. The helipad is located on the roof  of a 6 story building. The building has a combined sprinkler/standpipe system. The question is: can I connect the helipad deluge system to the combined riser and size the pump for the greatest demand between standpipe and deluge system? I couldn’t find anything in NFPA 418. Any ideas?

RE: NFPA 418 - STANDARD FOR HELIPORTS

Try looking in NFPA 13 (sprinklers) and 14 (standpipes) to see if they prohibit this.  I suspect if hydraulic calculations support the use, you should be able to get it approved.  Another option is to discuss with the AHJ.
