yes it is a military dining facility; ordinary hazard group .15/3000 ft with hose demand of 500GPM, these include small storage and dinning areas. Ordinary hazard group 2 areas, .2/3000 ft with hose demand of 500 GPM. These areas include the kitchen cooking and prep areas.
Also just as a side...
Sprinklerdesighner,
I'll do my best to give you the numbers you can use to work with, hopefully it will be enough.
1. Size and type of main: they will tap into a 6 inch main, the main is schedule 40 PVC (plastic pipe), the main system is a looped type.
2.The facility is a dinning hall...
Is there a simple formula or website for the calcs?
It looks to me that in my case that NFPA 13, 15.1.3.2 will apply; I would liek to run some rough numbers to see if what the A&E gives me is close.

thanks, I'm not a mechanical PE so I do not know all the ins and outs of hydro calcs, but I suppose they just need to go to a larger pipe size to get the required GPM and pressure at each sprinkler head and to be sure they can certify the system in within code.

ok, thank you.......I just did not know if this was common or out of ordinary, I assume it helps to get the hydraulic numbers and calcs within code.

Single story, and they are still working the numbers, saying they may have to have a pump now, its a commercial cafeteria building, assembly occupancy.

Why would an A&E desighn a sprinkler riser in such a way that the existing water main to tape into is 6 inch, but the A&E is desighning an 8 inch on top of the 6 inch pipe as it enters the facility ?
Is it normal to go from a 6 inch supply line to a 8 inch riser?
If so why?

It will also depend on who t he halon is for; if it is a Govenrment or Federal agency, you may be able to get it for zero dollars.

All the overhead doors, are to rooms that are inside storage rooms, I wish I could post a picture of the bldg and rooms on this.
The overhead rolling doors, will drop if the fire link is fused, and they will also drop down electrinically if the fire is activated or activates.

Let me try briefly explain a little further; I probably should of just ask this from the start.
A storage facility, used for hazardous waste accumalation not limited to battery storage, water reactive corrosives, flammable liquids/solids, ect.. The facility is 1600 sq ft. Built in late 80s...
Stookeyfpe,
That is exaclty how I see it too, I just could not find the wording in NFPA; I will get a hard copy of the IFC paragraphs.
Thank you so much. Now I can have a good weekend!!!!

Does anyone know any further wording in NFPA that talks about any fire protection equipment, device, system, ect...that if installed (no matter when) it must be 100% operational or removed if not needed or required?
The only thing I am coming up with is NFPA 72, paragraph 4.3.1.
Does...
Thank you so much for all the great inputs; are there any "simple" and "easy" books or formulas I can use to give me a ball park estimate of required water supply ?
