The 1-12 inches is about where the head is installed not where it is required. It says ever time you install a sprinkler it has to be 1-12 inches below the ceiling to work. It is not saying anything about the placement in terms of different ceilings. The less than 36 in is allowing you to treat...

Stookey I still see some potential use of NFPA 13 hose valves in industrial settings which is probably why they haven't been so easy to kill off.

I don't do building inspections but i have checked the rating or two on a fire door or two but i never thought about the glass being replaced and checking the rating.

matt i think the chance of a variance has to do with not only the report but the comfort level of the fire official with their knowledge of fire protection.

then it looks like you should be able to install a hose valve per the nfpa 13, which requires it to be from an adjacent system

You referenced 7.10.1.1.1 of the 2010/13 edition. The AHJ has adopted 2007 which reads slightly differently (the text is in my first post). The problem is 7.3.2.2 which allows for one party to argue it's there for testing.

Te most NFPA 13 would say something regarding using the equipment as listed. So you can ask them to can show it listed for this handcuffing (which I doubt).

Is it just me or I don't see NFPA 219 http://www.nfpa.org/aboutthecodes/list_of_codes_and_standards.asp

This is a question about which hose connections are required to flow on the most remote standpipe. One party is arguing that you calc the top two as defined by the top hose valve + the testing hose valve while the other party defines it as the top two excluding the testing valve (as in the top...

still not following...

There is not enough information in here to tell you a number. But I can tell you that you need to know how much gas is being produced. How much ventilation is occurring, mechanically or naturally? The volume of the space?

If you mean zone by seperate fire sprinkler systems? You zone the building based off max sq. footage, there can be two systems in one open area, or it crosses a wall etc. The flow of the pump only needs to be able to supply the most demanding area calc. so you should check each system but the...

In the 2006 International Building Code Section 905.4 Location of Class I standpipe hose connections. Class I standpipe hose connections shall be provided in all of the following locations: 2. On each side of the wall adjacent to the exit opening of a horizontal exit. Exception: Where floor...

Sorry this is the safety factor for fire sprinkler systems.

I was looking in the code trying to reference the section of code which states safety factor. Can anyone give me a hand on this reference?
