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...
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.
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).
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...
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.

I was wondering about Covered patios. I have been looking into the requirements about when they are required. I hear this both ways about when they are or are not required, and I can't find anything in NFPA 13. Am I just missing it?
i use the laica d3 has a longer distance it can handle.
GPS will not work well for our application within buildings GPS is accurate with a line of sight to the sky,
That requires a calculation big time, unless there was a huge safety factor or designed to handle that demand it may not work.
Additionally just shifting one of the outlets to a new mechanical tee would take some demand off that junction but just a sliver, try that alteration in your...
Make sure that the reduced area is also permitted within the local codes because I have run into exceptions that don't allow for certain occupancies to take advantage of this quick response area reduction.
