300 sq. foot safe in 13d system
(OP)
Hi all!
I got a question for ya! I am designing a nfpa 13d fire sprinkler system in a 10,000 sq. ft. vacation home in our area (central washington). Needdless to say the guys got loads of money. I noticed during my survey he has 300 sq. ft safe/room. The walls and ceilings are 10" thick concrete and it has a safe door on it, (like you would find on a heavy duty gun safe or at the bank). The AHJ and I are working on finding out weather or not this is required to be sprinklered. I'm posting this to see if any of you have had experience with anything like this in your yrs of service to the fire sprinkler field. We really don't want to have to core drill the concrete, and we don't really feel like sprinkler coverage is necassary in a concrete room with a heavy duty safe door. Does nfpa 13d (2007) 8.6.5 excuse me of providing caverage on this room. Or would it depend on what is being stored in this room? Any help would be much appreciated.
thank you

A 13D system is basically there to sound an alarm and buy you 10 minutes to get your family out of the house. If the fire is suppressed, that is just a bonus
I have seen some weird things in homes myself. My favorite was the gun range in the home. The AHJ req'd institutional HSW's be put in the gun range. Go figure!

That entire concept of a 10 minute life safety system was gone out the door. I don't mind doing above the minimum, and it is good in some cases. However, I haven't heard of hundreds of people dying in homes with fire sprinklers designed in accordance with NFPA 13D.

do not have 13d in front of me, but would say no
RE: 300 sq. foot safe in 13d system
also maybe use 903.3.1.1 ifc 2003

As far as I know, it is a local ordinance. The contractor I work for in that area states that those are the requirements for the area. So, that is what goes in. The only thing you don't have to protect is the concealed combustible spaces.

Our company is definitely not supportive of this but we are at the mercy of the ahj.
