DRY SYSTEM LIMITATION
DRY SYSTEM LIMITATION
(OP)
Good Morning
I just got a phone call from a friend telling that one of his clients has an issue. Is a day care with a dry system. It has being like that for years and now the fire sub code tells the day care they can not have a dry system in a day care.
The dry system takes care of the day care and then goes into other two spaces. Day care is heated. AHJ requested the day care to be wet and not dry.
Can anybody tell me why? Is there a particular reason?

RE: DRY SYSTEM LIMITATION
ask the nice ahj for a code reference, or if some other agency is requreing this, something offical
and not because I said so
I take it the freind is a sprinler contractor???
also, may want to make sure of what is being required, if this is a pass on message
RE: DRY SYSTEM LIMITATION
I will certainly post his excuse here. LOL
RE: DRY SYSTEM LIMITATION
some reason a dry system was put in in the first place!!!!!!!

It could be that they are worried about trip times as to why they don't want a dry system.

Have you heard of the phrase "Pre-existing non-conforming"
RE: DRY SYSTEM LIMITATION
my version is that a something has been there fore awhile, and in today's codes would not be legal for certain reasons, and have not heard the term used with fire protection systems
have heard that it meet code/ standard when installed but does not meet code/standard today, for fire protection systems
I would highly push for black and white from some ahj code, ordinace, etc... before I spent any money!!!!!!!!!!!!!!
I am wondering since it is a strip center if one of the other businesses is pushing the requirement??? and the day care is stuck in the middle?????
it seems like one reason is a storage business, which might not be able to use a dry pipe????
seems like there is something going on and we do not have the enitre story, where is Paul Harvey when you need him???
RE: DRY SYSTEM LIMITATION
NFPA 101 for new day care does not require sprinklers unless there is a "mini-atrium". Even if it did, it wouldn't specify dry vs wet. It would just reference that an NFPA 13 system is required, and
I think it is safe to assume the IFC is similiar.
Could it be that some wet-behind the ears type put in a dry gridded system? And since the pipe is gridded, the official is requiring it to be retro-fit to be wet?
Nah, more than like the AHJ is reading his SHOULDs as being SHALLs. (A.7.2).
If by some change this is for some branch of the federal government, then wet is most likely required, just depends on what entity it is since they can all have different criteria. It could also be some other local requirements beyond NFPA 13.
