Distance between SPK

[Bassem_ABID]

In accordance widh the NFPA 13 standard (paragraph 9.3.5.3.1), what's the distance between SPK when a draft curtain exists between them ? It is 1.8 or 3.6 m.

 

[UFT12]

The situation described in 9.3.5 is not for draft curtains between sprinklers, rather parallel. If this is your case, see figure A.9.3.5 for the maximum distance.

Hello thank's for the answear, but if a draft curtain with 2 m of depth was between two sprinklers what's the distance between them ? and the distance between the sprinklers and the ceiling ? the draft curtain will be considered as a wall or beam or it is a special case ?

 

[UFT12]

Then the beam rule applies. See the requirements of 10.2.7.

I think that the answer is in the standard NFPA 204 there is a chapter for this topic when the sprinklers are combined with draft curtain.

1. What kind of sprinkler is it??? Standard or other?

2. What is the maximum spacing per the listing?

3. What is the spacing layout for this design system??

If just a general question,,, than the answer can vary
