Mark, What is the nature of the construction of the 5-sided container? (metal? Wire, plate, open frame?) Also, what is a ' 3 1/2" DAT'? Are the container stacks in single/double/multiple rows?
I am not familiar with this sort of storage facility.

Also should mention that the owners/arch would like it to be protected with a pre-action system. On the buildings that you installed in racks, what section of the code did you use to place your sprinklers/piping? These racks are just a bunch of 5 sided non-com containers that hold books for the library and there is only 1" of space between the top of one container and the bottom of the container above it. Every 4-8 of these containers there is a 3-1/2" DAT. NFPA does not really call out anything for this type of rack so right now I'm looking at section 16.3 (NFPA 13 2010) for class 1-4 commodities stored in racks over 25'-0". -----Original Message----- From: sprinklerforum-boun...@firesprinkler.org [mailto:sprinklerforum-boun...@firesprinkler.org] On Behalf Of Ronl.Fletcher Sent: Wednesday, October 26, 2011 10:15 AM To: sprinklerforum@firesprinkler.org Subject: RE: Automatic Storage Retrieval System (ASRS) Sounds like you could use the Reliable K25 ESFR at the roof, it is good to 48 ft. Just be careful that you have the 36" clear from top of storage to the sprinkler. I don't see why you would need inrack sprinklers. We have done many ASRS buildings but they have all been 80-110 ft. high so we had to use inracks.

I have a 46'-0" tall ASRS and we are trying to figure out the correct way to protect this. Sent info to NFPA for an informal interpretation and not much help there and also talked with some FM people and the best they could come up with is that they think it needs in-racks but could not point to an acceptable table or figure for placement of said sprinklers. The rack manufacturer has done almost 20 of these racks and has not had in-racks installed. Any insight on this would be greatly appreciated. mja...@brigadefire.com <mailto:mja...@brigadefire.com> www.brigadefire.com <http://www.brigadefire.com/> -------------- next part -------------- An HTML attachment was scrubbed...
