Perhaps a different approach would be permitted? FM no longer categorise heads CMSA/ESFR/CMDA, they are storage or non-storage. So, yes, I think these heads are generally suitable for storage. Typically the ESFR heads are considered quick response and the CMSA standard response for the FM data sheets. Many manufacturers have had their heads tested for the FM Data Sheet 8-9.
Regarding idle pallet storage, we learnt that FM use plastic pallets in their tests for their unexpanded plastics category. Our sprinkler standard is currently under review and the draft proposes that idle pallets be treated this way. Perhaps your AHJ would accept FM design criteria, or accept idle pallets be treated as unexpanded plastics and use NFPA criteria as applicable?

Ron Fletcher Aero Automatic -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Dewayne Martinez Sent: Wednesday, November 14, 2012 7:42 AM To: SprinklerFORUM Subject: CMSA for an density/area application NFPA 13 (07ed) One of my salesmen has the following "idea" for the protection of 20ft idol wood pallet storage on the floor for a building with a 25ft deck. Use a K25 CMSA sprinkler (listed as a EC at 14x14) as a CMDA sprinkler and use a .6/2000 density as per 12.12.1.2(a). He cannot use this head as a CMSA sprinkler because it is not listed for idol pallet storage. I told him he could not per 8.4.9 but he wanted me to check anyway. What does the forum think?
