I assume you are talking about '02-8.14.1.6. The other issue is the members
are capable of trapping heat. The annex section says more than 2" top cord.
Around here these are usually (but not always) 2"x materials on the flat and
thus wouldn't trap heat by the criteria and thus no listed sprinklers
required. Also there is a combustible upper surface part. Use fire treated
plywood and the listed head aren't required. It's not just a 36" test.
But otherwise like Ray says either follow the listing or reduced remote
area.

Bobby,
If the area in the floor/ceiling space is a "horizontal combustible
conceled space" 36" of less in height (and I presume they are),
you must use a LISTED sprinkler for this space and abide by all
requirements of the sprinkler's listings, including appropriate
compartmentalization.
If the area is more than 36" in height then you can utilize the area
reduction allowances as long as you meet all of the conditions per
NFPA-13, as previously indicated by Matthew.

Yes as far as I see. As long as all conditions are met, there are no
other restrictions mentioned.
