Brian look back at the archives, in 13R there are situations where full
attic systems are required. It has to do with the building code, and
separations in the attic to sub divide the space at all hall and party
walls. If you only do the 3000 or 6000 Sf smoke partitions you'll end up
with the attic
Thanks!
Looks like there are also times in a 13R system that they can be eliminated.

I don't spend allot of time in 13D or 13R but I seem to remember that one
of them does not require sprinklers in the attic, can someone point me in
the right direction?
Thanks!

Oregon does not require special licensing for forward flow testing.
I think Doug was referring to backflow testing, not forward flow testing.
However, NFPA 25 does require a backflow function test after the forward
flow test is completed.

IV would appear reasonable, look at the items and consider the makeup of each.
While mowers and weedeaters are primarily metal, based on the NFPA 13 def. of

require 1/4 of a pound (12 oz.) of plastics to achieve the 5%.
Yes I know, I understand that there is a 15% allowance for plastics in Class
IV. How do you reasonably take a varied mix like this and assign a % to it.

If this was a hospital or class room with VAV boxes and fans above the
