UL1626 identifies the testing parameters but it does not identify any
limits on the installation. That is left up to the manufacturer's
cut sheet and NFPA 13 / R / D.

Dear All,
Let me clarify that in this situation the room has a flat ceiling
above. I
understand the intent of wall wetting and agree that regardless of
height
there still will be the net effect of wall wetting. It just seems
to me
that the prevention of flashover is better served from 8-10 feet
AFF than 18
feet above.
I guess my question really is just for point of knowledge, does UL1626
address ceiling height at all or is this just one of those things
that 'just
is'. I looked into getting access to the UL1626 document but it's not
fiscally possible.
Thanks again.
Dave,
