Yes, keep the overall picture in mind. RTI is only one aspect. As others
have said, as more sprinklers
all i got is some numbers:
27' ceiling height, 9 deflector distance, couch on fire in the middle
of a large, open furniture showroom---
286F, standard response- activation time = 188 seconds
286F, quick response- activation time = 172 seconds
212F, standard response- activation time = 97
SoHigh release vertical heat plume hitting ceiling and starting to
spread out, immediate ring opens starts to cool fire but intermediate heads
in second ring open, dropping flow to first ring, but doing nothing to cool
fire, the third ring with even worse results. My understanding of QR
!EXACTLY! Ron :)
I never try to predict anything, per se, I try to find the DIFFERENCE
between scenarios, in this case the same Ceiling Height and Heat
Release Rate versus sprinkler Temp and RTI. For a benchmark, I found
the steady state HRR that would activate a 286 SR in ~180 seconds,

The 2002 version of 8.3.2.3 differs from 2010 only by the inclusion of
intermediate temp in the text. The store will be display in room style

Snake oil sales talk
Methinks he is picking nits.
On what basis is he requiring intermediate temperature heads? Does he have
evidence that the maximum ceiling temperature exceeds 100 degF? How does he
know it is 150 degF and not 225 degF? (Table 6.2.5.1) It sounds to me like he
is making something up just because
as Todd already said, it is explicitly allowed by 8.3.2.3 unless the
AHJ is trying to call it a light hazard occupancy.
