I thought it was that clear as well, but a large complex has been denied
because of intermediate temp sprinklers in dwelling unit mechanical
closets and laundry rooms. I just wanted to make sure I wasn't way off
base on this.
I am submitting an AFSA informal interpretation, as well as a technical
question to NFPA to get the answer to provide to this plan reviewer as well.

How do you mess up:
8.3.2.1 Unless the requirements of 8.3.2.2, 8.3.2.3, 8.3.2.4, or 8.3.2.5 are
met, ordinary and intermediate-temperature sprinklers shall be used throughout
buildings.
Intermediate can be used throughout unless other sections require a different
temperature rating.

Subject: Intermediate temperature sprinklers
We are designing an apartment complex per NFPA 13 requirements. Is it
permissible to install intermediate temperature sprinklers throughout all
spaces (except those that would specifically require a high temp sprinkler due
to other sections)?
The specific question arises because we have ordinary temperature sprinklers
throughout most areas, and intermediate temp sprinklers in mechanical closets
and laundry rooms in the dwelling units. The AHJ states that since the areas
(mech closets and laundry areas in the dwelling units) are conditioned spaces,
that we must use ordinary temperature rated sprinklers. He states that Table
8.3.2.5(c) over-rides the flexibility provided by 8.3.2.1 which allows ordinary
or intermediate temp sprinklers throughout buildings.
This has been common practice to install the intermediate temp sprinklers in
these areas. This is the first time that this plan reviewer has ever brought
this up. Some contractors in this area are moving toward intermediate temp
sprinklers throughout in residential areas for various reasons.
