Well, as I mentioned earlier, this particular plan reviewer is typically
very good to work with. After some further discussion, he was willing
to accept the intermediate sprinklers as we intended.
This job is always better when both sides are willing to listen and work
together to achieve the desired result.

It got me thinking, and now I just use standard everywhere.
I mean if you really think about it, something would have to be incredibly
wrong for a dwelling unit laundry room to get over 100° at the ceiling.
This is abnormal.
An outside closet with a hot water heater maybe I could see in certain
areas of the country, but I've been putting 155s in them for a while now.
For non-residential heads, 175s are a PITA to get sometimes as well. They
never seem to be in stock when you need them. I just go to 200s for those
and call it a day.

I tried. The response is that we are required to use the table, and that
governs everything. However, the contractor does not want ordinary temp
sprinklers in this area. So, I am having to track down some
interpretations and such that prove the point.
Gotta love the games we have to play.
I will say that this reviewer is normally very good and quite nice to work
with. Something must have recently happened to cause him to flag this as
an issue.

So ask him where in the table (or the text) it say if you're more than the
minimum distance away for the ordinary temp sprink that you must use an
ordinary temp sprink? He's really reaching.

Subject: Re: Intermediate temperature sprinklers
For example, the plan reviewer is stating that if the sprinkler is >6"
from a furnace or water heater, it MUST be ordinary temp rated.
I understand the standard to state that you can use intermediate or
ordinary
throughout. Table 8.3.2.5(c) just states that if I am within certain
distances to a heat source, I MUST use the intermediate temp sprinkler.
The plan reviewer is reading that if I am more than the minimum distance
away, I MUST use ordinary. He is stating that Table 8.3.2.5(c) over-rides
8.3.2.1.
So, who is correct? That is the question that I need to be able to
resolve
with the plan reviewer.

Table 8.3.2.5(c) gives the minimum distance from various heat sources
for both ordinary and intermediate temp sprinks. I don't see anything
in that table that dictates which sprink temp must be used. Are we
missing something?

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.
