Pardon me for making some suggestions to add to your decision making
process.
You did indeed bring the issue to the forum, and you got several angles to
think about, including mine. Far too many times the aspects that I
mentioned are not considered. I simply pointed them out to you.
Is the forum an appropriate place for a negative response such as yours?
No one was "questioning your authority to ask the forum for insight" to make
themselves feel better. Perhaps you should re-read the post. As for
bravado? There are others on this forum than just you, that may appreciate
others' perspectives on issues such as this.
I make NO apologies for this.

I bring this issue like others to the forum for a place to throw out ideas
hoping for feedback
I believe it is important in a forum environment to share ideas with
others who have experienced similar situations
My earlier comments were provided so forum members know what my brain is
thinking
My interpretation is based on reading the code and comments from NFPA
specific as I could get to the issue. No, I did not complete fire tests
or call my local PE for an answer before starting this thread. I did not
know this forum required such high a threshold
Feel free to question my authority to ask the forum for insight if that
makes you feel better. I know that bravado provides absolutely no value
to the forum
Sincerely,
Exceeding my authority but thankful for the forum

I have been watching this thread with interest, and finally have to ask
(and
yes, I am sure this will stir the pot as well)....
This particular issue is one which requires more than just mundane
interpretation of the NFPA 13 standard. Who should be doing the
interpreting??? NICET technicians, or PE"s, or ???
My gut feeling here is that if you choose to support the more liberal
interpretation, that this will NOT require both above and below
protection,
especially without any significant test data to back it up at this point,
that this is not the place for a NICET technician to make this decision,
or
for that matter to try to "sell" it to the local AHJ. Do you really want
that liability? Not to mention whether you are exceeding your "authority"
under NICET rules for practicing engineering?

NFPA 13 2002 Edition - Section 8.14.1.2.2 - "Noncombustible and limited
combustible concealed spaces with limited access and not permitting
occupancy or storage or combustibles shall not require sprinkler
protection. The space shall be considered a concealed space even with
small openings such as those used as return air for a plenum".
Maybe I did not describe correctly the ceiling construction. The ceiling
will be installed throughout the space(s) at the same elevation. The
"openings" are 7" gaps along the perimeter walls or between sections of
the ceiling within the room. This only occurs in a few of the
spaces/rooms and those rooms are separated by full height wall from other
spaces.
I believe the section above may adequately address this issue to the
point
I can meet with AHJ concerning sprinkler protection above the ceiling
space.
