I think there is a seminar tomorrow at the NFPA
conference in Boston that may touch on this. If you start peddling now......

Thank you for such a good question and answer.
Are there any comments or studies about the
influence of cold air [air conditioning ]
blowing air at the sprinkler? Would the cold air
delay the response of the sprinkler?

Typical ceiling diffuser is blowing air downward, (actually in an
mbrella type pattern, but who's to argue) A sidewall or side of duct
ounted type would be considered horizontal.
By the definition and the directions in the table it looks like you need
o be at least 1'-0" from the edge of the diffuser so if you're 1'-1"
ou should be good to go with an Ordinary Temp. You're mighty close
hough.

ubject: Sprinklers located next to diffusers
Looking at Table 8.3.2.5a in 13-2002 there is a downward and horizontal
iffuser. For the standard 2x2 diffuser in a suspended ceiling which is
he correct to use. It is blowing air downward and horizontal? Can I
nstall an ordinary temp pendant sprinkler 1'-1" away from one of these
iffusers?
Thanks
