If you think about it, as an example, you install 165 deg sprinklers in everything from an office to a cooler and anything in between. If there was concern over the cooler ambient temperature of the space affecting the sprinkler response I'm sure NFPA and FM along with UL would have some commentary on it. So to install it near the diffuser as long as it meets the distance requirements of NFPA 13, should cause no additional concern.

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? mario berrios [EMAIL PROTECTED] -----Original Message----- From: [EMAIL PROTECTED] To: [email protected] Sent: Tue, 8 May 2007 3:10 pm Subject: RE: Sprinklers located next to diffusers 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. raig L.

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?
