New Code for AZ???

[JASON SIEBELS]

Good morning,
I have noticed that my last 2 project are requiring RTU's to have global shut down upon activation of sprinkler system. Is this a new code in AZ? Mostly, up until this point, the requirement for global shutdown of air handlers was controlled by duct detectors. Having the shutdown now initiated by the sprinkler system "popping" is rather new. I have not seen anything in NFPA72, but I could have missed it. Any input is appreciated.
Thank you in advance,

Have you asked the AHJ for specifics on
the "global shut down" of the RTU's ?

Jason, ...I recommend that you contact the AHJ
in which your project is located, and ask the
questions you have asked on this Forum........You
[ should ] get a more direct and accurate answer.
