EXACTLY what I was thinking. I wonder why NFPA just doesn't say to use
QRs to make the draft
curtain go away.
Thanks, Kyle!

We dealt with this recently where the argument was how to define
“adjacent” sprinklers and whether a mezzanine some 10-plus feet below
the ESFR system should be considered adjacent. I’m not sure if there
was a consensus. But that was a concern because the heads under the
mezzanine were going to be standard response. I don’t see why you
would be worried with QR sprinklers.
See 8.4.6.4.1, where it specifically addresses “where ESFR sprinkler
systems are installed adjacent to sprinkler systems with
STANDARD-RESPONSE sprinklers…”

Good morning, forum -
Looking for opinion or code reference.
Is a draft curtain required?
ESFR system at roof 25 ft
Mezzanine at 12 ft, opens out to high roof
Can standard qr heads be used under the mezzanine without a draft curtain?
thanks, Vince
