When using ESFR sprinklers to protect a low-piled storage/miscellaneous storage that is equivalent to an OH2 curve: what minimum operating pressure for the sprinkler do you use?
Do you just go by the nearest chart in the later storage chapters and go with the closest to your situation (so like 35 for a K16.8 and 15 psi for a K22)?
Or do you just go with 7 psi like you do a standard sprinkler?
The listings do not specify a minimum operating pressure except to say "per NFPA 13". Code references are always appreciated. Thank you for your time.
