I am looking at a space that is using ESFR to protect an ordinary hazard use. In a couple of spots, there are very high heat sources (400+ degrees) that would exceed the temperature rating of any ESFR head. NFPA 13 8.3.3.3 (2010 & 2013 ed) says that "where there is no listed quick-response sprinklers in the temperature range required, standard-response sprinklers shall be permitted to be used."
With that in mind, would it be acceptable (code-compliant) to simply switch out the ESFR heads for high-temp, standard response, standard spray heads? The resulting system could still easily supply OH2. This would be about 4 heads (out of 2500) spaced apart from one another... not enough to really be considered an 'adjacent system' per NFPA 13 8.4.6.4.1 It seems to fit the letter of the code - and the intent of providing OH coverage for this area(actually way more).
