Brian, You could use a non-ESFR sprinkler like the Tyco K17-231 standard response, standard coverage sprinkler. It comes in both upright and pendent. Area density method with a .60/2000. Then the rules for ESFR do not apply.

We're installing a new system in an existing warehouse that has 22" deep concrete tee's, 48" stem to stem. The AHJ wants it designed for Group A plastics, rack/cartoned/expanded. I'm looking a NFPA-13 (2013) 17.2.3.1 using K17's @ 35psi. My thought is that ESFR heads will be required in every pocket per 8.12.4.1.6, 14.2.4.1, & 14.2.4.3. Am I on the right track?
