Forumities, This has likely been previously addressed, but it's just not coming back to me . . .
I've got an existing ordinary hazard area that is protected by existing EC sprinklers. The existing EC sprinklers have fast response (3mm) elements and are listed as standard-response for the 20'x20' spacing they are protecting. If these sprinklers were protecting an area of 14' x 14', they would be listed as quick-response. I need to add a couple standard-coverage sprinklers due to wall changes. Should the new standard-coverage sprinklers be quick-response, or standard-response? NFPA 13 (2019) section 9.4.3.5 gives me guidance if I were adding an identical EC sprinkler, but that's not what's happening.
