And this seems to be the difference between the Classification of the Occupancy/Commodity (hard part performed by EOR) and figuring out what sprinkler and spacing to use in a particular compartment with clouds, soffits, skylights, beams, joists, hidden spaces, piping configuration, hanger placement, bracing, hydraulic calcs, submittals, etc. (easy part performed by sprinkler designer/contractor).
Just joking about who has the easy part. Bill Brooks (Member) William N. Brooks P.E.

I could see these EC sprinklers being used as both 20'x20' and 14'x14' in the same compartment in order to protect odd-ball areas. Then adding new SC sprinklers and deciding if they should be QR or SR gets more complicated. I was hoping 13 would provide guidance.

If the 3mm bulbs are spaced at SR, we utilize SR 5mm bulbs for adjacent standard coverage sprinklers.

Is there an AHJ you can lean on? That's what I would approach them with as far as logic.

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?
