The confusion is as is often the case the words. That standard response being used for both element and sprinkler listing creates an equivalency in ones head. I’d argue that the fast response element is often found in sprinklers listed as standard resonate but a standard response element is never found in a quick response sprinkler. I’d argue the listing of the sprinkler in the application is driver and that you have a compartment in which all the sprinklers need to be standard response per the rules of their listing(s).
