If it's a head where the SR and QR are on the same cut that ought to be good enough. If it's not I'd call the MFG's tech support and let them iron it out. If you went the other way one could argue you have to make sure a QR exemption wasn't taken but going SR to QR the only thing that should matter to anyone is the K factor, everything else is irrelevant as long as the heads are listed for the occupancy.

We changed 20 SR heads in one compartment with new QR heads because they were painted or damaged and now he wants calcs because we did not replace them with exactly the same thing. He finally said that if we could show him they were identical except for response time he would allow them.
