It was always the intent that you could not mix sprinkler types (since there has never been a stated means of combining different design basis). The source of the problem was that the 2010 ed and earlier wording that was an archaic left-over when referring to the sprinkler as a fast response type (see 8.4.5.3). Thus some assumed that meant any type of fast response sprinkler so I guess an ESFR sprinkler would fit that bill. The problem becomes apparent when attempting to mix the different design basis.
