By their very definition, residential sprinklers are fast response. Check under definitions, 3.6.4.8 Residential Sprinkler. A type of fast-response sprin-kler having a thermal element with an RTI of 50 (meters-seconds)1/2 or less, that has been specifically investigated forits ability to enhance survivability in the room of fire origin,and that is listed for use in the protection of dwelling units.

It is my belief that all residential fire sprinklers are made of quick response elements. This is due to the fact that quick response gears towards a faster Response Time Index (RTI) and gears towards wetting the walls to delay the fire from spreading. This is to allow occupants to evacuate. Standard response gears more towards the suppression side and more water is displaced at the base of the fire. Quick Response deals more with life safety, so anytime you have to follow NFPA 101 (Residential, office spaces, dorms) you will find quick response. Standard response is more towards factory's and industrial.
