Fire sprinklers - residential vs. quick response

[TSN79]

I never really understood the difference between these two. I believe I've heard someone say that all residential sprinklers are quick respons sprinklers, but not all quick respons sprinklers are residential sprinklers. Is that accurate? Even if it is I still don't get what differs the two. Hopefully someone here can explain :)

Does the Wikipedia article help?

Actually, no residential sprinklers are quick response and no quick response are residential.​

The definitions of Quick Response, Fast Response and Residential Sprinklers are defined in NFPA standards.

Fast response refers are able to achieve a particular response when tested in a standard test rig. They can do this because they have small heat sensing elements which react to heat quickly.

Quick response sprinklers are a type of fast response sprinklers when installed in particular conditions (e.g. maximum height from the floor, maximum spacing) can be used to reduce the amount of water the sprinkler designer needs to allow for.

Residential sprinklers are a type of fast response sprinkler only suitable for residential applications (not suitable for office, retail, industrial etc)
