Did you provide a water curtain around the opening on the first floor as well?

If not, I would be protecting both levels the same. I just had one of these recently as well. I prefer to stay away from ESFR when there is a CMSA option just due to the extra installation rules for ESFR which seem too often be ignored.

It will not be enclosed or have solid shelves and the tires will be on-tread. They are designing the building so that the carousel will start on the 1st floor going through the 1st floor deck to the 2nd floor. IE: load tires from the 2nd floor and then remove them for use on the 1st floor. I plan on treating this as a fixed rack and using chapter 18, table 18.4(d) ESFR sprinkler protection for 25ft of storage with a 30ft roof utilizing k25.2 @ 15psi +250 hose at the roof top of the 2nd floor to 15ft beyond the tire carousel. We are providing a water curtain around the opening at the 1st floor deck. Question -Can I keep the OH2 (repair garage) density for the 1st floor sprinkler system in the area around the tire carousel?
