My name wasn't listed so I am not sure I am able to respond (actually I was out of office on Fri).
In the 2002 edition, 8.3.2.1 states ordinary temp sprinklers are to be used throughout, UNLESS 8.3.2.2, 8.3.2.3, 8.3.2.4 OR 8.3.2.5 are met. So you are both right, 8.3.2.2 (the use of Table 6.2.5.1) can be used or 8.3.2.3 (the use of intermediate or high temp sprinklers in OH and EH) can be used. What he cannot do, is tell you to meet 8.3.2.2. Show him the OR word in 8.3.2.1.

You might want to point out that the intent of any TC can generally be found in the latest edition of a standard. When you say furniture retail, is this going to be a showroom only, with the sales floor done up as "rooms" for display only? Or will there be an area for storage as well, and what fire load overall do you anticipate? Seems to me that even a moderate load of furniture can still generate a pretty high release of energy and the 286 sprinklers (as Ron mentioned, I think) may well respond more symettrically. What is the height of the deck above and what's it framed with?

I believe 8.3.2.3 does explicitly allow this. The inspector has a different opinion. My position is 8.3.2.3 doesn't leave room for opinions, and wasn't intended to!
