You may also want to look into putting a combination of roof sprinklers and
in-rack sprinklers to accomplish this.
Are there smoke and heat vents in the building? If so and a roof height of 27'
or lower, you could do the special design of .60/2000 with standard heads.

You could use a non-ESFR sprinkler like the Tyco K17-231 standard response,
standard coverage sprinkler. It comes in both upright and pendent. Area density

The Appendix states every time you drain and refill the system you must release
the trapped air, so by definition a system has a control valve, Water flow
switch and a drain. thus each floor can be independently shut off and drained
