You can't exceed 40k sq ft of storage in one system. That gives you up
to 12k sq ft of Light/Ordinary hazard to go with your space. If the
office space is not designated yet, the AHJ may be going that it is all
storage today and he wants it protected for today.
However, I would try to argue a bit of common sense. What benefit will
the extra control valve give you? It is just another failure point in
the system. FM Global has pretty much gone away with system size
limitations as they are somewhat self limiting.

We have a multi-tenant warehouse building, 43,000 ft², it will be
divided into 3 tenant spaces of about 14,300 ft² each with loading
bays in the rear of the warehouse and allowance for 3,000 ft² of
office at the front of each tenant space. The warehouse space will be
designed for high pile storage utilizing ESFR sprinkler heads. As the
building will be shell coverage the AHJ is saying we require 2
sprinkler zones as we are over 40,000 ft²
We have allowed for 1 sprinkler zone for the building on the
assumption the rear of the warehouse is used for loading and unloading
with no high storage, there will be future office space up to 3,000
ft², this would allow a system up to 52,000 ft², and we would be
43,000 ft²
Any comments or direction that will allow our assumption
Thank you
