I don't know what your AHJ is going to ask for James, however you might
find some guidance in 11.2.1(1) which covers adjacent hazards or design
methods, and requires the more demanding design to extend 15'-0" beyond
if there's no barrier separating them. Sub items (2) and (3) might be
helpful as well. I seem to remember similar language in 12.3 (1)-(2)
and (3) also.

We are doing an addition to an existing warehouse, the existing warehouse is
protected with ESFR K14 uprights, since the building was constructed the AHJ
has dropped the water pressures in the area by 10 psi.
Due to the pressure drop I cannot use the K14 heads for the addition, can
you mix ESFR sprinkler heads in the same warehouse area, I would need K17
heads for the addition, The addition would be open to the existing warehouse
space. Or do I need to change all the heads in the existing warehouse to
match?
Thank you
