allowed to invoke the “Equivalency” section… i.e. “nothing in this standard is

If I’m understanding these sections correctly, the occupancy above only really
makes a difference for porte-cocheres (9.2.3.2.1).
Otherwise, I think the need for sprinkler protection or not is determined by
construction type (combustible vs non-combustible), presence/storage of
combustibles,
But, (and I’m deliberately being the devil’s advocate here), which is worse:
1. 10 individual valves controlling small areas, any one of which could be
closed when it shouldn’t be?
2. 1 valve controlling the entire area, but which has to be shut each time

Negative. It can still be connected to the fire pump and be a manual wet
standpipe. It only becomes an automatic standpipe if/when the fire pump and
water supply is sufficient for the standpipe to operate properly without the
fire department providing flow/pressure through the FDC.

connections. It's in the code:

Actually, now that I read that, it just says that you aren't required to use

What I think you should do is adjust/select the PRV to provide a maximum static
outlet pressure of 175-psi based on whatever the maximum static inlet pressure

This is correct. Setting should be based on maximum static condition.
