Another option is to use a Cease Fire Device. I know it’s not sprinkler work in 
particular but you can order and install them. They have a switch that will 
allow them to be monitored ir required. I have installed a few over the years.

NFPA 101 would probably be most applicable, in 2024 it’s 9.7, basically you can 
connect up to 6 heads to domestic calculated at 0.15 gpm/sq ft for a “hazardous 
area”, I would call that out as what you’re using for criteria.

Subject: [Sprinklerforum] FW: Calc's for (1) Head ??

GC asked us to add (1) head to a dentist office closet where they store the 
nitrous tanks. Not a big deal, done it before tapping off the domestic line. 
AHJ decided he wants calc’s to prove it will work. The existing building is not 
sprinkled.
