NFPA 1 provides information regarding reduction of fire flows in
those jurisdictions that have adopted this code. Section 18.4.5.2 &
18.4.5.2.1 allow a reduction of 75% for an approved automatic sprinkler
system but not less than 1000 gpm and a structure utilizing Quick Response
sprinklers can be reduced to not less than 600 gpm.

Subject: Re: Water Supply Evaluation
I would probably make sense to have the Architect or his Engineer make the
call. There is an allowance in 1142 for the AHJ to decrease the required
volume for a sprinklered building. Is he/she taking this into consideration?
