Ryan J,
I will inquire further when the opportunity presents itself (at my next inspection)

as i presently know diddlysquat about sprinkler systems perhaps you could help me review the general jist involved, as i suspect the state here has adopted (with a few minor addendums) the national standard

if it helps, we are on the '99 building code, the states is here (pdf) note page #30 , specifically other codes mentioned (as well as the rebate)

The USFA also touches on this , note the 3 stories or lower exemption...

thanx
