Thanks Yuriy. I actually looked up the code and it says that only systems installed before 1991 would need monitoring and just for Groups H and I. Because it differentiates between Automatic Fire Extinguishing Systems and Automatic Sprinkler Systems, it makes me think that the former is for non-water-based systems...
F-903.6.7 Monitoring of existing fire extinguishing systems. Automatic fire extinguishing systems installed on or after March 1, 1991 and automatic sprinkler systems installed in Gr oup H and I occupancies and high- rise buildings prior to March 1, 1991, shall be monitored in accordance with Sections F-903.4 and F-904.3.5 as applicable. Where systems are monitored on site at a constantly attended location, approval of the fire code official is not required.
I also found out that the triplex most likely doesn't actually require a sprinkler system in the first place so I've been trying to see if that's correct, and if so it wouldn't need the system or monitoring. Just trying to sort this all out. Anyone have insight, please chime in.
