It's designed to be tied into either the plumbing system (probably assuming no sprinkler system present) or into the supervised sprinkler system.
The one issue I see with tying it into the sprinkler system is that it is programmed to do a daily wash down. If this were tied into the sprinkler system you'd get a flow alarm every time it operated. Craig L.

We always push back and have the plumbing contractor supply to it. Do so by saying if it connects to the fire sprinkler system there needs to be a valve and that valves needs to be monitored and then it snowballs into its just easier for plumbing to add it as if was a ice machine etc. IMHO From: Sprinklerforum [mailto:[email protected]] On Behalf Of Eric V.

Section 7.7 addresses connections for heating and cooling but clearly state there can be no water discharge from those auxiliary systems. Eric V.

It uses water combined with a surfactant to make it work. Apparently it is ETL listed to UL 300 standards and meets criteria of NFPA 17A (wet chemical extinguishing systems) and NFPA 96. Looks like it can be tied into plumbing systems or building sprinkler system. So what NFPA language would prevent this from being connected to the sprinkler system? Craig L.

Tysinger Sent: Thursday, April 20, 2017 2:06 PM To: [email protected]<mailto:[email protected]> Subject: Hood System - Question [EXTERNAL] Good afternoon all, Apparently, there is a standalone approved/listed type of hood suppression system for kitchens that uses water as the extinguishing agent. Within their data sheet it states that it requires a supervised water source "or" that it may be tied into the fire sprinkler system. It has a minimum required starting water pressure of 30psi and "IF" it is supplied/tied into the sprinkler system then it would most definitely have to be accounted for in the hydraulics. But, it is obviously not a part of the fire sprinkler system or NFPA 13. My first thought is that regardless of their data sheet, it shouldn't be allowed per NFPA 13. Am I thinking correctly? Wouldn't it be considered a non-system component and not allowed? [USBR Best of USA 2016_rev2] Eric V.
