Travis,

Like Bruce, I may be a few years out of date also but I've never seen one
of these connected to a sprinkler system. They are for a special hazard and
so independent of the life safety and building protection definition for a
sprinkler system. These are designed to smother the fire with the
saponifying agent and then use the water to cool down the appliances to
avoid reflash. Way back in the nineties, this system was a way that Ansul
came up with to meet the new requirements of UL 300. requirements that
commercial cooking operations had to comply with even in unsprinklered
buildings (think stand-alone McDonald's, Red Robins, etc, under 5000 or
6000 sqft that weren't required to be sprinklered then). Note that NFPA 13
isn't even referenced as an applicable code/standard.

CODES AND STANDARDS
The PIRANHA hybrid wet agent system and its components meet the following
codes, standards and recommended practices:

1. Underwriters Laboratories, Inc. (UL): Standard 300 – Fire Testing of
Fire Extinguishing Systems for Protection of Restaurant Cooking Areas.

2. Underwriters Laboratories, Inc. (UL): Standard 2092 – Pre-Engineered Wet
Chemical Extinguishing Units.

3. Underwriters Laboratory of Canada (ULC): Standard ORD-C1254.6 –
Pre-Engineered Wet Chemical Extinguishing System Units.

4. National Fire Protection Association (NFPA): Standard 17A – Wet Chemical
Extinguishing Systems.

5. National Fire Protection Association (NFPA): Standard 96 – Ventilation
Control and Fire Protection of Commercial Cooking Operations.

6. American Society of Sanitary Engineers (ASSE): Standard 1001 – Cross
Connection Protection Devices: Guidelines for Selection of the Proper Type
of Backflow Preventor – Piped Applied Atmospheric Vacuum Breakers.

7. International Association of Plumbing and Mechanical Officials (IAPMO):
Installation, Material and Property Standard PS 108-98 – Grease Fire
Suppression Systems.
