The detection network in a mechanically actuated system uses a continuous cable run with detectors holding fusible links, specifically listed and rated for use with the Amerex KP system.
The PRM uses a linear pneumatic detection system consisting of tubing and end of line fitting. The tubing is pressurized through a small accumulator inside the enclosure, and is specifically listed and rated.
The manual pull stations are a dual action type. Both a ring pin and a lever must be pulled in order to discharge the system.
The wet chemical agent is a potassium acetate based solution that suppresses grease fire through saponification and cooling. The agent has a pH of less than 9 and does not harm stainless steel surfaces.
The agent cylinders are mild seel, tested to 480 PSI, they are available in capacities of 2.75, 3.75, 4.75, and 6 gallons, they are fully factory charged with Amerex KP liquid agent and pressurized to 240 PSI.
Nozzles and Suppression:
The discharge nozzles are appliance specific and made of chrome plated brass. They consist of a body with tip, strainer, tip, retaining nut, and blow off cap.
General System Specifications:
The KP system is pre-engineered and shall be designed, installed, and maintained according to NFPA 96 and NFPA 17A - Standard for Wet Chemical Extinguishing Systems.Amerex
The MRM is spring loaded and has electrical, mechanical, or pneumatic outputs. It is capable of actuating one to ten agent cylinders using a nitrogen cartridge. It is operated either automatically by the detection network or manually using a remote manual pull station.
The actuation cylinder or nitrogen cartridge is filled with 10 cu. in of nitrogen and has an integral pressure gauge which allows easy field verification of pressure.
