The Amerex KP automatic restaurant fire suppression system protects the hood, duct and appliances. In either automatic or manual actuation the system works in this manner:
1. When a fire starts, the detection network, consisting of fusible links or pneumatic tubing, will automatically detect the fire or the manual pull station can be used, releasing a low pH agent throughout the hood, duct and onto the appliances.
2. Either method of actuation will interrupt gas or electrical power to the appliances preceding system discharge.
3. The Amerex KP agent quickly suppresses the fire and cools the fuel while securing the vapors with a smothering foam reaction.
The combination of the Amerex KP system and an Amerex Model B260 or B262 Wet Chemical extinguisher provides restaurants with a “ONE-TWO” attack against the threat of business loss due to cooking operation fires. CEILING TILE CORNER PULLEY AMEREX KP SYSTEM AGENT CYLINDER

RESTAURANT KITCHEN GAS APPLIANCES PROTECTED BY: AMEREX KP RESTAURANT FIRE SUPPRESSION SYSTEM SPECIFICATIONS
GENERAL: The Amerex KP Restaurant System is a pre-engineered, wet chemical, stored-pressure type with a fixed nozzle agent distribution network. The system is listed by Underwriter’s Laboratories, Inc., ULC and tested to U.L. Standard 300. The system shall be designed, installed and maintained in accordance with: Amerex Part No. 12385 “Design, Installation and Maintenance Manual”, N.F.P.A. 96, N.F.P.A. 17A, local codes and ordinances by an Authorized Amerex KP Systems Distributor using factory trained personnel.
ACTUATION CYLINDER: The actuation cylinder is filled with 10 cu. in. of nitrogen and has an integral pressure gauge which allows easy field verification of pressure. This cylinder is capable of being refilled in the field by an Authorized Amerex KP Systems Distributor.
AGENT: The system agent is Amerex KP liquid fire suppressant, a potassium acetate based solution that suppresses cooking grease fires both through saponification and cooling. The agent has a pH of 9 or less and does not harm stainless steel surfaces.
AGENT CYLINDER BRACKET: The agent cylinder bracket is steel, painted red, with a factory supplied discharge hose, pipe outlet or discharge fitting.
AGENT CYLINDERS: (2.75, 3.75, 4.75, AND 6 GALLONS) The agent cylinders are mild steel DOT 4BW 240 specification cylinders, tested to 480 PSI (3309 kPa). The agent cylinder/discharge valve assembly is fully factory charged with Amerex KP liquid agent and pressurized to 240 PSI (1655 kPa). MECHANICAL RELEASE MODULE (MRM): The mechanical release module is the spring-loaded type using a mechanical input and electrical, mechanical or pneumatic outputs. It is capable of actuating from one to ten agent cylinder/ valve assemblies using one nitrogen cylinder and is operated either automatically by the detection network or manually by a remote manual pull station. The MRM enclosure, available in either stainless steel or red painted steel has a system status indicator and a window to observe the nitrogen cylinder pressure. The enclosure has provisions for applying tamper seals after final testing or periodic maintenance. The MRM enclosure has knockouts on three sides (top, bottom & right) to accept conduit. The MRM has two SPDT micro switches pre-installed. MRM DETECTION: The detection network uses a continuous cable run with detectors specifically listed for use with the Amerex KP system. MRM LINEAR FUSIBLE LINK DETECTION: The link to link system consists of four major components conduit connector, cable segment beginning and end, conduit box, and link to link cable segment. The link to link cable segment ensures that the links are equally spaced at 24” center to center and yields continuous linear detection from end to end of the hood. PNEUMATIC RELEASE MODULE (PRM): The PRM offers superior detection by using a linear pneumatic detection system. The PRM detection system consists of the PRM, tubing and end of line fitting. The tubing is pressurized through a small “accumulator” inside the enclosure, routed throughout the hazard area. When exposed to a fire condition, the tubing ruptures, relieving all of the pressure in the tubing and accumulator thus firing the system using a nitrogen cylinder. The PRM comes complete with enclosure, accumulator, end of line fitting, connector for mechanical manual pull, two
SPDT microswitches, and “knock-outs”. It is capable of actuating up to 10 cylinders and releasing 2 gas valves. Available in stainless or red enclosure.
STAINLESS STEEL ENCLOSURE (Optional): An enclosure housing an MRM and one agent cylinder is available. The pressure gauges for the nitrogen cylinder and the agent cylinder are visible without removing the front cover of the cabinet. Also available in a stainless steel single agent cylinder enclosure.
DISCHARGE NOZZLES:
Discharge nozzles are made of chrome-plated brass, and shall consist of a one piece tip/body, strainer and blow off cap.
MANUAL PULL STATIONS: The manual pull stations are a “dual action” type. Both a ring pin and lever must be pulled in order to discharge the system manually. MECHANICAL GAS VALVES - ¾ TO 3” INCH SIZES: A brass body mechanical gas valve, specifically listed by U.L. for use with the Amerex KP system, shall be installed for automatic shut off of gas whenever gas appliances are used. The valve has a “pull to close” design requiring a pull force to trip a latch which holds the valve in the open position. The cover of the gas valve has a visual indicator showing the valve’s position. Existing mechanical valves, if operating, may be used according to the listed manual. ELECTRICAL GAS VALVE ¾ TO 3” INCH SIZES: If an electrically operated gas valve is required, it must be U.L. Listed for use with the Amerex KP system and operate by using a micro switch and a U.L. listed manual reset relay. Upon system actuation, current to the solenoid is interrupted by a micro-switch causing the gas valve to close. A manual reset relay must be used with electric gas valves. ELECTRIC MICRO-SWITCH: U.L. listed electric micro switches are provided to accomplish system output functions. The switches are “stackable” inside the MRM / PRM without requiring extra mounting hardware. From 1 to 4 sets of dry form “C” contacts are available. Two factory installed micro-switches are provided.

Amerex recognized and addressed the unique hazards of modern restaurant cooking by creating the Model B260 and B262 Class “K” Wet Chemical “Kitchen Use” fire extinguisher. This extinguisher along with the research and tests to develop it has changed the way that NFPA regards cooking grease fires. After July 1, 1998, all new installations of fire extinguishers protecting cooking hazards require a Class “K” extinguisher. This class recognizes the unique nature of cooking grease which requires not only extinguishment but the cooling effect which is best obtained with WET CHEMICAL extinguishers. When the KP System is used in combination with the Amerex Model B260 or B262 you have the perfect two step attack for kitchen fire suppression!
NFPA-10 (5.7.1) “Class K fire extinguishers shall be provided for hazards where there is a potential for fires involving combustible cooking media (vegetable or animal oils and fats).”
THE ORIGINAL CLASS K EXTINGUISHER! ISO 9001:2001 ISO 14001:2004 CERTIFIED
