Amerex KP Systems are a pre-engineered type as defined in NFPA hA - Standard for Wet Chemical Extinguishing Systems. It is manufactured by the Amerex Corporation, Trussville, Alabama. It is essential that all installations of the Amerex KP Series Systems be performed in compliance with this manual. Those individuals responsible for the design, installation, operation and maintenance of the Amerex KP Restaurant Fire Suppression System must be trained by Amerex and hold a current Amerex KP Certificate. All piping limitations, nozzle coverages, detector placements, etc. have been proven and established through exhaustive testing by Underwriters Laboratories, Inc. Use of components other than those referenced in this manual, or installations exceeding limitations stated in this manual will void all of the Amerex KP Series System listings. LISTINGS: The Amerex KP Series is a listed pre-engineered restaurant fire suppression system. The KP system is listed with Underwriters Laboratories, Inc. - USA per UL 300 fire test specification;' Underwriters Laboratories of Canada, Inc. per ULC/ORD 1254.6 - 1995 and Loss Prevention Certification Board - UK per LPS 1223 rev. B. Testing required for listings under these standards involve live fire tests under specific conditions involving commercial kitchen hoods, ducts and appliances. Each test fire is allowed to reach its maximum intensity before agent is discharged. Each test was repeated using both maximum and minimum piping, variations in agent storage cylinder pressure to simulate maximum and minimum temperature ratings. Duct fire tests were extinguished with fans off and fans on; dampers open and closed. Splash tests for various appliances were conducted to assure that discharge of the agent would not cause excessive splashing of hot grease to provide greater employee safety during commercial cooking operations. UL Standard 300 introduces a series of tests by specifically addressing the use of high efficiency fryers, ranges, woks and the unique fire extinguishing challenges that these appliances present. DESIGN: The Amerex KP Series Pre-Engineered System consists of mechanical and electrical components to be installed by an Authorized Factory Trained and Certified Amerex KP Systems distributor. The system is composed of an agent cylinder/discharge valve charged with Amerex KP Liquid Agent and a Mechanical Release Module (MRM) or Pneumatic Release Module (PRM). The quantity of detectors, fusible links, nozzles, corner pulleys, pulley tees and manual pull stations will vary depending on kitchen design. The system operates either automatically if actuated by a detector or manually if actuated by a manual pull station. Upon system operation, energy sources for the cooking appliances are required to be shut off immediately. Electrical shutdown devices or suitable gas valves are referenced in this manual. Other equipment such as audible/visual signaling devices can be added where required. The Amerex KP System suppresses fire in commercial cooking equipment by spraying KP liquid agent in a predetermined manner onto cooking appliances and into exhaust ducts, filters and plenum areas. The primary means of fire suppression Is either by saponification of surface grease or by cooling the surface of oils and hot metal surfaces with fine droplets of agent, reducing the temperature of the oil and appliance below the auto-ignition point. Upon system discharge, the exhaust fans should be left on to aid in dispersal of the liquid suppressant that results in cooling the plenum and duct. Any integral make-up or supply air must be automatically shut off along with all cooking appliances. Some local Authorities Having Jurisdiction may require exhaust fans to be shut down by the fire suppression system. Check local fire codes and requirements in the specific area that the system is being installed. The Amerex KP System agent storage cylinders and cartridge shall not be installed in environments below 32° F or above 120° F (0° C to 49° C). CYLINDER MOUNTING BRACKET (P/N 16085) The munting bracket is used to secure the afreflt cylinder assembIto the mounting surface and J.o connect the discharge Ie to the distribution pipijp network.

AGENT CYLINDER/ASSEMBLY-KP600 (PIN 15196) 18 FLOW POINTS 011 Amerex KP600 - 6.14 Gallon Capacity - Agent Cylinder Assembly is shipped factory filled with Amerex KP Liquid Agent. It is pressurized with dry Nitrogen to a pressure of 240 psi (1655 kPa) at 70°F (200C). The nitrogen charge is the expellant gas which discharges the KP agent through the distribution network. Cylinders are shipped from the factory with a shipping plate installed on the top of the valve to prevent accidental discharge and an anti-recoil -plate on the valve outlet to redirect chemical flow should an accidental discharge occur. BOTH OF THESE PLATES MUST BE REMOVED AT INSTALLATION. Agent cylinders are DOT 4BW240, tested to 480 psi (3309 kPa) and require a hydrostatic test every twelve (12) years. The operating temperature of this and other listed components is 32°F to 120°F (0°C to 49°C ). The cylinder is fitted with an attachment bracket welded to the cylinder for ease of installation. The machined, forged brass discharge valve is actuated via a pneumatic actuator. The mechanical release module supplies the N2 required for actuation of one (1) to six (6) KP600 agent cylinder assemblies.

SINGLE SYSTEM INSTALLING THE DISTRIBUTION PIPING NETWORK: General For distribution piping network limitations please refer to the design section. ONLY SCHEDULE 40, BLACK, CHROME PLATED OR STAINLESS STEEL PIPE CAN BE USED FOR THE DISTRIBUTION NETWORK. GALVANIZED PIPE IS NOT ALLOWED. ALL PIPE MUST BE REAMED AND BLOWN CLEAR. DIRT AND/OR CUTTING OIL MUST BE REMOVED FROM THE INSIDE OF ALL PIPE AND FITTINGS BEFORE ASSEMBLY. All piping must be securely bracketed to a rigid surface using appropriate hangers and/or clamps. All distribution network pipe and fittings are to be assembled tight (3 turns past hand tight recommended). UNLESS SPECIFICALLY REQUIRED BY THE LOCAL AUTHORITY HAVING JURISDICTION, THE USE OF TEFLON TAPE IS PROHIBITED. JOINT SEALANT OR PIPE COMPOUND MAY NOT BE USED UNDER ANY CIRCUMSTANCES. The Amerex KP Restaurant Fire Suppression System does not require balanced piping. All distribution network piping shall be run in as direct a manner as possible throughout the hazard. The distribution network piping, once installed, shall be compared with the design drawing or sketch, any changes or deviations shall be noted for use in preparing an "as-built" drawing or sketch for the permanent job file. Piping installation shall start at the cylinder bracket and continue through the hazard with tees installed at the beginning of each branch line location. Branch lines shall then be installed taking care to assure that each nozzle is located properly and that no design limitations have been exceeded. NOZZLE LOCATION AND ORIENTATION ARE CRITICAL TO ACHIEVING PROPER SYSTEM PERFORMANCE. TO INSTALL HIGH TEMPERATURE BLOW OFF CAPS: Standard Nozzle: Remove standard blow off cap - thread the loop of the high temp. cap onto the base of the male threads on the nozzle. Install 0-ring on nozzle tip, place cap on nozzle tip. Swivel Adapter: Remove standard blow off cap - thread the loop of the high temp. cap onto the supply pipe before installing the nozzle body. Install 0-ring on nozzle tip, place the cap on nozzle tip. DETECTION NETWORK LIMITATIONS: MRM Optimum fire suppression system performance relies on proper detection network design. This section discusses the type of detectors used, their selection, placement and design limitations. The Amerex KID Restaurant Fire Suppression System MRM uses a continuous cable, corner pulleys, detector bracket, detector linkage, fusible links, conduit offset, terminal link connector and a temperature-measuring device. The quantity of detectors to be used in a system will depend on the number of ducts, number of appliances and the location of the appliances under the hood. DETERMINING DETECTOR LOCATION AND NUMBER OF DETECTORS In order to detect a fire in the duct, a detector is required to be placed in the center of the duct, either at the duct opening or up to 12 inches into the duct. If it is mounted into the duct, the bracket cannot shield the fusible link from the hot vapors moving through the duct. Every appliance under the hood that is being protected by the suppression system must have a detector placed over it and positioned within the path of exhaust vapors. WARNING: DO NOT LOCATE DETECTORS DIRECTLY IN THE PATH OF GAS APPLIANCE p EXHAUST FLUE GASES. DOING SO COULD J RESULT IN UNNECESSARY DISCHARGE OF THE SYSTEM. GENERAL LIMITATIONS OF DETECTION NETWORK: Maximum of 24 corner pulleys. (either style) Maximum of 20 detectors (any combination of temperature settings). Maximum of 120 feet of cable on the detection network. No pulley tees are allowed. Remote manual pulls are not allowed on the detection network.

Upon system discharge current to the solenoid is interrupted by a microswitch in the MRM or PRM causing the valve to shut. A loss of electrical power will also cause an electrical gas valve to close. A manual reset relay must be used with electric gas valves. UL listed sizes are %", 1", 1W, 1/2", 2", 2W, 3". MANUAL RESET RELAY (PIN 12526) Anytime an electrical gas valve is connected to an Amerex KP Restaurant System, a manual r e s e t r e l a y m u s t be used. After an electrical gas valve has closed (either because of system discharge or because of power failure), the valve cannot be opened without manually pressing the reset button on the manual reset relay. This operation is to guard against a momentary loss of power closing the valve, extinguishing the pilot lights and allowing gas to escape when power is restored. The manual reset relay is UL listed and has a pilot lamp to indicate its status. DESCRIPTION: MANUAL RESET RELAY CONTACT CONFIGURATION: DOUBLE POLE, SINGLE THROW MINIMUM CONTACT RATING: MTR LOAD =8 AFL, 48 ALR, 120 VAC RES LOAD = BA, 120 VAC PILOT DUTY 120 VA, 120 VAC MECHANICAL RELEASE MODULE (MRM) (P/N 11977) The mechanical release module is used to actuate the agent cylinder/discharge valve either automatically or manually by puncturing a nitrogen cylinder. The pressure from the cylinder pneumatically opens the discharge valve(s). Automatic release of agent is accomplished when a fusible link detector separates under a fire condition and releases tension on the cable. This causes a spring-loaded plunger to perforate the cylinder seal and releases nitrogen through the. actuation hose/piping network to the discharge valve(s). Manual release of agent is accomplished by pulling on a manual pull station which is connected to the mechanical release module by a cable. The mechanical release module is equipped with one microswitch (P/N 12524) for electrical signaling, power shutdown and other auxiliary functions. An additional three microswitches may be added. Operation of one or two mechanical gas valves may be accomplished by adding a piston plug/gas trip assembly (P/N 12740). The cable for the gas valves, manual pull stations and detection network may be attached to the MRM from any of three sides (top, bottom and right). .11 I AMEREX PART NO. 12524 AMEREX PART NO. 12740 SINGLE BURNER RANGE PROTECTION ONE - V2 FLOW POINT NOZZLE (PIN 11984) The Amerex half (Y2) flow point nozzle (P/N 11984) will protect a singh burner with a surface area of 18" x 18" (46 x 46 cm).
