AGENT CYLINDER/ASSEMBLY-KP600 (P/N 15196) 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 (20°C). 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. KP600 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.

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 two microswitch (P/N 12524) for electrical signaling, power shutdown and other auxiliary functions. An additional two 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 riQht).

The detector bracket, detector linkage and the fusible link (ordered separately). The bracket seJVes as support for the linkage and is attached to a rigid surface. The linkage supports the fusible link and a continuous cable under tension. At a predetermined temperature the fusible link will separate, relieving tension on the cable and actuating the system. Fusible link not included with detector This manual will refer to series and terminal detectors. There is no difference in part numbers or dimensions between series and terminal detectors. A terminal detector is the last or only detector in the network and the cable must be "terminated" there. A series detector is any detector located between the terminal detector and the mechanical release modufe in the detection network. TEST LINKS (PIN 12891) Test links are available for conducting functional tests of the detection system. This device fits the detector in the same manner as the fusible link, is normally placed on the terminal detector and can be cut, simulating a fusible link separating under fire conditions. CORNER PULLEY (P/N 12309) The Amerex KP Restaurant System uses a "high temperature" comer pulley to change direction of the cable by 90'. This corner pulley may be used in environments with temperatures up to 700'F (371 "C). Mounting holes are provided for anchoring the comer pulley where allowed by local codes. CORNER PULLEY (PIN 16444) The Amerex KP Restaurant System also uses a "high tempera1ure• compression comer pulley to change direction of the cable by 90'. (This compression corner pulley [Brooks Model CPS] allows complete assembly of conduit and corner pulleys prior to installing the cable ). PULLEY TEE (P/N 12506) A pulley tee is used to change the direction of two cables by 90'. This device can be used with mechanical gas valves and manual pull stations but not fusible link detectors. II cannot be used where temperatures exceed the range of 32' -120'F (0° -49'C). CABLE (PIN 12553) r 13164" dia.

October 2003 DETECTION NETWORK LIMITATIONS: MRM Section 3 Design Amerex KP Wet Chemical S stem Page 3 -23 EX4658 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 KP 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 within 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 EXHAUST FLUE GASES. DOING SO COULD 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.

' . October 2003 MECHANICAL GAS VALVE APPLICATIONS Section 3 Design Amerex KP Wei Chemical S stem Page 3 -26 EX 4658 The PRM or MRM closes the mechanical gas valve immediately upon system discharge. A pneumatic and mechanical action in the gas trip assembly pulls on a cable attached to the mechanical gas valve, unlatching. the valve and allowing an internal spring within the valve body to provide the closing force. Connection of the cable from the valve to the PRM or MRM under tension maintains the gas valve in an open position. MECHANICAL GAS VALVE A mechanical gas valve trip assembly must be used with any mechanical gas valve. The gas valve trip assembly (P/N 12740) is included with all Amerex manufactured gas valves but must be ordered separately for use with gas valves listed in this manual supplied by other manufacturers. See Section 3 "System Components" for all mechanical gas valves that are suitable for use with the Amerex Restaurant Fire Suppression System. The use of any other mechanical gas valves will avoid the UL listing for the system installation. All of the listed valves have female NPT threads. The location of the gas valve should be accessible and approved by the local Authority Having Jurisdiction. A contractor licensed and qualified for such work should perform installation of the mechanical gas valve into the gas line.
