Total appliance protection therefore, requires the use of a total of four Amerex nozzles (P/N 11982). This unique appliance is actually two chain broilers put together to accommodate the cooking of two different products at the same time. This appliance can be fitted with two catalysts (18" x 24" overall) one for each cooking side. The protection of the appliance is accomplished by using two nozzles PIN 11982 positioned two inches outside of the catalyst perimeter aimed at the center point of the catalyst. The nozzles are to be located on opposite ends of the catalyst, 1800 apart and are to be 13" to 36" above the top surface of the catalyst. This configuration is repeated for both cooking sides of the appliance. If no catalyst is used the same protection is required for the unit. Note: Maximum & minimum heights must be measured from the tip of nozzle to the top surface of the catalyst or appliance (if no catalyst is used). 71 -- TOP VIEW -- -- NOZZLE LOCATED 2" BEHIND THE EDGE OF THE CATALYST AIMED TO THE CENTER OF THE CATALYST - 18' x 24 Ak A 12"-36NOZZLE HEIGHT ABOVE CATALYST \\\ •// \\ 1,1 FRONT VIEW I14IL,L tlu4o CHAIN BROILER Nozzle PIN Flow £ rOifli.S .

October 2003 Section 3 Design Page 3 - 23 Amerex KP Wet Chemical System (EX 4658) 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 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. Maximum of I conduit offset (must be located at mechanical release module when chosen).

Temperatures found at each detector should be recorded and placed with other documentation in the job file for future reference.

The PRM has provisions for a single, continuous section of detection tubing. No splicing or "tee's" are allowed. There shall be only two tubing terminations - one at the accumulator cylinder inside the PRM and the other at the opposite end of the tubing, with the use of an End of Line fitting (P/N 16506).

SEGMENT REQUIRED O N EACH SIDE FROM END OF HOOD OF THE DUCT TERMINAL CONNECTOR & EMT FITTING HANDY CONDUIT BOX 21/8"X4" HOOD The Linear Fusible Link Detection System provides complete hood fire detection by placing thermal links at maximum 24" intervals the entire length of the hood. Installing the links in this manner allows the appliances to be placed anywhere under the hood without having to locate links directly over each appliance. A unique system of cable segments, pre-fabricated, has been developed to make the installation of this system simple and easy. It eliminates the use of conduit, link holders and mounting brackets under the hood in the plenum area. The limitations of the Linear Fusible Link Detection System are as follows: Maximum of 20 detection links and (19) Link to Link Cable Segments. Maximum of 30 feet of cable used in the Link to MRM Cable Segment. Maximum of 20 corner pulleys. (either style) Maximum unsupported detection cable length is 8'-0". Refer to Fusible Link Selection section, page 3-24 of this manual for proper selection process. The higher setting links are to be used when higher temperatures are encountered with appliances such as char-broilers. The Linear Fusible Link Detection System is for use in single hood applications, or where multiple hoods are connected "end to end" only. It can not be used for "back to back" hood arrangements or multiple hoods that are mounted in separate locations and are part of a single KP Fire Suppression System. October 2003 Section 3 Design Page 3 - 25 Amerex KP Wet Chemical System (EX 4658) MANUAL PULL STATION NETWORK LIMITATIONS Every Amerex KP Restaurant Fire Suppression System installation must have at least one manual pull station. The manual pull station network consists of cable, corner pulleys, pulley tee, manual pull station(s) and optional conduit offset. GENERAL LIMITATIONS OF MANUAL PULL STATION NETWORK Maximum of 20 corner pulleys per manual pull station Maximum of 130 feet of cable per manual pull station Maximum of I pulley tee per network (counts as one corner pulley for each manual pull station) Maximum of I conduit offset per network (must be attached to the MRM and before tee pulley when chosen) NOTE: Manual pull stations should be installed no higher than 48 inches from the floor and must be along a path of egress.

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 -EREX PART NO. 12740 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 valveshould 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. MECHANICAL GAS VALVE ACTUATION NETWORK LIMITATIONS The mechanical gas valve actuation network consists of cable, corner pulleys, pulley tee, gas valve and conduit offset. GENERAL LIMITATIONS OF MECHANICAL VALVE NETWORK Maximum of 20 corner pulleys per mechanical gas valve of any listed type in KP Manual Maximum of 130 feet (39.6m) of cable per mechanical gas valve of any listed type in KP Manual Maximum of I pulley tee per network (counts as one corner pulley for each mechanical gas valve) Maximum of I conduit offset per network (must be located at pneumatic release module and before tee pulley when chose) October 2003 Section 3 Design Page 3— 27 Amerex KP Wet Chemical System (EX 4658) ELECTRICAL GAS VALVE APPLICATIONS 110 VAC electrical gas valves may be used in place of the mechanical gas valves. The electric shut off valve used with the Amerex KP Restaurant Fire Suppression System must be UL listed for use with natural gas or propane, be held open by energizing an electric solenoid and be wired through a microswitch and manual release relay. A qualified electrician must do any field wiring and connections involving the shut down of electrical cooking equipment or an electric gas valve.

In a normal (non fire) condition, current is allowed to flow to the solenoid on the electric gas valve, holding the valve open. In a fire condition, when the release module actuates the suppression system, the microswitch contacts will transfer, opening the normally closed contacts in the manual reset relay, interrupting current to the gas valve and cause it to close. Resetting the MRM or PRM and transferring the contacts back to a normal (normally closed) position will not cause the electrical gas valve to open. The manual reset relay must reset before current will flow to the valve and cause it to open. A loss in electrical power, even temporary or momentary, will require someone to manually reset the relay before the electrical gas valve will open again.
