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 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 / � �., . R F DIRECTLY IN THE PATH OF GAS APPLIANCE ' ° ^�, EXHAUST FLUE GASES. DOING SO COULD v ''" ° r RESULT IN UNNECESSARY DISCHARGE OF THE SYSTEM. h� 4 n S 4 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 1 conduit offset (must be located at mechanical release module when chosen). _ ATTACH DETECTION NETWORK TO ANY ONE OF THREE SIDES.

October 2003 Section 3 Design Page 3 — 26 Amerex KP Wet Chemical System (EX 4658) • MECHANICAL GAS VALVE APPLICATIONS 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 1 l 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 , MOSFE, a. I NO 4H0 in this manual supplied by other manufacturers. See Section 3 "System Components" for all mechanical gas valves that Li are suitable for use with the Amerex Restaurant Fire Suppression ' System. The use of any other mechanical gas valves will avoid the UL NEI listing for the system installation. All of the listed valves have female NPT I threads. The location of the gas valve should be accessible and approved I — 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 1 pulley tee per network (counts as one corner pulley for each mechanical gas valve) Maximum of 1 conduit offset per network (must be located at pneumatic release module and before tee pulley when chose) DENOTES "SINGLE PATH" FOR ' - --� I CABLE LENGTH & PULLEY - I 1 I �" I QUANTITY CALCULATION. , I I i I _ l / l i')t — In �.. 1 - I mo -I F E 1 y .

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. • • P/N Size • Manufacturer C — r I 12870 3/e 12871 1" 12872 1W • 12873 1W Asco • 12874 2" 12875 • 2 12876 331 • ELECTRIC GAS VALVE OPERATION !; Power to the electric gas valve is run through the normally closed contact on a microswitch located in the pneumatic release module (PRM) or mechanical release module (MRM) to the manual reset relay and from the manual reset relay to the 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.

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 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 / EXHAUST FLUE GASES. DOING SO COULD �° P 4 4 'E9 RESULT IN UNNECESSARY DISCHARGE OF THE SYSTEM. / M 4 qS V4 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 1 conduit offset (must be located at mechanical release module when chosen).

October 2003 Section 3 Design Page 3 — 26 Amerex KP Wet Chemical System (EX 4658) MECHANICAL GAS VALVE APPLICATIONS 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 1 I 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 Or= _— but must be ordered separately for use with gas valves listed in this manual supplied by other manufacturers. "° " "° • U 11 See Section 3 "System Components" for all mechanical gas valves that L--1 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. • 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 1 pulley tee per network (counts as one corner pulley for each mechanical gas valve) Maximum of 1 conduit offset per network (must be located at pneumatic release module and before tee pulley when chose) DENOTES "SINGLE PATH" FOR U CABLE LENGTH & PULLEY r — 1 1 F _ _ QUANTITY CALCULATION. `� I I l i FI f - Tr - L ice' i _ 3 -1 I I _ r_ I I t PULLEY I I CONDUIT OFFSET TEE (OPTIONAL) y n - �[ DUAL GAS SINGLE GAS _ I.

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. • P/N Size Manufacturer • 12870 3 /4" . 12871 1 " 12872 1'/4" 12873 1W Asco • 12874 2" 12875 2 1 /2" 12876 3" • • • ELECTRIC GAS VALVE OPERATION Power to the electric gas valve is run through the normally closed contact on a microswitch located in the pneumatic release module (PRM) or mechanical release module (MRM) to the manual reset relay and from the manual reset relay to the 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.
