This regulated release assembly is used in single, double, and multiple-tank systems and must be mounted to a rigid surface. The release mecha- nism can be used to interconnect both the actuation and expel- lant gas lines as required per system design. The regulator is designed to allow a constant flow of gas into the tank at 110 psi (7.6 bar) when the system is actuated. The agent tank must be ordered separately. In single, double, and multiple-tank systems, the provided expellant gas hose connects the agent tank to the bottom outlet of the regulator. In double and multiple-tank system configura- tions, the back outlet of the regulator is used as an expellant gas feed for one additional tank-enclosure or tank-bracket hookup. The enclosure contains the required knockouts to facilitate this connection. If a pressure switch is to be attached to the regulator, additional fittings are required. The tank is mounted within the enclosure. The tank contains an adaptor/tube assembly with a burst disc union. The burst disc helps prevent siphoning of the agent up the pipe due to significant temperature fluctuations in the area where the tank is located. The tank is stainless steel and, under normal condi- tions, requires hydrostatic testing every twelve years. The detection and additional equipment required per system design are connected to the release mechanism. The enclosure contains knockouts to facilitate detection and additional hookups. The system can be actuated automatically or manually. Automatic actuation occurs when a fusible link within the detec- tion system separates in a fire condition. Manual actuation of the system occurs when personnel pull on the, remote manual pull station pull ring. REGULATED RELEASE ASSEMBLY (ELECTRICAL) The AUTOMAN Regulated Electrical Release Assembly (Part No. 429856) is identical to the mechanical version except it also contains a factory installed 120 VAC solenoid and electrical switch. The solenoid is used to provide electrical actuation of the release mechanism. The electric switch is used to protect the solenoid by opening the circuit to the solenoid once the system is fired. Additional electrical switches can be added as required for automatic equipment and gas shut-off accessories, as well as initiating audible and visual alarms.

(Fusible links are not included and must be ordered separately.) The bracket holds the entire assembly to the mounting surface. The linkage is used to support the fusible link. The fusible link is designed to separate at a specific temperature and release the wire rope, thereby actuating the regulated release mechanism. The scissor style detector allows the wire rope to be strung com- pletely through the detection system conduit and brackets first and the detector linkage assemblies are then clipped on later. The detector consists of two types of assemblies: The Terminal Detector (Part No. 435546) includes a test link and is placed last in a series of detectors. This detector is some- times referred to as the end-of-line detector and is thus named because it is at the point at which the wire rope "terminates," or is anchored at the detector bracket. Only one terminal detector is required per detection system. The Series Detector (Part No. 435547) is any detector located in-line between the regulated release assembly and the terminal detector. When using Part No. 435546 and 435547 detectors, a total of 15 detectors can be in one detection system: 14 series detectors (Part No. 435547) and 1 terminal detector (Part No. 435546).

IN-LINE BURST DISC ASSEMBLY (MANIFOLDED SYSTEMS ONLY) The in-line burst disc assembly is required to eliminate the siphoning of the agent up the pipe during extreme temperature variations. In addition to eliminating the siphoning effect, the common in-line burst disc assembly eliminates the possibility of one or more individual discs located in the tank adaptor from failing to burst. The assembly consists of a stainless steel body which houses the burst disc. When utilizing this assembly in a manifolded system, it is necessary to modify (remove) the burst disc located in all of the R-102 tank adaptors in the system. The in-line burst disc assembly is to be mounted as close to the tank outlet as possible. After system discharge, the assembly must be disassembled and a new burst disc installed.

R- 102 Restaurant Fire Suppression Manual SYSTEM DESIGN The ANSUL R-1 02 Restaurant Fire Suppression System may be used on a number of different types of restaurant cooking appli- ances and hood and duct configurations. The design information listed in this section deals with the limitations and parameters of this pre-engineered system. Those individuals responsible for the design of the R-102 system must be trained and hold a current ANSUL certificate in an R-102 training program. The R-102 and the PIRANHA systems use compatible agents and components, therefore, they may be used together for cooking appliance, hood, and duct protection. The primary AUTOMAN Release can be either an R-102 or a PIRANHA AUTOMAN Release and can actuate up to two additional R-1 02 or PIRANHA Regulated Actuators. In systems utilizing a 101 remote release, any combination of the maximum number of regulated actuators can be used. Both systems must actuate simultaneously. Each system must be designed and installed per its appropri- ate manual. Adjacent appliances requiring protection must be protected with the same type of system, either R-102 or PIRANHA, unless the center-to-center spacing between the adjacent R-102 and PIRANHA nozzles is no less than 36 in. (914 mm). When appliances are protected with R-102 nozzles, the hood and connecting duct above those appliances cannot be protected with PIRANHA nozzles. Mixing systems in a common plenum is not allowed. One of the key elements for restaurant fire protection is a correct system design. This section is divided into 10 sub-sections: Nozzle Placement Requirements, Tank Quantity Requirements, Actuation and Expellant Gas Line Requirements, Distribution Piping Requirements, Detection System Requirements, Manual Pull Station Requirements, Mechanical Gas Valve Requirements, Electrical Gas Valve Requirements, Electrical Switch Requirements, and Pressure Switch Requirements. Each of these sections must be completed before attempting any installation. System design sketches should be made of all aspects of design for reference during installation. NOZZLE PLACEMENT REQUIREMENTS This section gives guidelines for nozzle type, positioning, and quantity for duct, plenum, and individual appliance protection. This section must be completed before determining tank quan- tity and piping requirements. SECTION 4— SYSTEM DESIGN UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 4-1 GENERAL INFORMATION 1.

The maximum distance from the end of the hood to the first and last nozzle must be no more than 2 ft (0.6 m). After the first nozzle, any additional nozzles must be positioned at a maximum of 4 ft (1.2 m) apart down the entire length of the plenum. The plenum width must not exceed 4 ft (1.2 m). (The 1W nozzle can be used on single or V-bank filter arrangements.) See Figure 4-6. FIGURE 4-6 000197 When protecting plenums with the 1W nozzle, two options of coverage are available: Option 1: The 1W nozzle must be on the center line of the single or "V bank filter and positioned within 1-20 in.

(50-101 MM) R- 102 Restaurant Fire Suppression Manual For a plenum, either single or "V" bank, with a linear extension o. longer than 10 ft (3.0 m), each bank may be protected using one 1 nozzle every 10 ft (3.0 m) or less depending on the overall length of the plenum. See Figure 4-12. The nozzles may point in the opposite directions as long as the entire plenum area is protected, and the 10 ft (3.0 m) limitation is not exceeded. See Figure 4-13. The nozzle positioning shown in Figure 4-14 is not an acceptable method of protection because the plenum area directly under the tee is not within the discharge pattern of either nozzle.

Each design requires several factors: correct nozzle choice, correct nozzle height above hazard, correct nozzle location and correct aiming point. Fryer - Single Nozzle Protection 1. Design requirements for fryers are broken down into two types. FRYERS WITHOUT DRIPBOARDS If the fryer does not include a dripboard, measure the internal depth (horizontal dimension from front to back) and length of the frypot. FRYERS WITH DRIPBOARDS If the fryer includes any dripboard areas, measure both - the internal depth (horizontal dimension from front to back) and length of the frypot portion, and then measure the internal depth and length of the overall hazard area including any dripboard areas. 2. Using Table, 'Maximum Cooking Area Dimension - Single Nozzle Fryer Protection," determine which nozzle is needed to protect the fryer based on the maximum dimensions listed. If the fryer does not include a dripboard, use the maximum dimensions listed in the first column of the table to select the correct nozzle. If the fryer includes any dripboard areas, use both the maximum frypot dimensions in the first column of the table, and the maximum overall dimensions in the second column of the table to select the correct nozzle. None of the maximum dimensions in either column may be exceeded. - 3. If either the maximum frypot or the overall sizes are exceeded, an additional nozzle(s) will be required. Refer to the multiple nozzle requirements. Example: A flyer with a dripboard. The inside of the frypot without the dripboard measures 18 in. in depth x 18 in. in length (457 mm x 457 mm) and the inside of the overall area includ- ing the dripboard measures 18 in. in depth x 24 in. in length (457 mm x 610 mm). From the Table "Maximum Cooking Area Dimension - Single Nozzle Fryer Protection," either the 3N or the 290 nozzle should be selected to protect the fryer, depend- ing on the maximum nozzle height above the flyer and the positioning requirements allowed.

(520 mm). The 1W nozzle tip must be positioned at or below the obstruc- tion, if present. The protected area begins at the point straight down from the nozzle tip. The nozzle can be positioned above the edge of the hazard area to be protected. See Figure 4-51 and 4-52. Note: If the hazard area exceeds the single nozzle coverage listed above, additional nozzles will be required. The additional nozzle can be positioned in front at high proximity or at the side at low proximity. F 15-20 IN.

Chain broilers utilizing catalytic converters can be protected from overhead using model specific protec- tion identified in the "Specific Application by Model" section in System Design. Or, they can be protected with standard i1I nozzle horizontal chain broiler protection with the nozzles posi- tioned at either end of the chain broiler openings. Refer to the "Horizontal Chain Broiler Protection" section for specific design information. Horizontal Chain Broiler Protection The R-1 02 system can use two 1 nozzles for horizontal chain m. broiler protection. The nozzle is stamped 1N, indicating that this is a one-flow nozzle and must be counted as one flow number (total of two flow numbers for each chain broiler being protected). - Two 1N nozzles are always needed for chain broiler protec- tion when the hazard area to be protected does not meet the "Overhead Broiler Protection" requirements. The maximum internal size of the broiler is 43 x 31 in. (1092 mm x 787 mm). The nozzles must be positioned at each end of the enclosed cooking chamber 1 to 3 in. (25 mm to 76 mm) above the surface of the chain and a maximum distance of 4 in. (101 mm) away from the broiler opening. The nozzles may be mounted at either corner as long as they are at opposite ends of the chain broiler and positioned to discharge diagonally across the top of the chain. See Figure 4-53 and 4-54. FIGURE 4-53 FIGURE 4-52 Overhead Chain Broiler Protection The R-1 02 system can use two 1W nozzles for overhead chain broiler protection. The nozzle is stamped with 1W, indicating that this is a one-flow nozzle and must be counted as one flow number. Overhead protection is only available for chain broilers with exhaust opening dimensions that are not less than 60% of the internal broiler length and not less than 60% of the internal broiler width, to a minimum size of 12 in. x 12 in. (305 mm x 305 mm). Internal broiler size can not be larger than 32 in. x 34 in. (812 mm x 863 mm). When overhead protection is used, the nozzles must be centered above the exhaust opening within 4 to 8 in. (101 to 203 mm) of each other and they must be located 10 to 26 in. (254 to 660 mm) above the top of the broiler surface. See Figure 4-55. (101-203 mm) 10-26 IN. (254-660 mm) MAXIMUM INTERNAL BROILER SIZE 32 X 34 IN.

If the opening is not square, the nozzles must be positioned along the centerline, parallel to the longest side of the opening. See Figure 4-56.

Example No. 1 - Internal broiler size is 24 in. long x 20 in. wide (609 mm x 508 mm), with an opening of 16 in. x 16 in. (406 mm x 406 mm). To determine minimum opening size, multiply the internal length and the internal width by 0.6: Length of opening —24 in. x 0.6 = 14.4 in. (609 mm x 0.6 = 366 mm) Width of opening —20 in. x 0.6 = 12.0 in. (508 mm x 0.6 = 304 mm) The minimum allowable opening for overhead protection would be 14.4 in. x 12.0 in. (365 mm x 304 mm). This example would be acceptable for overhead protec- tion. Example No. 2 - Internal broiler size is 30 in. long x 24 in. - wide (762 x 609 mm) with an opening of 22 in. x 12 in. (558 x 304 mm). To determine minimum opening size, multiply internal length and internal width by 0.6: Length of opening —30 in. x 0.6 =18.0 in. - (762 mm x 0.6 = 457 mm) Width of opening —24 in. x 0.6 = 14.4 in. (609 mm x 0.6 = 365 mm) Minimum allowable opening for overhead protection would be 18 in. x 14.4 in. (457 mm x 365 mm). - - Because this broiler has an opening of 22 in. x 12 in. (558 mm x 304 mm), the 12 in. (304 mm) width is below the minimum allowable calculated dimension of 14.4 in. (365 mm) and therefore would not be acceptable for overhead protection. Salamander Broiler Protection The R-102 system uses three different nozzle locations for salamander broiler protection. All of the design options require a one-flow nozzle.

Schedule 40 black iron, chrome-plated, or stainless steel. Do not use hot dipped galvanized pipe on the distribution piping. All threaded connections located in and above the protected area must be sealed with pipe tape. Tape should be applied to male threads only. Make certain tape does not extend over the end of the thread, as this could cause pâssible blockage of the agent distribution. Before installing blow-off caps on nozzles, apply a small amount of Dow Coming No. 111 silicone grease across the opening in the nozzle tip and also a small amount coating the exterior of the blow-off cap. This will help keep cooking grease from building up on the cap. . Tees used in the distribution piping can be used as thru tees, side outlet tees, or bull tees.

R- 102 Restaurant Fire Suppression Manual SECTION 4— SYSTEM DESIGN UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 4-71 DETECTION SYSTEM REQUIREMENTS Once the fire suppression system design has been determined, a detection system design must be completed. This section contains guidelines and limitations for detection system instal- lation. Detector Identification The two types of detectors are distinguished from each other by their location in the detection system. The Terminal Detector is the last in a series of detectors, or the only detector used in a single-detector system. This detector is thus named because it is at the point at which the wire rope ends, or terminates." A Series Detector is any detector located in-line between the regulated release mechanism and the terminal detector. Detector/Pulley Elbow/Conduit Offset Design Limitations 1. Conduit runs, pulley elbows, and number of detectors per system must be within the approved system guidelines. The following requirements must not be exceeded: NOTICE FIGURE 4-139 000211 Maximum Maximum Maximum Number of Number of Length of Detectors Elbows 1/2 in. Conduit per System per System per System Scissors Style 15 20 150 ft (45.7 m) Detector (Without Offset Conduit Scissors Style 15 16 150 ft (45.7 m) Detector (With Offset Conduit 2. If the hazard requires more than 15 detectors, up to five 101 Remote Releases (Part No. 433485) can be used for system actuation. Each 101 remote release allows the use of a maximum of 15 "scissor' style detectors (14 series and 1 terminal) for a total of 75 detectors if needed. Detector Placement Requirements EXHAUST DUCTS Each exhaust duct must have at least one detector installed in the duct entrance, located in the airstream of the cooking vapors, or at a maximum of 20 ft (6.0 m) into the duct opening. See Figure 4-139 When gas appliances are used and the flue gases from the burner are exhausted into the duct, the detector must be kept out of the air stream of these exhaust gases. These gases can be very hot and could actuate the system unnecessarily. Duct openings that are long and narrow or large enough to require multiple duct nozzles may require additional detectors. ELECTROSTATIC PRECIPITATOR If an electrostatic precipitator is located at or near the base of the exhaust duct, it is necessary to locate a detector below the precipitator, at the base of the duct, and also locate one in the duct, just above the precipitator. See Figure 4-140. When installing the detector bracket and system conduit, make certain they do not interfere with the operation of the precipitator. Note: On secondary filtration units utilizing multiple filter stages/ e. media, contact Technical Services for instructions. FIGURE 4-140 000288 SECTION 4— SYSTEM DESIGN R- 102 Restaurant Fire Suppression Manual UL EX3470 ULC EX3470 PAGE 4-72 REV. 11 2014-SEP-01 DETECTION SYSTEM REQUIREMENTS (Continued) Detector Placement Requirements (Continued) COOKING APPLIANCES If the cooking appliance is located under an exhaust duct where a detector has been mounted, it is normally not necessary to utilize another detector for that cooking appliance, provided the detector is not more than 12 in. (304 mm) into the duct and the appliance has no larger cooking surface than 48 in. x 48 in. (11219 mm x 1219 mm). See Figure 4-141. Note: If two appliances are located under a duct opening where a detector has been mounted and both appliances together do not exceed a cooking surface of 48 in. x 48 in. (1219 mm x 1219 mm) and the detector is located above both the protected appliances, it is not necessary to utilize an additional detector provided the duct detector is not more than 12 in. (304 mm) into the duct opening. 4 APPLIANCE REQUIRES SEPARATE DETECTOR APPLIANCE COVERED BY DETECTOR UNDER DUCT APPLIANCE REQUIRES SEPARATE DETECTOR FIGURE 4.141 000209 Each cooking appliance with a continuous cooking surface not exceeding 48 in. x 48 in. (1219 x 1219 mm) can be protected by a minimum of one detector. Cooking appliances with a continu- ous cooking surface exceeding 48 in. x 48 in. (1219 x 1219 mm) must be protected by at least one detector per 48 in. x 48 in. (1219 x 1219 mm) cooking area. Detectors used for cooking appliances must be located above the protected appliance toward the exhaust duct side of the appliance. The detector should be located in the air stream of the appliance to enhance system response time. Note: For overlapping detector coverage, see Page 4-60 for design requirements. Detection Line Requirements CONDUIT Rigid conduit or 1/2 inch EMT thin-wall conduit may be used. Standard steel conduit fittings (compression type are recom- mended) must be employed to properly install the detection system. All conduit or pipe must be firmly supported. When using pipe, make certain that all ends are carefully reamed, deburred and blown clear of chips and scale before assembly. NOTICE The conduit offset can be used at the top or bottom of the regulated release to change direction of the conduit. The ôonduit offset cannot be used with pulley tees. All other changes in direction must be made by using ANSUL approved pulley elbows (Part No. 423254 or 415670). See Figure 4-142. FIGURE 4-142 000270 Fusible Link Selection When possible, temperature readings should be taken at each detector location to determine correct fusible link temperature rating. Temperature can be recorded using either a maximum registering thermometer (Part No. 15240) temperature tape or any other accurate thermometer.

R- 102 Restaurant Fire Suppression Manual SECTION 4— SYSTEM DESIGN UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 4-73 DETECTION SYSTEM REQUIREMENTS (Continued) Electric Thermal Detector When electric thermal detection is used, the detection circuit must be supervised in accordance with NFPA 17A, Standard for Wet Chemical Extinguishing Systems. Electric thermal detectors must be used in conjunction with either the AUTOPULSE 542R Control Panel (Part No. 433607) or the AUTOPULSE Z-10 Control Panel (Part No. 430525), and the 24VDC Regulated Release Assembly. Note: Consider the rate of temperature increase in the location chosen for the detector when using electric thermal detection. A transient rush of warm air up to 40 OF (4 °C) per minute may expand the shell, but not enough to trigger the AUTOPULSE control panel. Temperature increases over 40 OF (4 °C) per minute however, may initiate an alarm condition in the control panel. After determining the maximum ambient temperature at the thermal detector location, select the correct thermal detector according to the temperature condition chart in the System Components" section. MANUAL PULL STATION REQUIREMENTS A remote manual pull station allows the R-102 system to be manually operated at some point distant from the regulated release assembly. The pull station should be installed at a height of 42-48 in. (1067-1219 mm), in accordance with the require- ments of the American Disabilities Act (ADA) and the Authority having Jurisdiction, and located in the path of egress. The pull station is the only source of manual actuation of the regulated release assembly. The total length of the cable used for each manual pull station within a system must not exceed 150 ft (45.7 m). The maximum number of pulley elbows that may be used per pull station is 20. One pulley tee is allowed per cable system. The maximum length of cable from the AUTOMAN to a pull station is 150 It (45.7 m) with a maximum of 20 pulley elbows used per side of the tee. As the tee is located farther from the AUTOMAN, the 150 ft (45.7 m) maximum must be observed but as pulley elbows are placed between the AUTOMAN and the tee, they must be deducted from the available pulley elbows (20) allowed on each side. Example: If 10 pulley elbows are placed between the AUTOMAN and the pulley tee, the maximum available pulley elbows left for use on each side of the tee is 10 per side. See Figure 4-144 for three different examples. (Note: Both must be gas valves or both must be pull stations. Mixing is not allowed.) TEE CLOSE TO AUTOMAN (EXAMPLE) - PULLEY TEE 12 IN. Tmj .

The system works both mechanically and pneumatically by use of an air cylinder located inside the regulated release assembly. Upon actuation of the fire suppression system, a pneumatically-operated air cylinder assembly will mechanically close the gas shut-off valve. The total length of the cable for each mechanical gas valve must not exceed 150 ft (45.7 m). The maximum number of pulley elbows that may be used is 20 for each valve. One pulley tee is allowed per cable system. The maximum length of cable from the AUTOMAN to a gas valve is 150 ft (45.7 m) with a maximum of 20 pulley elbows used per side of the tee. As the tee is located farther from the AUTOMAN, the 150 It (45.7 m) maximum must be observed but as pulley elbows are placed between the AUTOMAN and the tee, they must be deducted from the available pulley elbows (20) allowed on each side. Example: If 10 pulley elbows are placed between the AUTOMAN and the pulley tee, the maximum available pulley elbows left for use on each side of the tee is 10 per side.

They may be mounted in any position. Pipe threads are type NPT. Ambient operating temperature range of all valves is 32 OF to 120 OF (0 °C to 49 °C). The valves are not weatherproof and must be located indoors in areas approved by the "authority having jurisdiction." R- 102 Restaurant Fire Suppression Manual ELECTRICAL GAS VALVE REQUIREMENTS A UL Listed electrically-operated gas shut-off valve can be attached to the R-102 system to provide an electrical means of shutting off the gas line at a predetermined point. If an electric gas shut-off valve is used in the system it must be attached with both an electric (snap-action) switch and a manual reset relay. For more information on the types of electric (snap-action) switches, refer to the Electrical Switch, Field Installation section. - The manual reset relay is reviewed in this section. All electrical connections should be performed by a QUALIFIED ELECTRICIAN and in accordance with authority having jurisdiction. The following is a brief explanation of how the R-102 system operates with an Electric Gas Shut-off Valve attached: With the regulated release cocked in the ready condition, the normally closed contacts in the snap-action switch allow current to flow to the manual reset relay. With the relay coil energized, normally open contacts in the reset relay close, allowing the solenoid in the gas valve to be energized. Once the R-102 system is activated, the normally closed contacts in the snap-action switch will open, de-energizing the reset relay. This will, in turn, open the contacts in the relay which will cause the gas valve to become de-energized and close. The system must be re-armed and the "push to reset" button on the reset relay must be operated to reopen the gas valve. It is important to note that a power failure or an electrical power interruption will cause the gas valve to close even though the system was not fired. In either case, whether in a fired condition or when a power failure has occurred, the manual reset relay and electric gas shut-off valve must be reset to resume a normal operating condi- tion. For resetting, refer to the "Recharge and Resetting Procedures" section in this manual.
