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-1 02 system must be trained and hold a current ANSUL certificate in an R-1 02 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. Duct Protection - Single Nozzle All duct protection is UL listed without limitation of maximum duct length (unlimited length). This includes all varieties of ductworks both horizontal and vertical including ducts that run at angles to the horizontal and ducts with directional bends. GENERAL INFORMATION 1. Nozzles must be located 2-8 in. (51-203 mm) into the center of the duct opening, discharging up. See Figure 4-1. 2-8 IN. (51 - 203 mm) FIGURE 4-1 000173 In installations where a UL listed damper assembly is employed, the duct nozzle can be installed beyond the 8 in. (203 mm) maximum, to a point just beyond the damper assembly that will not interfere with the damper. Exceeding the maximum of 8 in. (203 mm) in this way will not void the UL listing of the system. Previously listed three flow number and five flow number duct protection detailed in earlier published manual (Part No. 418087-06) can also still be utilized. DUCT SIZES UP TO 50 IN.

(203 mm) wide and a "B" dimension of 55 in. (1397 mm) long. Referring to the table in Figure 2, if the "A" dimension is 8 in. (203 mm), the "B" dimension must not exceed 58.5 in. (1485 mm). In this example, the "B" dimension is 55 in. (1397 mm), therefore, this duct can be protected with a three flow application. R- 102 Restaurant Fire Suppression Manual Read over from the 8.0 in. (203 mm) line on the table to the 1W Module column. At that point, the chart shows that the "B" module length for the 1W nozzle can be 22.0 in. (558 mm). Center the 1W nozzle in that module. The 2W module can now be centered within the remaining module. R- 102 Restaurant Fire Suppression Manual Duct Protection — Multiple Nozzle (Continued) DUCT SIZES GREATER THAN 100 IN. (2540 mm) PERIMETER Ducts over 100 in. (2540 mm) perimeter may be modularized using 2W nozzles No round duct option available Follow the design chart to determine maximum module size for each 2W nozzle When determining number of nozzles required, it is sometimes an advantage to check the chart using the shortest side as Side 'A" and then recheck it using the longest side as Side "A." This comparison may reveal a need for a lesser quantity of nozzles one way versus the other way. When working with Chart 4-1, the quantity of nozzles deter- mined must be equally divided within the duct area. SECTION 4— SYSTEM DESIGN UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 4-3 When working with Chart 4-2, one half of the quantity of nozzles determined must be equally positioned in the top half of the area of the duct and the remaining half of the nozzles must be positioned in the bottom half of the duct area. Example: The duct to be protected has a Side "A" of 40 in. (1016 mm) and a Side "B" of 60 in. (1524 mm). Referring to the deign chart, this duct requires four nozzles. One half of 4 = 2. Therefore, two nozzles must be equally positioned in each of the two duct areas. See Figure 4-3. SIDE 'B" 30 IN. (762 mm) 30 IN. (762 mm) 201N. • . - I (508 mm) SIDE I 40 IN.

The nozzle(s) must be located in the center of the area at that point, or center of the module protected when more than one duct nozzle is required. Note: Nozzles to protect ducts with a transition that is more than 4 ft (1.2 m) in height, will be required to be positioned in the opening of the transition from the hood 2 to 8 in. (50 to 203 mm) into the opening using standard duct nozzle design parameters. See Figure 4-4. R-102 Restaurant Fire Suppression M'anual The 1/2N nozzle must be centered 10 to 26 in. (254 to 660 mm) below the precipitator and aimed to discharge at the center of each precipitator cell. However, if it is physically impossible to mount the nozzle at 10 to 26 in. (254 to 660 mm) due to precip- itator placement, the nozzle may be mounted closer than 10 in. (254 mm). See Figure 4-5.

These precipitators are generally small and are used to aid in the cleaning of exhaust air. Ducts with precipitators located at or near the base can be protected using duct nozzle(s) above the precipitator and 1/2N nozzle(s) for the precipitator. One 112N nozzle must be used for each cell being protected. This nozzle is stamped with 112N, indicating that it is a 1/2-flow nozzle and must be counted as 1/2 flow number. When protecting ducts equipped with precipitators, the duct nozzle(s) must be installed above the precipitator and aimed to discharge downstream. If the area above the precipitator is a duct, the nozzle(s) must be positioned according to duct protec- tion guidelines. If the area above the precipitator is a transition, the transition guidelines must be followed. Note: For protection of Pollution Control Units (PCUs) or air scrubbers with or without ESPs, contact Technical Services for non-UL listed recommended application. ME R-102 Restaurant Fire Suppression Manual Plenum Protection The R-102 system uses the 1W nozzle or the IN nozzle for plenum protection. The 1W nozzle is stamped with 1W and the 1 N nozzle is stamped with 1 N, indicating they are one-flow nozzles and must be counted as one flow number each. When protecting a plenum chamber, the entire chamber must be protected regardless of filter length. VERTICAL PROTECTION - GENERAL 1W NOZZLE - SINGLE AND "V' BANK PROTECTION One 1W nozzle will protect 4 linear feet (1.2 m) of plenum. 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.)

The nozzle must be positioned 0-6 in. (0-152 mm) from the end of the hood to the tip of the nozzle. See Fiqure 4-9. 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. (26-508 mm) above the top edge of the filter. See Figure 4-7. 2 4 (50- 000201 FIGURE 4-9 (508 mm) UM FIGURE 4-7 000199 For a plenum, either single or "V' bank, with a linear extension P. longer than 10 ft (3.0 m), each bank may be protected using one 1 N 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. 0. 0. P. P.

See Figure 4-11. 0. 01 2 rT FIGURE 4-11 R-102 Restaurant Fire Suppression Manual Appliance Protection The following pages detail types of appliance protection. 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 fryer 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 fiyer and the positioning requirements allowed. Refer to appropriate Figures. I SECTION 4— SYSTEM DESIGN UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 4-7 R-102 Restaurant Fire Suppression IVianual Nozzle Height Above Top of Fryer 27 in. to 47 in.

Each module must not exceed the maximum area allowed for a single nozzle. However, when utilizing multi- ple nozzle protection, the longest side allowed for a fryer with dripboard can be used, regardless of whether the fryer has a dripboard or not. The maximum size fryer that can be modularized is 864 in.2 (55742 mm2). 1. Design requirements for multiple nozzle fryers are broken down into two types: FRYERS WITHOUT DRIPBOARD(S) If the fryer does not include a dripboard, measure the internal depth (horizontal dimension from front to back) and length of the frypot. Then, multiply the depth and length to obtain the area of the frypot in square inches. FRYERS WITH DRIPBOARD(S) If the fryer includes any dripboard areas, measure both the internal depth and length of the frypot portion, and then measure the internal depth and length of the overall hazard area including any dripboard areas. Determine the area of both the frypot and the area of the overall vat by multiplying corresponding depth and length dimensions. 2. Divide the frypot or overall vat into modules, each of which can be protected by a single nozzle, based on the maximum dimension and area coverage of the nozzle as specified in Table, "Maximum Cooking Area Dimension - Multiple Nozzle Protection." R-102 Restaurant Fire Suppression Manual If the module considered does not include any portion of the dripboard, use only the maximum frypot area and maximum dimension listed in the first column of the table to select the correct nozzle. If the module considered includes any dripboard areas, use both the maximum frypot area and dimension listed in the first column of the table, and the maximum overall area and dimensions listed in the second column of the table to select the correct nozzle. 3. None of the maximum dimensions in either column may be exceeded. If either the maximum frypot or the overall sizes are exceeded, the area divided into modules will need to be redefined with the possibility of an additional nozzle. Options For Modularizing Fryers The following Figure 4-20 shows approved methods of divid- ing (modularizing) fryers so that each section can be properly protected. Example: A fryer with a dripboard. The inside vat without the dripboard measures 18 in. in depth x 30 in. in length (457 mm x 762 mm) and the inside of the overall vat includ- ing the dripboard measures 24 in. in depth x 30 in. in length (610 mm x 762 mm). Because the fryer is 30 in. (762 mm) in length, it exceeds the coverage of a single nozzle. Dividing the length in half, each module now has an overall vat dimension of 24 in. in depth x 15 in. in length (610 mm x 381 mm). From the Table, "Maximum Cooking Area Dimension - Multiple Nozzle Fryer Protection," either the 3N or the 29C nozzle should be selected to protect each fryer module, depend- ing on the maximum nozzle height above the fryer and the positioning requirements allowed. Refer to appropriate Figures, 4-15 through 4-19. See additional examples in Appendix Section. EACH MODULAR AREA, INCLUDING DRIPBOARD, MUST NOT EXCEED 497 IN.'

Refer to Section IV, DESIGN, starting on Page 4-10, for maximum fryer nozzle coverages and maximum fryer nozzle height limitations. Although the maximum 864 in.2 (55741 mm2) total surface cooking area requirement applies to fryer protection, it does not apply to tilt skillets or braising pans. Each tilt skillet/braising pan protected module must not exceed the fryer limitations for "MAXIMUM SIZE MODULE OVERALL WITH DRIPBOARD" coverage per nozzle as described in Table on Page 4-11. Tilt skillets and braising pans generally utilize a hinged cover. Fryer protection nozzles are to be placed toward the front of the appliance to minimize the potential for the tilt skillet or braising pan cover to interfere with the nozzle discharge. See Figures 4-25 and 4-26. THE NOZZLE IS TO BE PLACED TOWARD THE FRONT OF THE APPLIANCE TO MINIMIZE THE POTENTIAL. FOR THE SKILLET OR BRAISING PAN COVER TO INTERFERE WITH THE NOZZLE DISCHARGE.

Horizontal Chain Broiler Protection The R-102 system can use two 1 nozzles for horizontal chain o. broiler protection. The nozzle is stamped iN, 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 iN 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 MAXIMUM INTEF BROILER SIZE 4I (1092 X 787 mm) FIGURE 4-54 000247 The R-102 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. 12 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. TOP VIEW TOP VIEW FIGURE 4-56 000249 Note: The Metal Blow-off Cap must be used when utilizing chain broiler protection. 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. SIN.

Certain models of the Nieco broiler (Models 940, 962, and 960) are equipped with a catalytic converter to comply with new clean air laws. Because of the converter, it is necessary to protect these broilers in a special way. The guidelines for protecting these broilers are as follows: - The maximum internal broiling area is 29 in. x 23.5 in. (737 mm x 596 mm). - An R-102 3-gallon system with a maximum of six flow numbers, must be used for protection of each broiler, includ- ing plenum and duct. - Each individual broiler must be protected with a minimum of two iN nozzles. The nozzles must be located as shown in Figure 4-88. - The broiler must be fitted with two 1 in. (25 mm) high agent barriers on the angled surface of the broiler. If these have not been completed by the equipment supplier, they must be added in the field. 30* (2) IN NOZZLES U 14.25±1 IN. (362 mm ±25 mm) -- 12 IN. TO 13 IN.

(152 mm) inside the outside edge of the cooking hazard of each end appliance, and the inside overlapping nozzles must be located between the two end nozzles at a maximum spacing of 12 in. (304 mm). Hazard Zone The hazard zone is defined as a theoretical, flat and level, rect- angular surface, that includes all of the cooking hazards of the protected appliances under a common hood(s). The purpose of the hazard zone is to provide a means of locating the appliances and the overlapping nozzles, as well as aiming the overlapping nozzles. The hazard zone measures 28 in. (711 mm) deep by the length of the cooking hazard(s). The centerline of the hazard zone must bisect the 28 in. (711 mm) depth (from front to back) and run from right-to-left for the full width of the hazard zone. Overlapping Nozzle Appliance Protection Overlapping Nozzle Appliance Protection is defined as protec- tion of cooking appliances by nozzles spaced uniformly at uniform elevations under a common hood(s). Overlapping protection of appliances is continuous for the full length of the hood or divided when group(s) of protected appliances are separated by counters or appliances not requiring protection. Full hood continuous protection is defined as overlapping nozzle appliance protection that covers the appliance line-up located under the total hood length. All appliances requiring protection are the appliances under the hood that can be an igni- tion source of grease in the hood, grease removal device or the duct. Group protection is defined as overlapping nozzle appliance protection that protects individual hazard zones located under a common hood. These "groups" of appliances may be separated by appliances not requiring protection, such as steam equipment or work tables, or by dedicated appliance protection, such as salamander broilers. See Figure 4-108 (full hood continuous protection) and Figure 4-109 (multiple group protection). Dedicated Nozzle Appliance Protection Appliance protection using dedicated nozzle coverage is defined as protection of cooking appliances with enclosed cooking hazards, such as upright broilers, which cannot be protected with overlapping nozzles and therefore must be protected with nozzles dedicated to the appliance. General Design Limitations Maximum depth of zone is 28 in. (711 mm). The 245 nozzle is the only approved nozzle for overlapping (zone) protection. Nozzle must be located 0 in. to 6 in. (0 mm to 152 mm) forward of zone centerline, aimed back at the zone centerline. Nozzles must be spaced a maximum of 6 in. (152 mm) from each end of hazard and then a maximum of 12 in. (304 mm) on center for the remaining overlapping nozzles until the complete hazard is covered.

The overlapping nozzle is used for both continuous overlapping and multiple group overlapping protection. The hazard zone must be positioned (located) so that all appliance hazard surfaces are within the zone. For appli- ance hazard surfaces with listed protection exceeding the standard hazard zone size of 28 in. (711 mm) in depth (see Table 1), the hazard surface(s) must be aligned with the back edge of the hazard zone, with the front edge overhang- ing the front of the zone. The overlapping appliance nozzles must be located 40 in. to 45 in. (1016 mm to 1143 mm) above the top surface of the protected appliances. See Figure 4-107. Exception No. 1: Nozzle dimensions for wok protection are measured to bottom of wok. Exception No. 2: When using overlapping appliance nozzles in areas where there is a back shelf, the nozzle cannot be positioned in the shaded area as shown in Figure 4-106. Also, back shelf must not extend more than 11 in. (279 mm) over the hazard zone and cannot be less than 20 in. (508 mm) above the hazard zone.

(292 mm) inside the outside edge of the cooking hazard of each end appliance, and the inside overlapping nozzles must be located between the two end nozzles at a maximum spacing of 25.5 in. (647 mm). Hazard Zone The hazard zone is defined as a theoretical, flat and level, rect- angular surface, that includes all of the cooking hazards of the protected appliances under a common hood(s). The purpose of the hazard zone is to provide a means of locating the appliances and the overlapping nozzles, as well as aiming the overlapping nozzles. The hazard zone measures 28 in. (711 mm) deep by the length of the cooking hazard(s). The centerline of the hazard zone must bisect the 28 in. (711 mm) depth (from front to back) and run from right-to-left for the full width of the hazard zone. Overlapping Nozzle Appliance Protection Overlapping Nozzle Appliance Protection is defined as protec- tion of cooking appliances by nozzles spaced uniformly at uniform elevations under a common hood(s). Overlapping protection of appliances is continuous for the full length of the hood or divided when group(s) of protected appliances are separated by counters or appliances not requiring protection. Full hood continuous protection is defined as overlapping nozzle appliance protection that covers the appliance line-up located under the total hood length. All appliances requiring protection are the appliances under the hood that can be an ignition source of grease in the hood, grease removal device or the duct. Group protection is defined as overlapping nozzle appliance protection that protects individual hazard zones located under a common hood. These "groups" of appliances may be separated by appliances not requiring protection, such as steam equipment or work tables, or by dedicated appliance protection, such as salamander broilers. See Figure 4-116 (full hood continuous protection) and Figure 4-117 (multiple group protection). Dedicated Nozzle Appliance Protection Appliance protection using dedicated nozzle coverage is defined as protection of cooking appliances with enclosed cooking hazards, such as upright broilers, which cannot be protected with overlapping nozzles and therefore must be protected with nozzles dedicated to the appliance. General Design Limitations If overlapping appliance protection is mixed with dedi- cated appliance protection on the same pipe system, THE OVERLAPPING APPLIANCE PROTECTION PIPING REQUIREMENTS MUST BE FOLLOWED. Overlapping protection requires the use of 3.0 gal (11.4 L) tank(s) and a maximum of six flows per tank. In installations using tanks only intended for overlapping protection, a single Double Tank nitrogen expellant gas cartridge can be utilized with up to three 3.0 gal (11.4 L) tanks. In installations using both overlapping protection and conven- tional non-overlapping protection (ex. hood/duct or dedicated appliance protection), a single Double Tank nitrogen expellant gas cartridge can be utilized with up to three 3.0 gal (11.4 L) tanks, as long as none of the 3.0 gal (11.4 L) tanks exceed a total flow output of more than six flows. If more than six flows will be used in a conventional non-over- lapping tank, it cannot share the same cartridge as tanks Intended for overlapping protection. In this case, an additional Regulated Actuator Assembly with another expellant gas cartridge will be required. The 245 nozzle must be used for "end of zone" protection. The 260 nozzle must be used for zone protection. Maximum depth of zone is 28 in. (711 mm). Refer to overlapping system piping requirements listed in Table 4-2. Nozzle must be located 0 in. to 12 in. (0 mm to 304 mm) forward of zone centerline, aimed back at the zone centerline. Nozzles must be spaced a maximum of 11.5 in. (292 mm) from each end of hazard and then a maximum of 25.5 in. (647 mm) on center for the remaining overlapping nozzles until the complete hazard is covered. For appliance hazard surfaces with listed protection exceed- ing the standard hazard zone of 28 in. (711 mm) in depth, the hazard surface(s) must be aligned with the back edge of the hazard zone, with the front edge overhanging the front edge of the zone. See Appliance Chart, Table 4-1. For appliance hazard surfaces that exceed the listed protec- tion sizes, multiple zones must be utilized. Align entire hazard surface area within the multiple zones. 'All hood, duct, and individual appliance protection are as spec- ified in the R-102 Design, Installation, Recharge and Mainten- ance Manual (Part No. 418087). All appliance protection currently listed in the R-102 Design Manual (Part No. 418087) is also approved protection. Zone 'protection can be considered optional protection.

Refer to Distribution Piping Requirements - 9.0 Gallon System, page 4-70 for additional design requirements. DISTRIBUTION PIPING REQUIREMENTS Orjlce the nozzle placement and quantity of tanks has been determined, it is then necessary to determine the piping config- urations between the tank adaptor and each discharge nozzle. This section contains the guidelines and limitations for designing the distribution piping so that the liquid agent will discharge from the nozzles at a proper flow rate. These limitations should also be referred to when selecting the mounting location for the regu- lated release mechanism and agent tank.

OF FITTINGS -9 AUTOMAN REGULATED RELEASE ASSEMBLY FIGURE 4-124 000776 All R-102 system piping is straight line. Therefore, the need for critical lengths and balancing is minimized. Two 450 elbows count as one 900 elbow. Each branch line includes the tee or elbow leading to it, and all fittings within the branch line itself. The minimum piping length of Schedule 40, 3/8 in. pipe from the tank outlet to any nozzle protecting a range, fryer, or wok must be 6 ft (1.9 m). Pipe lengths are measured from center of fitting to center of fitting. See Figure 4-126. CENTER TO CENTER REGULATED ACTUATOR ASSEMBLY FIGURE 4-126 000777 2. A combined total of nine fittings may be used in these lines, eight 900 elbows and one tee. Two 450 elbows equal one 900 elbow. FIGURE 4-126 000778 . All distribution piping must be 3/8 in. 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 possible 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.

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 dupt, just above the precipitator. See Figure 4-140. Men installing the detector bracket and system conduit, make ceiiain they do not interfere with the operation of the precipitator.

FIGURE 4-140 000268 R-162 Restaurant Fire Suppression Manual 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: 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 SECTION 4— SYSTEM DESIGN UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 4-71 SECTION 4— SYSTEM DESIGN R-102 Restaurant Fire Suppression Manuel 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. (1219 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. APPLIANCE APPLIANCE APPLIANCE REQUIRES COVERED BY REQUIRES SEPARATE DETECTOR SEPARATE DETECTOR UNDER DUCT DETECTOR FIGURE 4-141 000289 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 conduit 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 020270 Fusible Link Selection When possible, temperature readings should be taken at each detector location to determine correct fusible link temperature rating.

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 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 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.) SECTION 4— SYSTEM DESIGN UL EX3470 ULO EX3470 PAGE 4-74 REV. 11 2014-SEP-01 MECHANICAL GAS VALVE REQUIREMENTS An ANSUL or ANSUL approved mechanical gas shut-off valve system can be attached to the R-1 02 system. 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 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.

R-102 Restaurant Fire Suppression Mnui 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.
