FIGURE 2-2 008321 R- 102 Restaurant Fire Suppression Manual SYSTEM DESIGN The ANSUL R-102 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-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. SECTION 4 - SYSTEM DESIGN UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 4-1 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.

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.) 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. (26-508 mm) above the top edge of the filter. See Figure 4-7. FIGURE 4-7 000199 SECTION 4 - SYSTEM DESIGN UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 4-5 Option 2: The 1W nozzle must be placed perpendicular, 8-12 in.

One of the applications requires a 1-flow nozzle and three of the applications require a 2-flow nozzle. High Proximity Application: 35 in. to 40 in. (889 to 1016 mm) above the cooking surface. This high proximity application uses the 1 nozzle. The nozzle is stamped with 1 indicating this is a one-flow nozzle and must be counted as one flow number. One 1 nozzle will protect a maximum cooking area of 1080 in.2 (69677 mm2) with the maximum longest side of 36 in. (914 mm). When using this nozzle for griddle protection, the nozzle must be positioned along the cooking surface perimeter to a maximum of 2 in. (50 mm) inside the perimeter, and aimed to the midpoint of the cooking surface. See Figure 4-39 and 4-40. NOTICE When using this type of griddle protection, only five flow numbers are allowed on a 1.5 gal (5.7 L) system and only ii flow numbers are allowed on a 3 gal (11.4 L) system. t MIDPOINT OF I lii COOKING SURFACE + I ill Ill III J I I IN NOZZLE LOCATED ALONG COOKING ANY SIDE OF GRIDDLE SURFACE WITHIN SURFACE 0-2 IN.

(381 mm to 508 mm) above the cooking surface. The low proximity 1-flow nozzle application for the protection of griddles requires the 1W nozzle. The nozzle is stamped with 1W indicating that this is a one-flow nozzle and must be counted as one flow number. When using the 1W nozzle for low proximity griddle protection with our without obstruction, the maximum length of the cooking surface to be protected must not exceed 26 in. (660 mm). The nozzle must be centered at one end of the maximum 26 in. (660 mm) length, aimed along a centerline to a point 20 in. (508 mm) from the end of the length, protecting a maximum width of 20.5 in. (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. Chain Broiler Protection The following listed protection guidelines can be applied to any manufacturer's chain broilers, if the chain broiler meets the specified parameters. 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 1N 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-102 system can use two 1 nozzles for horizontal chain b. 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.

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 000271 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 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 2. If the hazard requires more than 15 detectors, up to five 101 Remote Releases (Part No. 433485) can be used for If an electrostatic precipitator is located at or near the base of system actuation. Each 101 remote release allows the use the exhaust duct, it is necessary to locate a detector below the of a maximum of 15 scissor" style detectors (14 series and precipitator, at the base of the duct, and also locate one in the 1 terminal) for a total of 75 detectors if needed. duct, just above the precipitator. See Figure 4-140. 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 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/ o. media, contact Technical Services for instructions. li,.

(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 REQUIRES SEPARATE DETECTOR APPLIANCE COVERED BY DETECTOR UNDER DUCT APPLIANCE REQUIRES SEPARATE DETECTOR FIGURE 4-141 000269 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 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. 94D TEMPERATURE RATING STAMPED ON FUSIBLE LINK BODY o ==4=/1- 000170 000111 SL STYLE A-PC STYLE FIGURE 4-143 Select correct UL Listed fusible link(s) for installation in detec- tor(s) according to the temperature condition. Two styles are available. See Figure 4-143. See Component Section for detailed temperature ratings. R- 102 Restaurant Fire Suppression Manual DETECTION SYSTEM REQUIREMENTS (Continued) r 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 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.

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: 1110 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 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. R- 102 Restaurant Fire Suppression Manual ELECTRICAL GAS VALVE REQUIREMENTS (Continued) Approvals ANSUL gas valves listed in this section are UL listed and approved for 110 VAC. If more information is required, refer to the Gas and Oil Equipment List of Underwriters Laboratories, Inc. under 'Electrically Operated Valves Guide No. 440 A5" or consult Tyco Fire Protection Products, Marinette, Wisconsin 54143-2542. If other gas valves are used, they shall be "UL listed electrical- ly-operated safety valves for natural or LP gas as required, of appropriate pressure and temperature rating, 110 VAC/60 Hz." The information on temperature and type of gas that the valves are suitable for may be found in the Gas and Oil Equipment List of Underwriters Laboratories, Inc. under Electrically Operated Valves Guide No. 440 A5." The electrically operated gas valve must be of the type that needs to be energized to remain open. SECTION 4 - SYSTEM DESIGN UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 4-75 ELECTRICAL SWITCH REQUIREMENTS Note: Electrical connections shall not be made in the AUTOMAN. The electric (snap-action) switches for the R-102 system are specially designed to fit the regulated release assembly. The switches are intended for use with electric gas valves, alarms, contactors, lights, contractor supplied electric power shut-off devices, and other electrical devices that are designed to shut off or turn on when the fire suppression system is actuated. (See Figures 5-122 through 5-124 in Installation Section for reference). Contractors shall supply "UL listed, enclosed industrial control equipment or magnetic switch having a rating matching that of the cooking appliance, coil 110 VAC/60 Hz or 24 VAC/60 Hz." All electrical connections should be performed by a QUALIFIED ELECTRICIAN and in accordance with authority having jurisdiction.
