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- ant 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.

(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).

SECTION 3 - SYSTEM COMPONENTS UL EX3470 ULC EX3470 PAGE 3-12 REV. 11 2014-SEP-01 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 (remov) the burst disc located in all of the R-1 02 tank adaptors in the system. The in-line burst disc assembly is to be mounted as cicse to the tank outlet as possible. After system discharge, the assembly must be disassembled and a new burst disc installed.

NPT Male R- 102 Restaurant Fire Suppression Manual DESIGN The ANSUL R-102 Restaurant Fire Suppression System maybe 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-102 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. FN'OZZLE 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. tectiór Single NOZZIfl 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. Note: Ducts from multiple hoods connected to a common ductwork must be protected in compliance with NFPA 96 and all local codes. The R-1 02 system uses different duct nozzles depending on the size of duct being protected. 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. 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.

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.

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.

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. A. 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 flypot 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 fryer and the positioning requirements allowed. Refer to appropriate Figures.

Refer to Distribution Piping Requirements - 9.0 Gallon System, page 4-70 for additional design requirements. DISTRIBUTION PIPING REQUIREMENTS Once 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.

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. a CENTER TO CENTER REGULATED ACTUATOR ASSEMBLY FIGURE 4-125 OUD777 2.

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-oft caps on nozzles, apply a small amount of Dow Corning No. 111 silicone grease across the opening in the nozzle tip and also a small amount coating the exterior of the blow-oft 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.

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 ODD271 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/ P. media, contact Technical Services for instructions.

(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 prctected 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 Q2 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 contiru- 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 detectcr 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 reccm- mended) must be employed to properly install the detect on 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 ODD270 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. &4~D AN3U..

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 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.

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.
