This regulated release assembly is used in single, double, and multiple-tank systems and must be mounted to a rigid surface. The release mechanism can be used to interconnect both the actuation and expellant 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 expel- lant gas hose connects the agent tank to the bottom outlet of the regulator. In double and multiple-tank system configurations, the back outlet of the regulator is used as an expellant gas feed for one additional tank-enclosure or tank-bracket hookup. The enclo- sure contains the required knockouts to facilitate this connection. If a pressure switch is to be attached to the regulator, additional fit- tings 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 conditions, 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 detection 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 sometimes 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. 'Note: Series Detector, Part No. 435547, is also available as Part No. 435548, 25/Pkg. SCISSOR STYLE - PART NO. 435546 AND 435547 PULLEY TEE The Pulley Tee (Part No. 427929) is used to change the direction of two wire ropes by 90°.

In addition to eliminating the siphoning effect, the common in-line burst disc assembly eliminates the possibility of one or more indi- vidual 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 assem- bly is to be mounted as close to the tank outlet as possible. After system discharge, the assembly must be disassemblec and a new burst disc installed.

SECTION IV - SYSTEM DESIGN UL EX3470 ULC EX3470 Page 4-1 7-1-09 REV.8 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-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 ANSUL AUTOMAN Release can be either an R-102 or a PIRANHA ANSUL 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-1 02 and PIRANHA nozzles is no less than 36 in. (91.4 cm). When appliances are protected with R-102 nozzles, the hood and connecting duct above those appliances cannot be pro- tected 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 ten sub-sections: Noz- zle Placement Requirements, Tank Quantity Requirements, Actu- ation and Expellant Gas Line Requirements, Distribution Piping Requirements, Detection System Requirements, Manual Pull Sta- tion Requirements, Mechanical Gas Valve Requirements, Electri- cal 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 quantity 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. The R-102 system uses different duct nozzles depending on the size of duct being protected. GENERAL INFORMATION 1. Nozzles must be located 2-8 in. (5-20 cm) into the center of the duct opening, discharging up. See Figure 1. 2-8 IN. (5-20 cm) FIGURE 1 000173 In installations where a UL listed damper assembly is employed, the duct nozzle can be installed beyond the 8 in. (20 cm) maximum, to a point just beyond the damper assem- bly that will not interfere with the damper. Exceeding the maxi- mum of 8 in. (20 cm) in this way will not void the UL listing of the system. Previously listed 3 flow number and 5 flow number duct pro- tection detailed in earlier published manual, Part No. 418087- 06, can also still by utilized. DUCT SIZES UP TO 50 IN.

The nozzles must be mounted in the plenum, 2 to 4 in. (5 to 10 cm) from the face of the filter, centered between the filter height dimension, and aimed down the length. The nozzle must be positioned 0-6 in. (0-15 cm) from the end of the hood to the tip of the nozzle.

The nozzle must be mounted horizontally, positioned 1/3 the filter height down from the top of the filter. Nozzles can be located at 6 It (1.8 m) spacings on longer plenums. The nozzle must be positioned 0-6 in. (0-15 cm) from the end of the hood to the tip of the nozzle. See Figure 10. For a plenum, either single or "V' bank, with a linear extension longer than 10 ft (3.1 m), each bank may be protected using one iN nozzle every 10 ft (3.1 m) or less depending on the overall length of the plenum. See Figure 12. The nozzles may point in the opposite directions as long as the entire plenum area is protected, and the 10 ft (3.1 m) limitation is not exceeded. See Figure 13. The nozzle positioning shown in Figure 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.
