The agent is shipped in plastic containers which provide one complete tank charge. Agent storage life expectancy is twelve years and can be stored at a temperature of -40 °F to 130 °F (-40 °C to 54 °C). When installing agent in R-102 system, temperature range is 32 °F to 130 °F (0 °C to 54 °C). The distributor must record the batch numbers and date of shipment receipt to be filed with each installation record. ANSULEX LOW PH LIQUID FIRE SUPPRESSANT 3.0 GAL 1.5 GAL SHIPPING WT. 35 LB (15.9 kg) SHIPPING WT. 19 LB (8.6 kg) FIGURE 3-1 010892, 000137 AGENT TANK ASSEMBLY The Agent Tank Shipping Assembly (3 gal (Part No. 429862) and 1.5 gal (Part No. 429864)) consists of a stainless steel tank and an adaptor/tube assembly. The adaptor/tube assembly contains a burst disc. The burst disc prevents agent leakage due to significant temperature fluctuations in the area where the tank is located. Under normal conditions, the tank requires hydrostatic testing every twelve years. The date of manufacture is printed on the tank nameplate. The tank is shipped uncharged and must be filled with only ANSULEX Low pH Liquid Fire Suppressant during installation. FIGURE 3-2 AGENT TANK TANK ADAPTOR/ TUBE ASSEMBLY 3 GAL SHIPPING WT. 7 LB (3.2 kg) 1.5 GAL SHIPPING WT. 5 LB (2.3 kg) 000140 REGULATED RELEASE ASSEMBLY (MECHANICAL) The AUTOMAN Regulated Mechanical Release Assembly (Part No. 429853) contains the regulated release mechanism, expellant gas hose for agent tank hookup, and enclosure knockouts to facilitate installing actuation piping, expellant piping, detection system, and additional equipment. 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 expellant 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 enclosure contains the required knockouts to facilitate this connection. 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.

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 strings the wire rope completely through the detection system conduit and brackets first and the detector linkage assemblies are then clipped on later. The detection line 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. Note: Scissor-style linkage is also available in a 10-Pack (Part No. 439515).

Once this is established, the correct rated fusible link can be chosen. Other methods for determining maximum temperatures may be used. HOSE/GROMMET PACKAGE The Hose/Grommet Package (Part No. 418511) consists of a 24 in. (610 mm) rubber hose and two grommets. This package is required when expellant gas hose is routed outside the AUTOMAN Regulated Release, Regulated Actuator, and/or tank enclosure assemblies. IN-LINE BURST DISC ASSEMBLY (MANIFOLDED SYSTEMS ONLY) The In-Line Burst Disc Assembly (see Table 3-15 and Figure 3-39) 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. The Burst Disc Assembly is to be used in a manifolded system and it is necessary to modify or 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.

Those individuals responsible for the design of the R-102 system must be trained and hold a current ANSUL® 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. 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 appropriate 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 sub-sections: • Noz zle Placement Requirements • Tank and Cartridge Requirements • Actu ation and Expellant Gas Line Requirements • Distribution Piping Re quirements • Detection System Requirements • Manual Pull Sta tion Requirements • Mechanical Gas Valve Requirements • Electri cal Gas Valve Requirements • Alarm Initiating Switch Requirements • Electrical 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. Note: Ducts from multiple hoods connected to a common ductwork must be protected in compliance with NFPA 17A and all local codes. The R-102 system uses different duct nozzles depending on the size of duct being protected. GENERAL INFORMATION 1. Nozzles must be located 2 in. to 8 in. (51 mm to 203 mm) into the center of the duct opening, discharging into the opening. See Figure 4-1. FIGURE 4-1 2 IN. TO 8 IN. (51 mm TO 203 mm) 000173 2. In installations where a UL Listed damper assembly is employed, install the duct nozzle beyond the 8 in. (203 mm) maximum, to a point just beyond the damper assembly that does not interfere with the damper. Exceeding the maximum of 8 in. (203 mm) in this way does not void the UL Listing of the system. 3. 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.

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.
