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 e~her 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 oombination 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 w~ the same type of system, e~er R-102 or PIRANHA, unless the center-to-center spacing between the adjacent R-102 and PIRANHA nozzles is no less than 36 inches. • 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. SECTION IV -SYSTEM DESIGN UL EX. 3470 ULC CEx747 Page 4-1 4-1-06 REV. 6 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. (5-20cm) FIGURE 1 2. In installations where a UL listed damper assembly ls employed. the duct nozzle can be installed beyond the 8 in. (20 cm) maximum, to a point just beyond the damper assem­ bly that wm not interiere with the damper. Exceeding the maxi­ mum of 8 in. (20 cm) in this way will not void the UL listing of the system. 3.

(1.2 m) wide of "V" bank plenum. The nozzles must be mounted in the plenum, 2 to 4 in. (5 to 1 O 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.

(5-10cm) FIGURE 11 For a plenum, either single or "V" bank, with a linear extension longer than 10 feet (3.1 m), each bank may be protected using one 1N 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 10ft. (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. 10FT.(3.1 m)/ MAXIMUM FIGURE 12 10FT.(3.1 m)/ MAXIMUM FT.

(122 x 122 cm) can be protected by a min­ imum of one detector. Cooking appliances with a continuous cook­ ing surface exceeding 48 in. x 48 in. can be protected by at least one detector per 48 in. x 48 In. cooking area. Detectors used for cooking appliances must be located above the protected appli­ ance 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 4-42 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 recommend­ ed) 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 condurt offset can be used at the top or bot­ tom of the regulated release to change direction of the conduit. The conduit offset cannot be used with pulley tees. All other changes in direc­ tion must be made by using ANSUL approved pulley elbows, Part No. 423254 or 415670.
