Cylinder sizes are based on the flow point capacity of the cylinder, for example, the BFR -5 is capable of supporting a maximum of five (5) flow points. All cylinders are manufactured, marked, and tested in accordance with DOT 4BW240. Each cylinder is shipped pre - filled with extinguishing agent, and charged with dry nitrogen to a pressure of 195 psig (1344 KPa) @ 70° F (21° C). Cylinder and valve assembly dimensions are shown in Figure 2 -1. Note: Cylinders shall always be stored in an upright position. Figure 2 -1. Cylinder and Valve Assembly Dimensions.

The Systems Releasing Module will support the following system inputs and outputs: • One Fusible Link Detection Line • One Gas Valve Line • One Remote Pull Station Line Two windows in the front cover of the Model SRM allow for visual verification of the actuation cartridge presence and the status of the puncture pin mechanism. See Figure 2 -5. O O � O BUCKEYE $RM O 0 ACTUATION LEVER AND PUNCTURE PIN VIEWING WINDOW I I ACTUATION CARTRIDGE VIEWING WINDOW Figure 2 -5.

Systems Releasing Module - SRM -D The Model SRM -D (Systems Releasing Module —Dual) is exactly the same as the Model SRM except that it supports a second independent fusible link detection line. Nitrogen Actuation Cartridges The Kitchen Mister System can use two types of actuation cartridges for system actuation. BPN: BFR -TM Chapter 2 - Components Page 2 - 3 Revision 3 Model BFR -AC -S is a small nitrogen cartridge (included with System Releasing Module) that can actuate up to three (3) agent cylinders.

Model FLB -1, 10" (25 cm) Fusible Link Bracket Assembly Fusible Link Holder The Model FLH Fusible Link Holder is designed to allow for the use of a continuous fusible link line, thus eliminating the need to cut and crimp each individual fusible link. They can be used either with or without fusible link brackets. They are available in packages of 25 (Model FLH -25). See Figure 2 -12. 1116"(0.16 tm) STAINLESS DETECTION CABLE -n -,d Figure 2 -12.

Fusible links are designed to separate at specific temperatures, releasing tension from the fusible link BPN: BFR -TM Chapter 2 — Components Page 2 - 5 Revision 3 detection line and causing system actuation. Correct fusible link selection is an essential element in the design of any restaurant fire suppression system. After performing a temperature study to determine the maximum ambient temperature at the fusible link location, the correct fusible link should be selected from the following chart: Fusible Link Model Number Max. Ambient Temperature FL -280 2250 F. (1070 C.) FL -360 3000 F. (1490 C.) FL-450 3750 F. (1910 C.) FL -500 4300 F. (2210 C.) Figure 2 -13. Globe ML Fusible Link Buckeye Shielded Cable As an alternative to using conduit and corner pulleys to connect the fusible link system, gas valve, and /or remote pull station to the Systems Releasing Module, the Kitchen Mister System utilizes Buckeye Shielded Cable to perform this function. Buckeye Shielded Cable is 1/16" (0.16 cm) stainless steel cable encased in a protective, flexible conduit. See Figure 2 -14. Buckeye Shielded Cable requires no conduit or comer pulleys, as the name implies, provided it is installed in accordance with the guidelines set forth in this manual. Model BFRSC -100 comes with 100 feet (30.5 m) of flexible conduit with 200 feet (61 m) of 1/16" (0.16 cm) stainless steel cable inside it.

See Figure 2 -15. r I Figure 2 -15. Model BFR -SCI, Shielded Cable Interface Note: A 3/32" (0.2 cm) hex wrench is required to tighten the set screw. Compression Type Corner Pulley When Buckeye Shielded Cable IS NOT used to connect the fusible link system, gas valve, and /or remote pull station to the control head, a comer pulley is required whenever a change in stainless steel cable direction is necessary. The Model CPCT -1 corner pulley is equipped with a compression type fitting that connects to standard 1/2" (1.3 cm) EMT conduit. See Figure 2 -16. Figure 2 -16. Model CPCT -1, Compression Type Corner Pulley Discharge Nozzles Misting type discharge nozzles have been specifically developed for appliance, duct, and plenum applications. Each nozzle has a predetermined flow point value and comes equipped with a blow -off cap to protect the end orifice from blockage. Each nozzle is identified by the model number stamped on the nozzle body and has a unique color band for easy visual identification. See Figure 2 -17.

Placement: See Figure 3.7. Aim point: See Figure 3.7. The Model N -1HP nozzle is a one (1) flow point nozzle that can protect a plenum (either single bank or V -bank) of 12 feet (3.7 m) in length and 4 feet (1.2 m) in width per nozzle. Larger plenums must be divided into 12 foot (3.7 m) sections, with each section protected with a separate nozzle. See Figure 3 -7. Plenum: V -bank Nozzle Placement The nozzle must be located at the center of the V -bank width and down 1/3 of the vertical height, within 6 inches (15 cm) of the end of the plenum or plenum module and aimed down the length of the plenum. See Figure 3 -7. Plenum: Single Filter Bank Nozzle Placement The nozzle must be located at a point that is 2" (5.1 cm) from the back edge of the filter and 1/3 of the vertical height of the filter, within 6 inches (15 cm) off the end of the plenum or plenum module and aimed down the length of the plenum. See Figure 3 -7. W 11TW 113N H V BANK 0 1.0 - 15 Figure 3 -7. Model N -1HP Plenum Nozzle Placement and Aiming Note: These examples are typical and do not represent every acceptable nozzle configuration, only a representative sample of them. Designer Note For plenums that exceed 12 feet (3.7 m) in length and therefore require multiple nozzles, it is recommended that the total length be divided into equally sized protection zones and protected accordingly. So a 16 foot (4.9 m) long plenum should be divided into two 8 foot (2.4 m) zones, with a nozzle protecting each, as opposed to a 12 foot (3.7 m) zone and a 4 foot (1.2 m) zone. BPN: BFR -TM Chapter 3 — System Design Page 3 - 3 Revision 3 APPLIANCE PROTECTION Each different appliance must be protected in a specific manner with regard to nozzle selection, placement, and aiming. No deviations from these parameters are allowed and failure to comply completely with these requirements will void the UL Listing of the system and may render the system ineffective. In order to properly understand this section, several key terms need to be defined in advance. DESIGN TERMINOLOGY Nozzle Height: The distance from the tip of the discharge nozzle to the top surface of the appliance (except for woks, in which case the bottom of the wok is used). Hazard Area: All nozzle coverages include the maximum size of the hazard area they can protect. Hazard area is NOT the overall size of the appliance being protected, but rather the actual size of the portion of the appliance used for cooking. Appliances Requiring Multiple Nozzles Some appliances may need to be protected by multiple nozzles because of their size. If the size of an appliance is larger than the approved coverage for that appliance, multiple nozzles must be used. This is accomplished by dividing the hazard area into individual zones that comply with the parameters of the listing for that appliance. In this case, each zone will be protected as an individual appliance with respect to nozzle placement and aiming.
