The Wet Chemical system holds UL listings as a pre-engineered system. Systems shall be designed and implemented according to the following: • NFPA Standard 17A, "Standard for Wet Chemical Systems", • NFPA Standard 96,"Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations", • Other applicable NFPA standards as required for a particular application and design, including, but not limited to, NFPA 70(NEC), and NFPA 72, Fire Alarm Standard. • This Design, Installation, Operation, and Maintenance Manual (DIOM). • Any other standards enforced by a local Authority Having Jurisdiction (AHJ). Configurations in Chapter 3, System Design, are tested and listed to Underwriters Laboratories(UL) Standard 300, 1994 Edition,unless otherwise noted. 1-2 CLASSIFICATION OF FIRE The classification of fire is defined as the following: • Class A: Surface Type Fires; wood or other cellulose-type material(ordinary combustibles) • Class B: Flammable liquids • Class C: Energ 7ed electrical equipment • Class D:Combustible metals(such as magnesium,sodium,zirconium,potassium,and titanium) • Class K: Combustible cooking media(vegetable or animal oils and fats) Note: Range Guard Wet Chemical system is suited for Class K type of fire. 1-3 GENERAL CHARACTERISTICS OF THE BADGER SYSTEM The Range Guard System is a wet chemical fire suppression system with one type of agent. The system is capable of encompassing a wide variety of application requirements. The system utilizes stored pressure agent cylinders. Stored pressure cylinders: • Remain free of contamination • Provide a smooth flow throughout the discharge The cylinders are powder-coated,welded mild-steel shell conforming to DOT specification 4BW/4BA construction and NFPA standards. The valve is forged brass with nickel plating. The plating and cylinder coating makes it corrosion resistant. P/N 9127100 ,.,. 1-1 January 2007 General Information The system can be activated mechanically from manual release, thermo-bulb links,and fusible links. The system can be activated electrically with a 24 Vdc control panel that is tested and listed with the Range Guard system. Both automatic detection and manual release devices are used on control panels. Refer to Paragraph 2-2.1.5 for power requirements. Cylinders are activated from stored high-pressure gas.Automatic and manual actuation are available for the Range Guard System. Other actuations are available, such as: • Mechanical gas valve closure • Dry contacts for annunciation and electrical shutdowns 1-4 SYSTEM DESCRIPTION The Range Guard Wet Chemical System consists of a supply of wet chemical stored in one or more Cylinder and Valve Assemblies. Each cylinder is pressure activated by a System Valve Actuator. The system can be actuated either automatically and/or manually, using mechanical, electrical, or pressure actuation devices. Upon actuation, the wet chemical is discharged through agent distribution piping and specially designed nozzles positioned throughout the protected area. -ay, �' a r --a fm v s as 4 „0& 4.'7. -A' ' r � syem -4-11,7,1‘,„ 3 'x ' � ' g a ah „' .,`z % .M. x a r,,_ _ h...-. ,." .;',.

Included in the kit is the microswitch, pigtail assembly and four mounting screws(two short and two long). Note: Microswitch Kit P/N B120039-501 includes pigtail assembly with white stripes. The wire leads are 24-inches (610 mm)in length.Four Microswitch Kits can be mounted in the UCH Control System. There are two mounting locations to accommodate the four Microswitch kits (two stacked at each mounting location), with EMT ports for each mounting location. This allows for the use of two electrical junction boxes for separation of signal lines and AC lines. These are used when it is necessary to open or close electrical circuits. The following are examples, but not limited to: • Electric appliance shutdown • Make up air shutdown • Electric gas valve shutdown • Shuntbreaker/relay Electrical appliances usually have a higher amp rating than the switches.In this case,such appliances shall not be wired directly to the microswitch.A magnetic contactor or relay must be used.

The Remote Manual Release is attached to the XV Control System or the KRS-50 Control Box,with 1/16-inch control cable.The Remote Manual Release Pull Station is available for use in both the "un-tensioned" Pull-to-Trip and "tensioned" Release-to- Trip lines. To actuate the system at the Remote Manual Release Pull Station, pull out the safety pin and pull hard on the handle. In the Pull-to-Trip mode (XV ONLY), tension will be applied to the cable, allowing the XV Control System to activate the Cylinder and Valve Assembly. In the Release-to-Trip mode, removing the safety pin will release tension from the cable, allowing the XV Control System or KRS-50 Control Box to activate the Cylinder and Valve Assembly. The Remote Manual Release Pull Station may be mounted in a recess or surface mount configuration. The assembly is packaged with all necessary components needed to install in either configuration. Mounting hardware is not included. Each Remote Manual Release Pull Station is supplied with a choice of labels. The proper label must be attached to the faceplate so as to be easily read after installation. Applying the label after installation allows for vertical or horizontal mounting of the Remote Manual Release Pull Station. ii [4.-„,,,,, ,f4,,,Et ii-- , i:,,,,,,,:;,.*,;:„.4,,..,,„_,,,,, ,Il ' PF.e- .tom°i 'i € ' �� 4,T .H-,Z$ Z'Y�8 f 1;40 m �4 4-716 hi. g , ,?

(3 m)or a width of 4 ft(1.2 m). Longer plenums may be similarly protected with a single ADP nozzle being used for each 10 ft. (3.0 m) of plenum length and each 4 ft. (1.2 m) of plenum width. ADP nozzles may be used in combinations(see Figure 3-28). Multiples may be installed facing in the same direction,and/or at the ends of the plenum pointing in. Each nozzle shall provide a maximum of 10 ft. (3 m) of coverage. ADP nozzles must be centrally located in the plenum with their discharge directed along the length of the plenum and located in relation to the filters as shown in Figure 3-28.Refer to Figure 3-28 for filter height.
