It is manufactured by the Amerex Corporation of Trussville, Alabama. Amerex Industrial Systems are a pre-engineered type as defined in NFPA 17- Standard for Dry Chemical Extinguishing Systems. The NFPA 17 definition states pre-engineered systems as "having predetermined flow rates, nozzle pressures, and quantities of dry chemical." It also states that "limitations on hazards that are permitted to be protected by these systems and piping and nozzle configurations are contained in the manufacturer's listed installation and maintenance manual, which is part of the listing of the system." It is essential that all installations, maintenance, and inspections of the Amerex Industrial System be performed in compliance with this manual and NFPA 17. Those individuals responsible for the design, installation, setting into service, maintenance and recharging of the Amerex Industrial Dry Chemical System must be trained by Amerex and hold a current Amerex Certificate. All piping limitations, nozzle coverages, detector placements, etc. have been proven and established through exhaustive teting by Underwriter's Laboratories, Inc.. Use of components other than those referenced in this manual, or installations outside the limitations stated in this manual is unacceptable. U.L. Listing The Amerex Industrial System is an Underwriters Laboratories and ULC Listed pre-engineered extinguishing unit. The system has been evaluated in accordance with U.L. Standard 1254. Tests required for listing under this standard involve fire tests under specific conditions involving a variety of Local Application, Total Flooding, or Screening. Each test fire was allowed to reach its maximum intensity before agent was discharged. Each test was repeated using both maximum and minimum piping, with variations in agent storage. pressure to simulate maximum and minimum temperature ratings. Each test fire was extinguished without splashing of the liquid fuel. Design The system is composed of an agent cylinder I discharge valve charged with Amerex ABC Dry Chemical and either a Mechanical Release Module (MRM) a Pneumatic Release Module (PRM) or an Electrical Release Module (ERM). The quantity of detectors, fusible links, nozzles, corner pulleys, pulley tees and manual pull stations will vary depending on design. The system operates either automatically if actuated by a detector or manually if actuated by a manual pull station. Upon system operation, energy sources for the appliances are shut off immediately. The MRM, PRM and ERM incorporate mechanical and electrical provisions to facilitate the operation of auxilliary devices such as mechanical or electric gas valves and remote audible or visual signal devices. Temoerature Limitations: Local Application, Overhead: 32°F to 120°F (0°C to 49°C) Local Application, Tankside: -20°F to 120°F (-29°C to 49°C) Total Flood: -40°F to 120°F (-40°C to 49°C) Vehicle Paint Spray Booths: -20°F to 120°F (-29°C to 49°C) Open Front Paint Spray Booths: -20°F to 120°F (-29°C to 49°C) UL EX 5208 November, 2007 P/N 15040 General Information Page 1-4 Definition of Terms Actuation Network Copper tubing that allows nitrogen to be supplied from the Mechanical Release Module (or Electrical Release Module) to the Pneumatic Control Head mounted on the Agent Cylinder Valve(s). Agent Cylinder I Discharge Valve Pressurized vessel with the valve assembly containing Amerex dry chemical fire suppression agent and expellant gas (nitrogen). Authority Having Jurisdiction (AHJ) The organization, office or individual responsible for "approving" equipment, an installation or a procedure. The phrase "Authority Having Jurisdiction" is used in NFPA documents in a broad manner• since jurisdiction and approval agencies vary as to their responsibilities.

Piston Plug I Gas Trip A pneumatic device mounted in the MRM (ERM) which upon system actuation, pulls the Cable connected to the Gas Valve causing it to close and stop the flow of gas. UL EX 5208 February 5, 2002 P/N 15040 General Information Page 1-7 Pneumatic Control Head An actuating device bolted to the Agent Cylinder Discharge Valve which receives high pressure nitrogen from the Nitrogen Actuation Cylinder. Pre-Engineered System A system having pre-determined, flow-rates, nozzle pressures and quantities of agent. These systems have the specific pipe size, maximum and minimum pipe lengths, number of fittings and number and type of nozzles prescribed by a testing laboratory. The hazards protected by Pre-Engineered Systems are specifically limited as to type and size by a testing laboratory based on actual fire tests. Limitations on hazards which can be protected by these systems are contained in the manufacturer's installation manual, which is referenced as part of the listing. Pulley Tee A device similar to a Corner Pulley except there is a change in direction on the Cable from two Manual (mechanical) Pull Stations or two Mechanical Gas Valves. It unites either two Gas Valves or two Manual Pull Stations to a single control point. Remote Nitrogen Actuator An assembly designed to operate as a 'slave' actuation device, controlled by the nitrogen cylinder output of either the MRM or ERM. When the Remote Nitrogen Actuator is used, it can operate a total of twenty (20) agent cylinders. Up to two Remote Nitrogen Actuators can be installed on a given system. Series Detector (MRM) Any Detector located between the Mechanical Release Module and the Terminal Detector. Terminal Detector (MRM) The last Detector (or only Detector) in the Detection Network. It is at this point that the Cable for the Detection Network ends or is terminated. Test Link (MRM) This device is used in place of a Fusible Link in order to easily test the Detection Network. The Test Link is easily cut, simulating a Fusible Link separating under fire conditions. It is usually located on the Terminal Detector and is used solely for test purposes.

UL EX 5208 February 5, 2002 (45.2cm) 31 (77cm) - 9 (23cm) 17 13/16 PIN 15040 Component Descriptions Page 2-1 CHAPTER 2 COMPONENT DESCRIPTIONS Agent Cylinder Assembly (Item 1): The agent cylinder is available in three configurations. Models 1S18ABC (PIN 16206), IS35ABC (P/N 16207) , and IS45ABC (PIN 16208) are charged with AMEREX multi- purpose ABC dry chemical agent. The cylinder assemblies are stored pressure designs with an operating pressure of 350 psi (2413 KPa) at 70°F (21°C). The cylinders are constructed of welded steel to DOT 48W 350 specifications. All three models are 9 inches (22.9 cm) in diameter. The discharge valve, which is common to all agent cylinders, is of rugged forged brass construction. The valve is equipped with a 350 psi (2413 KPa) pressure gauge and a fusible element pressure relief plug. The valve controls agent discharge via a spring loaded, internal sealing stem that must be depressed from the top of the valve to initiate agent discharge. The operating temperature of this and other listed system components is -40°F to 120°F (-40°C to 49°C) for Total Flood, -20°F to 120°F (-29°C to 49°C) for Tankside Local Application, Vehicle and Open Front Paint Spray Booths, and 32°F to 120°F (0°C to 49°C) for Overhead Local Application. Warning: Agent cylinders are shipped from the AMEREX factory fully charged with a shipping plate installed on the top of the valve to prevent accidental agent discharge and an anti-recoil plate on the valve outlet to redirect chemical flow should an accidental discharge occur. Both of these plates must be removed at installation. IS18 IS35 and IS45 Dry Chemical Agent (Item 2): For recharging of the Agent Cylinder Assemblies, following a discharge: Amerex multi-purpose ABC Dry Chemical in 45 lb. pails is P/N 09781, (CH 555 Formula 13 Dry Chemical) MSDS and HMIS information on these agents are found in the Appendix Section of this manual. ULEX52O8 February 5, 2002 P/N 15040 Component Descriptions Page 2-2 Agent Cylinder Bracket (Item 3): The agent cylinder bracket is constructed from 1/8 inch (3.2mm) steel & painted to resist corrosion. The part number for this cylinder bracket is P/N 14929. This bracket assembly will accommodate either the lS18 or the taller 1S35145 agent cylinders, and contains two stainless steel straps for securing the cylinder to the bracket .back (use only one strap. for the lS18 cylinder). Agent Cylinder Bracket, Heavy-Duty Wall/Floor Mount: These brackets are constructed of heavier-gauge steel (3/16" and 1/4" with stainless steel strap-retaining hardware). Note that P/N 10180 is used for the lS18, while the P/N 10181 is used for either the 1S35 or the lS45.

P/N 10101 PRESSURE GAUGE, 350 PSI 0671 VALVE STEM 0-RING 10733 -VALVE STEM AS? 16214 COLLAR 0-RING 05239 IS18 = 16212 IS35 AND 1545 16213 ULEX52O8 February 5, 2002 P/N 15040 Component Descriptions Page 2-4 Mechanical Release Module (Item 5): Referred to as the MRM, P/N 11977 is used to actuate the Agent Cylinder Discharge Valve either automatically or manually by puncturing a Nitrogen Cylinder. The pressure from the cylinder pneumatically actuates the Pneumatic Control Head(s), which, in turn, opens the Agent Cylinder Valve(s).. Automatic release of dry chemical agent is accomplished when. a Fusible Link Detector separates under a fire condition and releases tension on the cable. This :causes a spring-loaded plunger to perforate the seal on the Nitrogen Cylinder and releases nitrogen through the Actuation Hose/Piping Network to the Pneumatic Control Head(s) I Discharge Valve(s). Manual release of agent is accomplished by pulling on a Manual Pull Station, which is connected to the Mechanical Release Module by a cable. The Mechanical Release Module is intended for indoor use only, and is equipped with two Microswitch (PIN 12524) for electrical signaling, power shutdown and other auxiliary functions. An additional two Microswitches may be added. Mechanical Release Module II (Item 5): The new MRM II combines the same features and functiohality of the 11977 MRM (see above) along with increased detection capabilities and a far simpler means of setting the detection cable tension. The MRM II is available in the following configurations, now pre-installed in its own enclosure: P/N 18000: MRM II with red-painted steel enclosure P/N 18001: MRM II with stainless steel enclosure The method of setting the detection cable tension on the MRM II does not require the use of any tools (once the cable is locked down into the large, knurled wind-up. spool). A large lever to the right of the spool is used to increase the cable tension. Alignment of the bottom edge of the lever with markings on a label on the mounting plate indicates when the proper tension has been reached. In addition to being easier to set up, lowering cable tension to change out detection links is now also much simpler.

ULEX52O8 November 15, 2007 P/N 15040 Component Descriptions Page 2-8 Recharge Adapter: (Item 12): The Recharge Adapter, PIN 10134 is used as a service tool to open the discharge.valve during agent cylinder recharging. This device is a T- handle design constructed of brass and stainless steel and bolts directly to the top of the agent cylinder discharge valve. The.T-handle is spring loaded and detented to lock in place only in the FULL OPEN or FULL CLOSED positions.. Pneumatic Control Head: (Item 13): This control head (P/N 10147) is necessary in all installations to accomplish either automatic or manual system actuation. This device is constructed of extruded brass and bolts directly to the top of the agent cylinder discharge valve. When supplied with actuation pressure, the piston inside the pneumatic control head extends to depress the stem of the agent cylinder valve releasing the extinguishing agent. Actuation pressure (compressed nitrogen gas) enters the Pneumatic Control Head through 1/4 NPT threaded ports on either side. lOin3 Nitrogen (N2) Cylinder: (Item 14): The 10 in N2 cylinder, PIN 12856, supplies nitrogen gas pressure to the Pneumatic Control Head through the Actuation Network for the purpose of opening the Agent Cylinder Valve.

See Chapter 3B for more details. The cylinder is charged to 1800 psig (12410 KPa) at 70°F (21° C). Pressure is retained in the N2 cylinder by a gold plated rupture disc. Replacement rupture discs are available as PIN 09958. Only genuine AMEREX rupture discs may be used when recharging nitrogen cylinders. Proper charge pressure is indicated by a pressure gauge located on the cylinder bottom and protected by an impact resistant plastic gauge guard. The N2 cylinder is shipped fully charged from the AMEREX factory with a protective shipping cap installed on the outlet threads.

The cylinder is rechargeable by certified AMEREX installers and does not require periodic hydrotesting. MRM I ERM Remote Nitrogen Actuator (RNA): (Item 17): This assembly, P/N 16166, contains an actuation head and a mounting bracket. [The 28 in 3 nitrogen actuation cylinder, p/n 16197 is purchased separately.] The RNA is used when the number of Agent Cylinders in a system exceeds six (MRM systems) or ten (ERM systems). Either one or two RNA's can be used with a single Control Panel. Each Actuator can fire up to 20 Agent Cylinders, branched through a tee, with 10 Agent Cylinders on either side of the tee. Each branch from the tee has a maximum length of 100 feet (21.3 meters) to the last control head. See Chapter 3B for more details. ULEX52O8 February 5, 2002 PIN 15040 Component Descriptions Page 2-10 Mechanical Time Delay - MRM installations: (Item 18): This device (PIN 15765) is used with MRM-equipped systems when a Discharge Time Delay of 15 seconds is required (Refer to UL 1254 Standard for details). It is the first component to connect into the MRM, and is packaged with its own mounting clamp. In the event of system actuation, the Mechanical or Electrical Gas Valves trip immediately, along with any electrical component connected the Microswitch(es), but the high pressure nitrogen actuation gas will be delayed before entering the Actuation Network. The reason for this is to allow for exhaust fan run-down in certain paint spray booth applications. It is not needed for ERM installations, since the ERM can electronically control the time delay function, if required. Vent Check (Item 19): The Vent Check, P/N 10173, is a safety 1 N PT device that installs in the Pneumatic Control Head. Its function is to 4 bleed any slowly accumulating pressure that could cause the Pneumatic Control Head to open the agent cylinder valve prematurely. Examples of possible pressure sources include a slow leak in the rupture disc of an N2 cylinder, or normal temperature-induced expansion of the air and moisture trapped in the actuation network. A. vent check must be used on all pneumatically actuated systems. Use of a pipe plug or other type of "stopper" is unacceptable and can lead --- H to system malfunctions. The body of the vent check is constructed of 16 EX machined brass. The inside of the vent check contains a spring and nylon ball. Slowly accumulating gas can pass around the nylon ball and bleed to the atmosphere. However, the rapid accumulation of actuation pressure from the N2 cylinder causes the ball to compress the spring and seal on a tapered seat, blocking the bleed hole. Following an actuation, the vent check can be used to exhaust residual actuation pressure by unseating the nylon ball (typically with a small piece of wire or the tip of a ball point pen). In installations using multiple agent cylinders, the vent check is installed only in one Pneumatic Control Head at the end of the actuation network. Actuation Tubing (Item 20): The function of the actuation line is to carry high pressure nitrogen gas from the N2 cylinder to the pneumatic control head. Actuation components are installer supplied.

The guidelines listed in this chapter deal with the limitations and parameters of various system configurations. It is the responsibility of the Certified Installer to ensure that the proper system components are being utilized, and that the system meets the limitations and parameters listed in this chapter. Those individuals responsible for the design of the Amerex Industrial Dry Chemical System must be trained by Amerex and hold.a current Amerex Certificate. Amerex will not be responsible for system design, installation, or maintenance performed by any non-certified person(s). ABC Dry Chemical It is necessary for the system designer to consider the combustible material found in the hazard area to ensure proper protection. The agent used in the Amerex Industrial System is suitable for Class A, B, and C hazards. The following are the hazard class definitions: Class - Ordinary solid carbonaceous combustibles. These include wood, paper, cloth, fiberglass, and plastics. Class - Flammable liquids and gases. These include paints, solvents, gasoline, oils, and hydraulic fluids. Class - Electrical appliances. These include computers, power generators, and power transformers. ABC (monoammonium phosphate-based) is suitable for use with all "A", "B", and "C" Class hazards. Dry Chemical Type extinguishing systems are inappropriate for the protection of Class D hazards. As per NFPA 17, pre- engineered dry chemical systems are not approved for deep-seated or burrowing fires (such as ordinary combustibles, where the agent cannot reach the point of combustion), or on chemicals that contain their own oxygen supply (such as cellulose nitrate). Do not mix different types of agents, or agents from different manufacturers. Chemical reactions may. occur when incompatible chemicals are mixed. Keep in mind that the agent used for each system must be acceptable to the Authority Having Jurisdiction (AHJ). Choosing the Proper Type of System It is necessary for the system designer to consider the physical characteristics and layout of the hazard area to ensure proper protection. The system must meet the criteria for a particular hazard and the requirements of NFPA 17 for the system to be effective. Underwriters Laboratories, under the UL 1254 test protocol, has evaluated the Amerex Industrial Dry Chemical System in each of five separate hazard categories. Each category has its own specific installation requirements. It is imperative that the system designer properly identify the fire hazard in order to effectively remain within the UL listing parameters. The remainder of Section 3A is dedicated to matching the Amerex system to each of the five separate hazard coverage categories: 3A.1) Local Application - Overhead - This system is used for applying agent to an area from above the area. Typical applications include dip tanks, power generators, and transformers. The maximum nozzle height for overhead protection is 10 feet. 3A.2) Local Application - Tankside - This system is used for applying agent across a hazard area from the side of the area. Typical applications include, but are not limited to, dip tanks, quench tanks, and solvent tanks where overhead obstructions are present. 3A.3) Total Flooding - This system is used to fill a volume with agent to protect any hazard within that volume. Typical applications include hazardous storage containers and warehouses where sprinkler protection is unavailable. Total flooding systems require a fixed enclosure to be present around the hazard area to allow the system to build up the proper concentration of agent within the hazard area. Whether an enclosure is suitable for allowing total flooding protection depends on the unclosable opening percentage of the enclosure. Unclosable opening percentage is calculated as the area of the opening divided by the total area of the sides, top and bottom of the enclosure. Total flooding protection is qualified for use on hazards whose enclosure has up to 5% UL EX 5208 November 15, 2007 Local Overhead Application, 3A.1, (page 3A-3) Tankside Local Application, 3A.2, (page 3A-5) Total Flooding, 3A.3, (page 3A-7) le V—— 3A-16) Open- Front Paint Spray. Booth, 3A.5, (page 3A-44) UL EX 5208 November 15, 2007 Part Number 15040 System Design Page 3A-2 unclosable opening. For enclosures that have greater than 5% unclosable opening, total flooding protection is not qualified. Use Local Application Overhead for these hazards. 3A.4) Vehicle Paint Spray Booths - This system is selected to protect an enclosed structure that is designed for the purpose of painting vehicles. This structure generally comprises of a work area, separated from a plenum by a filter bank, and an exhaust duct. There are numerous configurations of a vehicle paint spray booth, and all areas (work area, plenum, and exhaust duct) must be simultaneously protected with the coverage from the Amerex system. 3A.5) Open Front Paint Spray Booths - This system is used to protect a paint spray booth with an open front. The booth structure still comprises of a work area, separated from a plenum by a filter bank, and an exhaust duct. The opening at the front of the booth requires special screening of dry chemical to be effective. -Below are Simplified Examples of Each of the Five Hazard Categories: Part Number 15040 System Design Page 3A-3 3A.1 Local Application Overhead: Cylinder: The Model IS45ABC is to be used for Local Overhead Applications. Nozzles: The Local Application Nozzle, (P/N 16216) is used for Local Application, Overhead. The maximum nozzle height is 10 feet. The minimum nozzle height is 8 feet (for fuel in depth splash hazards). The 1S45 cylinder supports four Local Application Nozzles. t,j: Nozzle height is measured from the hazard surface to the closest point of the nozzle in the installed position. Temperature Range: The operating temperature range for the system components used in Local Overhead applications is 32°F to 120°F (0°C to 490C). Piping Requirements: Piping diagrams include limitations on pipe length and fittings. System piping must be balanced. Balanced piping is that in which the difference between the shortest actual pipe length from any 3/4 TEE to nozzle and the longest actual pipe length from any 34" TEE to nozzle does not exceed 10% of the longest-actual pipe length from any 3%" TEE to nozzle. Piping runs from the 1" TEE to each of the 3%" TEE's must be equal in length. The number and type of fittings for all TEE to nozzle sections must be equal. All piping must be Schedule 40, hot-dipped galvanized steel pipe, and all fittings must be 150 lb. class. Examples of acceptable fitting materials include hot-dipped galvanized malleable iron, ductile iron, or steel. Couplings and unions may be used where necessary, and reducing bushings or reducing tees can be used for changes in pipe diameter. Note: Black steel pipe and fittings can be used in relatively noncorrosive atmospheres. -Nozzle Placement and Coverage: The Local Application Overhead Nozzle has been developed to provide local application of extinguishing agent from an overhead position. Each nozzle will protect a hazard area of 27 ft2, with a 6 foot maximum side. -Nozzle Placement for Local Overhead Application UL EX 5208 November 15, 2007 Part Number 15040 System.

UL EX 5208 November 15, 2007 Part Number 15040 System Design Page 3A-1 6 3A.4 Vehicle Paint SDrav Booths (VPSB): The Amerex Vehicle Paint Spray Booth Fire Suppression System is of the pre-engineered type as defined by the NFPA Standard for Dry Chemical Extinguishing Systems, NFPA 17 and the Standard for Spray Application Using Flammable or Combustible Materials, NFPA 33. The extinguishing systems described in this manual are intended to be installed, maintained, and serviced in accordance with NFPA 17 and NFPA 33. The Amerex Vehicle Paint Spray Booth System has been evaluated by Underwriters Laboratories (UL) in accordance with the specific test protocol found in the UL1254 Standard (Pre-engineered Dry Chemical System Units). Used for painting or coating cars, trucks, buses and large mobile equipment, Vehicle Paint Spray Booths come in a variety of configurations and sizes. The basic volumes of a Vehicle Paint Spray Booth to be protected by the Amerex System consists of three main components. They are: Work Area - Where the vehicle is painted. Plenum(s) - Exhaust chambers adjacent to the Work Area. Plenums utilize filters to trap overspray particles that escape from the Work Area. The primary purpose of the plenum is to expose a sufficiently large area of 'filter media to the overspray that is carried along in a smooth current of air. Duct(s) - Fan-powered air channels that draw air through the Work Area, the Plenum(s), and finally out through the Duct. CAUTION: NFPA 33 Standard for Spray Application Using Flammable and Combustible Materials classifies the interior sections of paint spray booths, and certain areas, adjacent to booth openings, as Class-I or Class-11, Division-1 or Division-2 locations. Electrical components of an Industrial Dry Chemical System, such as thermostats located within these areas shall be rated for use in classified areas, and all wiring to these components shall conform to the provisions of NFPA 70, National Electrical Code, for Class —1 or Class-11, Division-1 or Division-2 locations. Any Industrial System Control Head with a Microswitch is not suitable for use in a classified' area. Most of the time, the air is drawn downward over the vehicle during the painting process (as in either an Under Floor, Pit, or Down Draft (Side-Exhaust) configuration). Other booths, such as a Back Draft or Pant-Leg (Horseshoe) design, draw air down and across, toward the rear of the booth. Fresh air is usually drawn in through intake filters either in the Work Area ceiling or on the upper walls of the Work Area. Many installations utilize a Heated Make-Up / Recirculation option, which re-circulates filtered, heated air through the booth, thereby being more energy efficient. The Amerex Vehicle Paint Spray Booth System requires that the booth exhaust fan(s) be shut down prior to the discharge of the ABC dry chemical. This is accomplished with the use of the Mechanical Time Delay (p/n 15765) with mechanically-released systems, or by the use of the Amerex Electric Control Panel (p/n 15780) with the use of the timed discharge circuit. It is the responsibility of the installer to properly identify the configuration of the booth and to follow the requirements of this manual in order to achieve proper fire suppression. Sometimes, additional turns, baffles, or obstructions in the booth's plenum and duct may dictate the use of additional nozzles in order to ensure good distribution of dry chemical.

The IS18 and IS 35 models are used for Duct and Plenum coverage, using either the DP, TF, or 3- Way nozzles. The IS45 model must use two or four TF nozzles (p/n 16172) under Standard Work Area Coverage. The IS45 model uses one or two TFP nozzles (p/n 17809) under Module Perimeter Work Area Coverage. Temperature Range: The operating temperature range for Vehicle Paint Spray Booth applications is -20°F to 120°F (-29°C to 490C). UL EX 5208 November 15, 2007 Part NUmber 15040 System Design Page 3A-17 3A.4 Vehicle Paint SDrav Booths (continued): Piping Requirements: Piping diagrams include limitations on pipe length and fittings. System piping must be balanced. Balanced piping is that in which the difference between the shortest actual pipe length from any 3/4" TEE to nozzle and the longest actual pipe length from any 3,4" TEE to nozzle does not exceed 10% of the longest actual pipe length from any %" TEE to nozzle. Piping runs from the 1" TEE to each of the 3/4" TEE's must be equal in length. The number and type of fittings for all TEE to nozzle sections must be equal. All piping must be Schedule 40, hot-dipped galvanized steel pipe, and all fittings must be 150 lb. class, minimum. Examples of acceptable fitting materials include hot-dipped galvanized malleable iron, ductile iron, or steel. Couplings and unions may be used where necessary, and reducing bushings or reducing tees can be used for changes in pipe diameter. Note: Black steel pipe and fittings can be used, in relatively noncorrosive atmospheres. 3A.4.1 Work Area Coverage, VPSB There are two distinctly different nozzle and piping arrangements for.protecting the Work Area using the IS45ABC cylinder. The first arrangement is "Standard Work Area Coverage", and the second is "Module Perimeter Work Area Coverage' outlined as follows: 3A.4.1.1 Standard Work Area Coverage, VPSB The Amerex Vehicle Paint Spray Booth System is flexible enough to protect a wide variety of Vehicle Booths of various dimensions. The maximum booth height is 23'4". As noted, the IS45 cylinder is used with two or four nozzles, and each of the nozzles has been tested to protect a Work Area Module. A Work Area can be thought of as a series of 'boxes', or Modules, stacked together, each protected with a nozzle. The maximum parameters for each Module are given as follows: Module Volume: 1,050 ft.3 per nozzle, two or four TF nozzles per IS45ABC Maximum Module Area: 105 ft.2 per nozzle for booths up to 10 ft. in height;* 45 ft.2 for booths at 23 ft., 4 in. height.* Maximum Module Height: 23 ft., 4 in. Maximum Module Side Length: Module Center: 14 ft. for booths up to 10 ft. tall* 9 ft for booths at 23'4" tall* Booth Edge: 14 ft for booths up to 10 ft tall Centerline: 15 ft. (widthwise); booth height limited to 10' tall with this option *Note: For Module Center Installations with booth heights between 10' and 23'4", reference table 3A-1 I it Maximum Nozzle Offset -Module Center Entry: Within a 2.5 ft. radius semicircle from center of module, no less than 12" from any side of the module (booth); the curved portion of the semicircle must curve away from the centerline of the booth; the tip of the nozzle within 6" of ceiling. Maximum Nozzle Offset -Booth Edge Entry: Entry-into the module at the closest point to the intersection of the booth wall and ceiling. The nozzle location, horizontally, is at the midpoint of the longest side of the module, +1-2 feet. The tipof the nozzle must be within 6" of its entry point. This option is allowable only for booths 10 feet or less in height. Maximum Nozzle Offset -Booth Centerline Entry: This option is available where nozzle entry is only possible along the centerline of the booth ceiling. Maximum booth height for this option is 10 feet. This installation configuration allows for a maximum module side length of 15', which is the width of the Work Area, in this case. There is no allowable nozzle offset for this option. The first and fourth nozzles are to be located at 12" from the front and back of the booth, respectively. The second and third nozzles are to be spaced equally between the first and fourth nozzles. The tip of the nozzle must be within 6" of the ceiling. UL EX 5208 November 15, 2007 Part Number 15040 System Design Page 3A-18 3A.4.1.1. Standard Work Area Coverage. VPSB (continued) In order to in that the longest side length is not exceeded for each nozzle module, Table 3A-1 must be used to obtain the side length of the module, when one side is known. For example, a work area that is 16 feet in height and 20 feet in width will need four nozzles across the width of the booth. Therefore, 20 divided by 4 = 5 feet. Looking at the 16 feet (height) column, and following it down until the 5 foot length is located, the remaining side length is: 11.75 feet.

The extinguishing systems described in this manual are intended to be installed, maintained, and serviced in accordance with NFPA 17 and NFPA 33. The Amerex Open Front Paint Spray Booth System has been evaluated by Underwriters Laboratories (UL) in accordance with the specific test protocol found in the UL1254 Standard (Pre-engineered Dry Chemical System Units). Although NFPA 33 (Chapter 9) permits Dry Chemical Systems to protect dry powder and electrostatic liquid spray booths under certain criteria Amerex orohibits installation of the IS system in such booths. Open Front Paint Spray Booths come in a variety of dimensions, but only one basic configuration. The basic volumes of an Open Front Paint Spray Booth to be protected by the Amerex System consists of three main components. They are: Work Area - Where the part or equipment is painted with possibly flammable or combustible material (i.e. paints, finishes, lacquers, etc.). The Work Area is open on the front, but enclosed on the sides and top, with a filter bank at the back. Plenum - Exhaust chamber at the rear of the Work Area. Plenums utilize filters to trap overspray particles that escape from the Work Area. Air is drawn in through the front of the booth, across the Work Area, and back through the Plenum. Duct - Fan-powered air channel that draws air through the Work Area, the Plenum, and finally out through the Duct. It is not necessary to shut the exhaust fan down upon system discharge; however, check with the authority having jurisdiction. It is the responsibility of the installer to properly identify the configuration of the booth and to follow the requirements of this manual in order to achieve proper fire suppression. CAUTION: NFPA 33 Standard for Spray Application Using Flammable and Combustible Materials classifies the interior sections of paint spray booths, and certain areas adjacent to booth openings, as Class-I or Class-111, Division-2 Locations, Electrical components of an Industrial Dry Chemical System, such as thermostats located within these areas shall be rated for use in classified areas, and all wiring to these components shall conform to the provisions of NFPA 70, National Electrical Code, for Class —I or Class-11, Division-2 Locations. Any Industrial System Control Head with a Microswitch is not suitable for use in a classified area. Nozzles: Application: TF 16172 Work Area; Plenum SCR 16192 Screening the opening of the Work Area D/P 16190 Exhaust Duct Cylinders: The Model IS18ABC and 1S35ABC are used for Open Front Paint Spray Booth applications in various configurations. Temperature Range: The operating temperature range for Open Front Paint Spray Booth applications is -20°F to 120°F (-29°C to 490C). Piping Requirements: Piping diagrams include limitations on pipe length and fittings. System piping must be balanced. Balanced piping is that in which the difference between the shortest actual pipe length from any 3/4) TEE to nozzle and the longest actual pipe length from any 34" TEE to nozzle does not exceed 10% of the longest actual pipe length from any %" TEE to nozzle. Piping runs from the 1" TEE to each of the 34" TEE's must be equal in length. The number and type of fittings for all TEE to nozzle sections must be equal. UL EX 5208 November 15, 2007 Part Number 15040 System Design Page 3A-45 3A.5 Open Front Paint Spray Booths (OFPSB) (Continued) All piping must be Schedule 40, hot-dipped galvanized steel pipe, and all fittings must be 150 lb. class, minimum. Examples of acceptable fitting materials include hot-dipped galvanized malleable iron, ductile iron, or steel. Couplings and unions may be used where necessary, and reducing bushings or reducing tees can be used for changes in pipe diameter. Note: Black steel pipe and fittings can be used in relatively noncorrosive atmospheres. 3A.5,.1 Open Front Paint Spray Booths (OFPSB) Nozzle Coveraes Work Area and Plenums: The Amerex Industrial System is flexible enough to protect a wide variety of Open Front Booth dimensions.

Detection Network, MRM Installations: Optimum Fire Suppression System performance depends on proper Detection Network design. This section discusses the type of Detectors used, their selection, placement and design limitations. The Amerex Industrial Fire Suppression System uses a continuous cable, Corner Pulleys, Detector Bracket, Detector Linkage, Fusible Links, Conduit Offset, and a Terminal Link Connector for the Detection Network. The quantity of detectors to be used in an MRM system will depend on the ceiling area and height. Fusible Links of the metal-alloy type (p/n's 12326,12327, 12328, and 12329) can be spaced every 10 feet for smooth ceilings up to 12 feet high. The Job Quick Response Links (p/n 16225, 16226, and 16227) can be spaced every 20 feet for smooth ceilings up to 12 feet high. A detector is required at the interface of the duct and plenum, as well as downstream of any obstruction (such as a damper) or ignition source (such as a fan). Consult NFPA 72 for reductions in spacing for ceiling heights in excess of 12 feet, and for spacing guidelines when different arrangements are encountered. Note: Standard Response Fusible Links are NOT recommended for use in Paint Spray Booths because of their slow reaction time. For this reason, Amerex recommends either the Job Quick Response Links, or the Electric Thermal Detectors (see section on ERM Detection Networks). However, Standard Response Fusible Links may be used if permitted by the authority having jurisdiction. Fusible Link Detectors are required in all hazard areas protected by the Amerex Industrial Fire Suppression Systems for automatic system operation. The adaptation of Fusible Links to the Mechanical Release Module is described in Chapter 4. A temperature survey must be performed to determine the maximum ambient temperature of the hazard survey. The selection of the Fusible Links should be made according to the temperature measured: Temperature Measured Link Rated Temperature Fusible Link Part Number 700 to 150°F (21° to 65°C) 212°F(00°C) 12326 151° to 225°F (660 to 107°C) 280°F (138°C) 12327 2260 to 300°F (1080 to 149°C) 360°F (182°C) 12328 3010 to 375°F (1500 to 191°C) 450°F (232°C) 12329 376°F (192° C) and above Consult Factory Consult Factory Temperature Measured Link Rated Temperature Job Link Part Number 700 to 150°F (21° to 65°C) 200°F (93°C) Quick Response 16225 1510 to 225°F (660 to 107°C) 286°F (141°C) Quick Response 16226 2260 to 300°F (1080 to 149°C) 360°F (182°C) Quick Response 16227 General Limitations of Detection Network: Maximum of 30 Corner Pulleys, P/N 12309.

Detection Network, ERM Installations: The Electrical Release Module (ERM) uses four-wire, rate of rise Thermal Detectors as the system initiating device. The advantages over fusible link systems are that the reponse time is faster, and the device is resettable. Refer to Design and Installation Manual, pin 15827, for more info?mation on the ERM. CAUTION: It is likely that industrial applications involving FLAMMABLE or COMBUSTIBLE liquids will be enclosed within or surrounded by areas that will be classified as CLASS I or CLASS II, DIVISION I or DIVISION 2 locations. Dry chemical system electrical components, such as thermostats, located within these areas shall be rated for use in classified areas, and all wiring to these components shall conform to the provisions of NFPA 70, National Electrical Code, for CLASS I or CLASS II, DIVISION I or 2 locations. Any industrial system Control Head with a microswitch is not suitable for use in a classified area. In order to minimize delays in thermostat response, it is imperative that a temperature survey be performed at all locations where thermostats will be installed. The survey must be conducted under maximum operating conditions to determine the peak temperatures that are expected to be reached. Readings should taken with and without airflow. Once this information is established, select a detector with a setpoint between approximately 75 and 100°F HIGHER than the maximum expected temperature for that particular mounting location. 'The probe of the detector should be mounted so that it will be exposed to escaping hot gases, in the event of a fire.

Refer to the Design and Installation Manual, p/n 15827, for more information. ULEX52O8 February 5, 2002 Part Number 15040 System Design Page 3B-4 5. a) Actuation Network Limitations, MRM Installations: The Actuation Network for the Amerex Industrial Fire Suppression System consists of installer -supplied copper tubing that connects the MRM to each PneumaticControl Head on top of each cylinder discharge valve. A single MRM is capable of actuating up to 6 Agent Cylinder Discharge Valves by discharging a single 10 in nitrogen cylinder (PIN 12856) through the actuation network. The maximum length of copper tubing is 100 feet. If a 15 second discharge delay is required (such as with a Vehicle Paint Spray Booth), the Mechanical Time Delay (P/N. 15765) must be used. Refer to Chapter 4 for installation instructions of the Mechanical Time Delay. Note A single vert check (P/N 10173) must be used on the last Pneumatic Control Head on the last Agent Cylinder. It is designed to release any slowly built up pressure from the actuation lines. This device should be accessible for pressure bleed-off after system discharge. P/N 10173 Vent Check Limitations (Single or Multiple Cylinder Systems): Temperature Limitations for Nitrogen Actuation Cylinders: -20°F to 120°F (-29°C to 49°C) Copper Tubing: 14" O.D. Refrigeration Type, with a minimum .049" wall thickness (meeting ASTM B251 and B75). Use with brass or steel SAE 45° Flared Tube fittings.' Maximum Total Length (including all fittings, from Mechanical Release Module to last Pneumatic Control Head) = 100 feet (30.48 meters). Vent Check p/n 10173 ULEXS2O8 February 5, 2002 Vent Check, p/n 10173 ERM Part Number 15040 System Design Page 3B-5 5. b) Actuation Network Limitations, ERM Installations: The Actuation Network for the Amerex Industrial Fire Suppression System consists of installer supplied copper tubing that connects the ERM to each cylinder discharge valve. A single ERM is capable of actuating up to 10 Agent Cylinder Discharge Valves by discharging a single 15 in nitrogen cylinder (PIN 09956) through the actuation network. The maximum length of copper tubing is 100 feet. If a 15 second discharge delay is required, the ERM is capable of being programmed internally for the discharge delay. Refer to Design and Installation Manual, pin 15827, for more information on the ERM. Note: A single vent check (PIN 10173) must be used on the last Pneumatic Control Head on the last Agent Cylinder. It is designed-to release any slowly built up pressure from the actuation lines. This device should be accessible for pressure bleed-off after system discharge. P/N 10173 Vent Check Limitations (Single or Multiple Cylinder Systems): Temperature Limitations for Nitrogen Actuation Cylinders: -20°Fto 120°F (-29°C to 49°C) Copper Tubing: I/i" O.D.

ULEX52O8 February 5, 2002 100 FEET MA 10173 Vent Check Part Number 15040 System Design Page 3B-6 5. c) Remote Nitrogen Actuation (RNA) Network Limitations: The Remote Nitrogen Actuator, p/n 16197, is a device used in conjunction with either the MRM or the ERM when the number of Agent Cylinders required exceeds the maximum number supported by the Control Panel. When an RNA is used, the high pressure gas from the MRM or ERM is used to fire the RNA, which, in turn, fires the Pneumatic Actuators attached to the Agent Cylinders. A total of 200 feet of copper tubing is allowed when tee'd from the outlet of the RNA; the longest distance allowed from the RNA to the last Pneumatic Control Head is 100 feet. Each 100 foot long section of tubing can support ten (10) Pneumatic Control Heads. Therefore, each RNA can support 20 Agent Cylinders. See the following illustration for RNA limitations. Note: A Vent Check (P/N 10173) must be used on the last Pneumatic Control Head on the last Agent Cylinder of one of the tubing branches from the RNA. The last Pneumatic Control Head on the opposite branch must be plugged with a high pressure 14" NPT pipe plug. Also, a Vent Check is required at the pressure inlet of the RNA (where the copper tubing from the control panel enters the RNA). If there are more than one RNA's installed, only one vent check is required on the control pahel-to-RNA network. Use a high pressure 1/4' male branch tee at the RNA to install the Vent Check. The Vent Check is designed to release any slowly built up pressure from the actuation lines. This device should be accessible for pressure bleed-off after system discharge.

Each Remote Nitrogen Actuator (P/N 16197) is capable of firing up to twenty (20) Agent Cylinders; two Remote Nitrogen Actuators could therefore fire a maximum of forty (40) Agent Cylinders when used with one MRM. All Agent Cylinders are fired by the Remote Nitrogen Actuator(s), when used, and the nitrogen cylinder in the control panel is dedicated only to firing the Remote Actuator(s).

Each Remote Nitrogen Actuator (PIN 16197) is capable of firing up to twenty (20) Agent Cylinders; four Remote Nitrogen Actuators could therefore fire a maximum of eighty (80) Agent Cylinders when used with the ERM. All Agent Cylinders are fired by the Remote Nitrogen Actuator(s), when used, and the nitrogen cylinder in the control panel is dedicated only to firing the Remote Actuators. Note: A Vent Check (PIN 10173) must be used on the last Pneumatic Control Head on the last Agent Cylinder of one of the tubing branches from the RNA. The last Pneumatic Control Head on the opposite branch must be plugged with a high pressure 1fl' NPT pipe plug. Also, a Vent Check is required at the pressure inlet of the RNA (where the copper tubing from the control panel enters the RNA). If there are more than one RNA's installed, only one vent check is required on the control panel-to-RNA network. Use a high pressure 14" male branch tee at the RNA to install the Vent Check.

For example, if a system using four RNA's uses 60 feet of tubing from the ERM to the 1st RNA (on the 1St TEE'd branch) then the length of tubing from the ERM to the 2 n RNA cannot be less than 30 feet. Likewise, the length of tubing from the ERM to the 3rd RNA cannot be less than 30 feet, also.

Mechanical Gas Valve Applications (MRM or ERM): Both the MRM and the ERM close the Mechanical Gas Valve immediately upon system discharge. A pneumatic and mechanical action in the Module pulls on a cable attached to the mechanical gas valve, unlatching the valve and allowing an internal spring within the valve body to provide the closing force. Connection of the cable from the valve to the MRM under tension maintains gas valve in an open position. Mechanical Gas Valve: A Mechanical Gas Valve Trip Cylinder assembly must be used with any mechanical gas valve. The gas valve trip cylinder assembly (PIN 12740) is included with all Amerex manufactured gas valves, but may be ordered separately for use with gas valves listed in this manual supplied by other manufacturers. AMEREX PART NO. 12740 See Chapter 1 "System Components" for all mechanical gas valves that are suitable for use with the Amerex Industrial Dry Chemical System. The use of any other mechanical gas valves will void the U.L Listing for the system installation. All of the listed valves have female NPT threads. The location of the gas valve should be accessible and approved by the Local Authority Having Jurisdiction. Installation should be performed by a contractor licensed and qualified for such work. Mechanical Gas Valve Actuation Network Limitations: The Mechanical Gas Valve Actuation Network consists of Cable, Corner Pulleys, Pulley Tee, Gas Valve and Conduit Offset. General Limitations of Mechanical Gas Valve Network: Maximum of 20 Corner Pulleys (P/N 12309) per Mechanical Gas Valve Maximum of 130 feet of Cable (PIN 12553) per Mechanical Gas Valve Maximum of I Pulley Tee (P/N 12506) per network (counts as one Corner Pulley for each Mechanical Gas Valve) Maximum of 1 Conduit Offset (PIN 12507) per network (must be located at MRM (or ERM) and before Pulley Tee when chosen) ii CONDUIT OFFSET (OPTIONAL) MRM or ERM UPXU I CABLE LE QUANTIT' AS IRK SINGLE GAS VALVE NETWORK ULEX52O8 February 5, 2002 Part Number 15040 System Design Page 3B-1 I - 7. Electrical Gas Valve Operation: 110 VAC Electrical Gas Valves may be used in place of the Mechanical Gas Valves. The Electrical Shut-Off Valve used with the Amerex Industrial Dry Chemical System must be U.L. Listed for use with natural gas or propane, be held open by energizing an electrical solenoid and be wired through a microswitch and manual reset relay. Any field wiring and connections involving the shutdown of electrical equipment or an electrical gas valve must be done by a qualified electrician. Power to the Electrical Gas Valve is run through the normally closed contact on a microswitch located in either the MRM or ERM to the Manual Reset Relay and from the Manual Reset Relay to the Electrical Gas Valve. In a normal, non-fire condition, current is allowed to flow to the solenoid on the Electrical Gas Valve, holding the valve open. In a fire condition, when the suppression system actuates, the microswitch contacts will transfer, opening the normally closed contacts in the Manual Reset Relay,. interrupting the current to the gas valve and cause it to close. Resetting the MRM (or ERM) and transferring the contacts back to a normal (normally closed) position will not cause the Electrical Gas Valve to open. The Manual Reset Relay must be reset before current will flow to the valve and cause it to open. A loss in electrical power, even temporary, will require someone to manually reset the relay before the Electrical Gas Valve will open again. Note: see wiring schematics on the following page. MICROSWITCH APPLICATIONS: The PIN 12524 Microswitch is installed in the Mechanical Release Module and Electrical Release Module. Up to three additional P/N 12524 switches may be added to the MRM, and two additional switches may be added to the ERM. WMM700~~~ RED: COMMON YELLOW: N.O. BLACK: N.C.

Dual MRM Installations Protecting aSingle Hazard: Certain circumstances may require additional link line capability, detectors, or manual pull stations to protect a single hazard. Examples would include multiple fire hazards in close proximity to one another (or interconnected) or large paint spray booths. It is possible to install two MRM's to protect such hazards as a single hazard zone.

Use only two Check Valves, oriented at the Tee, as shown. The purpose of the Check Valves is to prevent one MRM from back-pressurizing the MRM that does not trip. Limitations: Adhere to the MRM actuation limitations as given on pages 313-4, 6 and 7. The maximum length of tubing from the MRM, either to the last Agent Cylinder, or to the RNA(s), is determined as the direct single path from each MRM through the Tee. If the discharge time delay function is required, then two Mechanical time Delays must be used, one adjacent to each MRM, and installed in accordance with the Installation section of this manual. Detection Networks are to remain independent from MRM #1 to MRM #2, and must adhere to previously stated limitations. Manual Pull Networks are to remain independent from MRM #1 to MRM #2, and must adhere to previously stated limitations. There is no Mechanical Gas Valve function with this installation option. ULEX52O8 February 5, 2002 Part Number 15040 System Design Page 313-14 Any electrical function must be wired in either series (Normally-Closed function) or in parallel (Normally-Open function) through a .microswitch in each MRM. This will ensure that the firing of either MRM will facilitate the required function. A clearly visible sign or placard must be placed securely adjacent to each of the-two MRMs with the wording similar to the following: "This Releasing Control Head is One of Two Units. Both Units Must be Seviced Together, in Conjunction with the Fire Suppression System". An audible device must be used with this system configuration, wired through microswitches of each MRM's, so that the firing of either MRM will provide an audible signal. Warning: All Electrical Field Wiring Should be Performed by a Licensed Electrician per NFPA 70. 9. Explosion Proof Pressure Switch: Amerex P/N 16384 Explosion Proof Pressure Switch is used in hazardous locations, where standard electrical microswitches are prohibited. It is designed to be installed in the distribution piping of any of the system's agent cylinders. It must be installed within 12" of the Agent Cylinder Valve outlet with an inline tee. Place the switch on a 12" vertical section of 1/2' pipe, in order to separate it from the flow of dry chemical, as shown below: PRESSURE WITCH DIPE Note: The 12" section of vertical 1/2" pipe counts as one foot of pipe from cylinder .to TI when tabulating pipe lengths. Also, the Tee counts as one elbow from cylinder to Ti. The pressure setting is not field-adjustable. Warning: All Electrical Field Wiring Should be Performed by a Licensed Electrician per NFPA 70. ULEX52O8 February 5, 2002 Part Number 15040 System Installation Page 4-1 CHAPTER 4 SYSTEM INSTALLATION A) General Those individuals responsible for the installation of the Amerex Industrial Dry Chemical System must be trained by Amerex and hold a current Amerex Certificate. Before starting the installation of a system, a complete analysis of the hazards, a system design and a drawing of the proposed system layout should be accomplished. The design, drawings, and bill of materials shall be compared with conditions found at the jobsite and discrepancies noted before proceeding. Materials such as pipe, fittings, copper tubing, EMT conduit, fasteners, mounting and securing hardware for pipe and conduit are not supplied by Amerex with the Industrial Fire Suppression System. These items are chosen and supplied by the installer. All components must be installed in an environment that does not exceed the system's temperature range listing of -40°F to 120°F (-40°C to 49°C) for Total Flood, 32°F to 120°F (0°C to 49°C) for Local Application Overhead, and —20°F to 120°F (-29°C to 49°C) for Local Application Tankside, Vehicle Paint Spray Booth and Open Front Booth installations. All system components - Release Module, Cylinder Assembly, Mounting Brackets, Detectors, Fusible Links, Agent, Nozzles, Manual Pull Stations, Gas Shut Off devices, Corner Pulleys, Pulley Tee, Nitrogen Cylinders, etc. must be U.L. Listed for use with the Amerex Industrial Fire Suppression System. Only those components outlined by part number in this manual have been evaluated for use with the Amerex Industrial Dry Chemical System. The use of non-Amerex parts or components may void the manufacturer's warranty. B) Installing the Agent Cylinder Bracket Choose an appropriate location for the Agent Cylinder Bracket and valve assembly where the pressure gauge can be read and the cylinder accessible for recharge and service. Also, it is important that the location be acceptable to the Authority Having Jurisdiction (AHJ). The agent cylinder bracket must be secured to a structure that is sufficient to accept the weight. Using the bracket back as a template, mark the top hole, secure the bracket loosely with the appropriate fastener, adjust for level and plumb, mark the remaining holes and fasten securely. 16 (489 .43 cm) holes (4) EX 5208 February 5, 2002 EX 5208 February 5, 2002 Part Number 15040 System Installation Page 4-2 Warning: Agent cylinders are shipped from the AMEREX factory fully charged with a shipping plate installed on the top of the valve to prevent accidental agent discharge and an anti-recoil plate on the valve outlet to redirect chemical flow should an accidental discharge occur: Both of these plates must be removed at installation. C)1) Installing the Mechanical Release Module (MRM) Select a suitable location for the Mechanical Release Module that allows-access for installation, service, recharge and where both the Nitrogen Actuation Cylinder pressure gauge and system status indicator can be viewed. The MRM must be fastened to a surface Which has sufficient structure to support the loads anticipated. Knockouts are provided on three sides of the two available enclosures (painted or stainless steel) and each cable run may enter the enclosure from any of the three sides (top, bottom or right). Using the enclosure as a template, mark the top• two holes for mounting and anchor the enclosure loosely, adjust to level and mark bottom holes, anchor securely using appropriate fasteners. Once the enclosure is firmly attached to the mounting surface, the MRM "motherboard" can be installed into the enclosure stand-offs using the four machine screws provided with the MRM. Do not install the Nitrogen Cylinder at this time.

The network originates at the pipe outlet of the MRM (or ERM) and continues to each Pneumatic Control Head (P/N 15157) mounted to the top of each Agent Cylinder Valve assembly. The protective plug at the port on the MRM must be removed. If the Pneumatic Time Delay (p/n 15765) is required on MRM installations, it must be installed adjacent to the MRM, connected directly into the outlet port of the MRM (see figures on the following page). All threaded connections in the Actuation Network must be sealed with Teflon tape (applied to male threads only). Starting with the second thread from the fitting opening, wrap the tape clockwise around the threads away from the fitting opening. Make certain that tape does not extend past the end of the fitting. Below is the outlet port (1/4" NPT) of the MRM. Note: Only one Vent check (P/N 10173) is required for an Actuation Network (without RNA's). It must be placed on the last 1/4" NPT port of the last Pneumatic Control Head (PIN 15157) in the Actuation Network.

MECHANICAL TIM DELAY E) Installing the Distribution Piping Network For limitations on the Distribution Piping Network, refer to Chapter 3, System Design. All piping must be Schedule 40, hot-dipped galvanized steel pipe, and all fittings must be 150 lb. class. Examples of acceptable fitting materials include hot-dipped galvanized malleable iron, ductile iron, or steel. Couplings and unions may be used where necessary, and reducing bushings or reducing tees can be used for changes in pipe diameter. Note: Black steel pipe and fittings can be used in relatively noncorrosive atmospheres. All pipe must be reamed and blown clear. Dirt and/or cutting oil must be removed from the inside of all pipe and fittings before assembly. Assemble all pipe and fillings tight - 3 turns past hand-tight is recommended. The use of Teflon tape, joint sealant, or pipe compound is not necessary on the Distribution Piping Network and must not be used. -' Secure all piping to a rigid surface using appropriate hangers and/or clamps in accordance with accepted plumbing techniques. Once Discharge nozzles are installed, ensure that the plastic blow-off caps are in place. EX 5208 S February 5, 2002 Part Number 15040 System Installation Page 4-5 The flow of the mixture of dry chemical and gas does not strictly follow general hydraulic principles because it is a two-phase flow. Changes in direction of flow cause separation of expellant gas and dry chemical. To provide proper distribution of dry chemical upon splitting the stream, special attention must be given to the method in which an approach is made to a tee after a change in direction. Certain acceptable methods are shown below, which are taken from NFPA 17, the Standard for Dry Chemical Extinguishing Systems: NOT LESS THAN 20 PIPE DIAMETERS F)1) Installing the Detection Network -MRM Installations Refer to Chapter 3, System Design, for limitations on Detection Networks. There is only one type of detector bracket and linkage used with this system. There are, however, two different names for detectors in the network - Series and Terminal. The Terminal Detector is the detector located at the end of the cable run, furthest away from the MRM. A Series Detector is any detector located between the MRM and the Terminal Detector in the network. Starting at any of three sides (top, bottom, or right) of the MRM at the corresponding knock-out, install h/2 EMT conduit running from the MRM to each detector location, using a corner pulley at every change in direction. Each detector must be securely fastened to a rigid surface. POSITION LINK HOLDER AND LINK IN CENTER (OR SLIGHTLY OFT CENTER AWAY FROM MRM) IN BRACKET. To install the cable, start at the Terminal Detector, affix the cable with a Terminal Clamp (PIN 12859), provided with the MRM) leaving a minimum of 6 inches between the end of the cable and the terminal clamp. From the Terminal Detector, continue to feed the cable through each Corner Pulley, detector, and length of EMT conduit back to the MRM. To install the .detector linkage, place a weighted object on the cable at the MRM, allowing a minimum of 3 inches of slack for every detector in the network. Starting at the Terminal Detector, place the linkage upside down on the cable, run the cable over the rivet and through each of the four tabs as shown above, insert the appropriate Fusible Link (see the design section for the proper selection of Fusible Links) and turn upright. Repeat these steps for each detector. EX 5208 February 5, 2002 Part Number 15040 System Installation Page 4-6 Each link and link holder, once assembled and placed on the cable, should be positioned in the bracket on center or slightly off center away from the MRM. Setting Detection Cable Tension, Original MRM ON 11977): To set the tension on thecable, first make sure that the tension bar in the MRM is in the "down" position and that the spring is relaxed. Caution: Do not attempt to set the tension bar in the "up" position (spring stretched) without having a fusible link line installed and secured or the MRM will fire. Take additional caution; DO NOT install the Nitrogen Actuation Cylinder at this time. Attach the cable to the link plate connector. Do not clamp tightly (slack must be taken up in 'a later step). Insert the connector into the slot on the link plate that corresponds with the direction of pull on the cable. The link plate is marked with clock positions (6:00, and 12:00). Insert the connector at 12:00 if the cable enters the MRM at the TOP and 6:00 if it enters at the BOTTOM. Note: any excess cable must be secured out of the way of any parts in the MRM. We suggest taping it back to the link cable. Slip the Set-up/Lock-out Tool,(P!N 12738)'over the manual pull cam housing until it rests against the outside edge of the link plate. ULEX52O8 April 1'512008 P/N 15040 System Installation Page 4-7 Draw tension on to the cable through the connector until the link plate is drawn against the set-up tool, then tighten the set screw on the connector. Remove the set-up tool and raise the tension bar to test cable run. Lower tension bar until system is ready to test. To test the Detection Network, refer to Chapter 5, Setting the System into Service. SettinQ Detection Cable Tension, New MRM IL.(PIN 18000 and 18001): Refer to the following images in this section for properly setting the detection cable tension: To set the tension on the cable, first make sure that the tension bar in the MRM is in the "down" position and that the spring is relaxed. Lower the top hook of the blue spring into the bottom of the tension bar slot. Caution: Do not attempt to set the tension bar in the "up" position (spring stretched) without having a fusible link line installed and secured or the MRM will fire. Take additional caution; DO NOT install the Nitrogen Actuation Cylinder at this time. Feed the cable end into the small hole in the side of the ratchet pulley. The end of the cable must be cleanly cut. Push the cable into the hole until the end is visible at the head of the central hex-bolt. Securely tighten the Allen- head set screw onto the cable. Aside from the use of the cocking tool, no further tools should be used to set the mechanism. [The cable may be routed from either the bottom or the top of the MRM II; the ratchet pulley will always turn counter-clockwise to remove cable slack]. Spool up the excess cable slack by turning the ratchet pulley counter-clockwise by hand. Continue to hold the ratchet pulley while proceeding to the next step. While maintaining the position of the ratchet pulley with your left hand, press down on the engagement pawl and the linkage bar with your index and middle fingers of your right hand in order to begin the final tensioning process. You will feel and hear the pawl click several times as tension is taken up Inspect your progress by pulling the upper hook of the blue spring into the top notch of the tension bar; then raise the tension bar. Refer to the illustrations on the following page for proper setting. Repeat steps 1-5 until the bottom of the linkage bar is essentially horizontal, and is aligned within the gray "pie" zone of the indicator label (see Figure B). Lower tension bar until system is ready to test. To test the Detection Network, refer to Chapter 5, Setting the System into Service.

Recharge Procedures Warning: Before attempting any recharge procedures, first confirm the reason for the discharge. The Amerex Industrial Fire Suppression System must be recharged immediately after any discharge regardless of the cause of the discharge. If recharge cannot be accomplished immediately - Do not leave the system incapacitated for any reason without giving written notification to the owner, owner's agent, local AHJ, and documenting the incident in the permanent job file. Clean up: Following a system discharge, IMMEDIATELY CLEAN ALL SURFACES contacted with ABC dry chemical to avoid corrosion. If the dry chemical has not been heated and is dry, it may be swept, vacuumed, or blown from any surface it has contacted. If it has been wetted or come in contact with heat, scrubbing, power washing with a soap solution, or steam cleaning may be necessary. The dry chemical is slightly corrosive to metals after being wetted similar to a mild* salt water solution. Caution: The dry chemical extinguishing agent is completely non-toxic in all forms. However, it is classified as a "Nuisance Dust" irritant, and may cause temporary irritation to the eyes, skin, or respiratory system. A complete MSDS sheet is available upon request, or can be found either in the Appendix, or on the Amerex website. Recharging Agent Cylinders Relieve all pressure in the actuation line by depressing the nylon ball in the Vent Check. Unbolt the Pneumatic Control Head from the Agent Cylinder Discharge Valve. The piston of the control head will be locked in the "fired" position, and it must be reset. To reset the control head, use a small flat tool to depress the small plunger ball on the side of the extended brass piston while simultaneously pushing the piston back into the head. Do not attempt to unscrew the small plunger from the brass piston. The piston should be pushed back into the fully retracted position while depressing the plunger ball.

Properly dispose of any chemical that is contaminated or caked. Inspect the interior of the cylinder for residue (clean if necessary). Inspect cylinder threads and 0-ring seat for evidence of damage. 6. Disassemble the valve by removing the return spring retaining screw (use a 1/8" Allen hex wrench), spring retaining washer, return spring, valve stem and downtube. Do not remove gauge or fusible plug- unless replacement is necessary. Thoroughly clean all parts with a soft bristle brush or soft cloth. Blow out the valve and downtube (and air valve if used to depressurize cylinder) with air or nitrogen. Inspect the collar 0-ring, valve stem, and other hardware - replace parts only with Amerex factory replacemants if worn or damaged. Part Number 15040 Reset and Recharge Page 7-6 Inspect sealing area in valve body. Discard valve body if seat is damaged. Lubricate the collar 0-ring and small 0-ring on the valve stem with Visilox V-711 (do not lubricate the valve seat oring). Reassemble the valve. Service the Agent Cylinders. Clean cylinder to remove dirt, grease or foreign material. Check to make sure that the instruction nameplate is securely fastened and legible. Inspect the cylinder for corrosion, abrasion, dents or weld damage. If any of these conditions are found and you doubt the integrity of the cylinder, hydrostatically test to factory test pressure (700 psi, 4827 kPa), using the proof pressure method, in accordance with CGA Pamphlet C-6 and NFPA 17. Inspect the Agent Cylinder interior following CGA Visual Inspection Standard, Pamphlet C-6. Fill Agent Cylinder with the proper amount of only Amerex Formula 13 ABC (P/N 09781; CH 555) by weight as specified on the Agent Cylinder nameplate. The fill tolerances for the 18 lb., 35 lb., and the 45 lb. Agent Cylinders are: +0.1 lb., -0.0 lb. WARNING: Use only fresh, free flowing dry chemical. WARNING: Filling by eye alone could cause potentially dangerous overfilling - always use a scale. WARNING: If Agent Cylinder is hydrostatically retested, thoroughly dry interior-of cylinder prior to adding chemical. Clean Agent Cylinder collar 0-ring seating surface and threads with a small brush, then wipe surfaces with a clean damp cloth to remove dust. Lightly brush the 0-ring seat with Visolox V-71 1. Install discharge valve assembly and tighten using a 21/2" open-end, thin head wrench. HINT: Tapping on the side of the cylinder with a rubber mallet as the downtube is inserted will aid in assembly. Warning: Always completely depressurize extinguisher before attempting to recharge. Never have any part of your body over the extinguisher while removing the valve assembly. Always use a proteótive shield between you and the pressure gauge while charging an extinguisher. Do not stand in front of the gauge if a shield is not available. Always use a REGULATED pressurizing source of dry nitrogen only with a minimum dew point of minus 70°F (minus 57°C). Set the regulator to no more than 400 psi (2758 kPa). Check and calibrate regulator gauge at frequent intervals. The regulator gauge should be used to determine when the intended charging pressure has been reached. Do not rely on the extinguisher gauge for this purpose. Never leave an extinguisher connected to a regulator of a high pressure source for an extended period of time. A defective regulator could cause the cylinder to rupture due to excessive pressure. Do not mix types of dry chemicals in extinguishers, recharge or recovery systems. Mixing ABC (acidic base) with Regular, Purple K, Super K, or Monnex (alkaline base) dry chemicals may result in a chemical reaction capable of developing dangerous pressure buildup. EX5208 February 5, 2002 Part Number 15040 Reset and Recharge Page 7-7 Pressurize the Agent Cylinder: Attach a pressurizing adapter to the discharge port (1' NPT thread; construct a fitting from a 1" to 1A" pipe reducing bushing and a "quick-connect" air fitting) and a PIN 10134 Recharge Adapter to the top of the valve. Connect the adapter to a regulated nitrogen supply. Rotate the recharge adapter lever to "open" position and pressurize the cylinder to 350 psi (at 700F). When the desired pressure has been reached, rotate the operating lever to the "closd" position. Shut off nitrogen supply and disconnect the supply line. Remove the pressurizing adapter and the control head. NOTE: Pressurizing the cylinder in this manner will allow for proper aeration of the chemical through the downtube. 10134 RECHARGE 1=-ADAPTER Check the agent cyli.nder for leaks: Apply leak detect fluid (soapy water) to the collar seal, discharge outlet, fusible plug threads, gauge threads, and cylinder welds. Look for bubbles in the leak detect fluid. Bubbles may take several minutes to appear. Blow dry all areas contacted by leak detect fluid when complete. Install shipping plate to top of valve and anti-recoil plate to valve outlet. Record date of recharge on inspection tag. Reinstall agent cylinder per Installation Section, Chapter 4. Recharging Nitrogen Cylinders WARNING: Nitrogen actuation cylinders operate at extremely high (1800 psi) pressures. Handle with extreme caution. Perform all recharging with cylinder - contained inside a suitable safety cage. Remove nitrogen cylinder from MRM. Install shipping cap on N2 cylinder. WARNING: Actuator body may have become pressurized as result of system actuation. Unscrew N2 cylinder slowly to allow residual pressure to escape. Service the Nitrogen Cylinders. Clean all N2 cylinders to remove dirt, grease, and foreign material. Check to make sure that the nameplate is in place and fully legible. Inspect the cylinders for corrosion; abrasion, or dents. Relieve pressure and discard if integrity of a cylinder has been compromised. NOTE: When cleaning N2 cylinders, avoid use of solvents. They could seriously damage the gauge face, the gauge guard, or the nameplate. Remove old rupture disc assembly: Install cylinder in a PIN 10270 N2 cylinder recharge adapter. Hold cylinder in place using a 1-1/8 inch wrench on hex portion of N2 cylinder fitting. Loosen rupture disc fitting by turning the recharge adapter wrench 1/4 turn. On cylinders containing previously unruptured discs, allow residual pressure to escape. Unscrew cylinder from recharge adapter. Unscrew old rupture disc assembly and discard. WARNING: Never reuse a rupture disc, even if it appears undamaged. 4. Inspect sealing seat on rupture disc fitting. Discard N2 cylinder if seat is damaged. EX5208. February 5, 2002 Part Number 15040 Reset and Recharge Page 7-8 Install new rupture disc assembly: The rupture disc on Amerex N2 cylinders may be replaced only with P/N 10712. Substitute parts will void manufacturer's warranty. Wipe sealing seat on N2 cylinder rupture disc fitting and copper gasket on new rupture disc with a clean damp cloth. Apply one drop of light machine oil or small amount of petroleum jelly to copper gasket on new safety disc and spread across entire gasket. Screw disc assembly into fitting hand tight. Pressurize N2 cylinder: Reinstall cylinder in PIN 10270 N2 cylinder recharge adapter. Tighten cylinder by hand Ito 1-1/2 turns past contact with sealing gasket. Hold cylinder in place using a 1-1/8 inch wrench on hex portion of N2 cylinder fitting. Loosen rupture disc 1/8 turn. Connect a regulated nitrogen supply to the N2 cylinder recharge adapter. Pressurize the N2 cylinder to 1800 psi at 70 OF. Warning: Check and calibrate regulator gauge at frequent intervals. The regulator gauge should be used to determine when the intended charging pressure has been reached. Do not rely on the nitrogen cylinder gauge for this purpose. Never leave an extinguisher connected to a regulator of a high pressure source for an extended period of time. A defective regulator could cause the cylinder to rupture due to excessive pressure. NOTE: The nitrogen, as it compresses into the N2 cylinder, may experience a significant temperature rise. This temperature rise must be compensated for by pressurizing to the value corresponding to 1800 psi at the higher temperature. The best method to accomplish proper pressurization is to attach a commercially available magnetic base thermometer to the side of the N2 cylinder. Pressurize and hold the cylinder at 1800 psi (Make sure there are no leaks in the nitrogen supply plumbing). Let the apparatus sit for 2 minutes minimum undisturbed to allow the temperature to stabilize. Read the - temperature on the thermometer. Refer to Figure 9.1. Locate the temperature on the "Cylinder Temperature" (horizontal) axis of the graph. Draw a line vertically upward from that temperature until it crosses the "nominal pressure" line. Draw a second line horizontally from the point of intersection to the "charge pressure" (vertical) axis of the graph. Increase the pressure from the regulated nitrogen supply to match the value read from the "charge pressure" axis of Figure 9.3. NOTE: Nitrogen used for pressurizing must be dry with a dew point of -70 OF (-57 °C) or lower. When the determined pressure is reached, tighten the rupture disc by applying a torque wrench to the recharge adapter wrench and tightening (clockwise) to 40 ft. lbs. Shut off nitrogen supply. Bleed and disconnect the supply hose. Remove nitrogen cylinder from recharge adapter. Check for leaks by applying leak detect fluid (soapy water) to the rupture disc, the threads on the rupture disc fitting where it joins the cylinder, and the pressure gauge threads. Look for bubbles in the leak detect fluid. Bubbles may take several minutes to appear. Blow dry fluid from all surfaces and inside of rupture disc following leak detect. Install shipping cap. Reinstall N2 cylinder into MRM per Installation Section, Chapter 4. Make certain that puncture pin of actuator is fully retracted before installing cylinder, and the MRM is properly reset. Purge the Discharge Network: Connect P/N 12129 Discharge Network Blow Out Adapter to the discharge fitting. Blow pressurized dry nitrogen or compressed air through until no dry chemical residue is visible escaping at any nozzle.

Some of these which are commonly used include the following: CAS #: This is the Chemical Abstract Service Number which uniquely identifies each constituent. It is used for computer-related searching. EXPOSURE LIMITS IN AIR: ACGIH - American Conference of Governmental Industrial Hygienists, a professional association which establishes exposure limits. TLV - Threshold Limit Value - an airborne concentration of a substance which represents conditions under which it is generally believed that nearly all workers may be repeatedly exposed without adverse effect. The duration must be considered, including the 8-hour Time Weighted Average (TWA), the 15-minute Short Term Exposure Limit, and the instantaneous Ceiling Level. Skin adsorption effects must also be considered. OSHA - U.S. Occupational Safety and Health Administration. PEL - Permissible Exposure Limit - this exposure value means exactly the same as a TLV, except that it is enforceable by OSHA. The IDLH - Immediately Dangerous to Life and Health level represents a concentration from which one can escape within 30-minutes without suffering escape-preventing or permanent injury. The DFG - MAK is the Republic of Germany's Maximum Exposure Level, similar to the U.S. PEL. NIOSH is the National Institute of Occupational Safety and Health, which is the research arm of the U.S. Occupational Safety and Health Administration (OSHA). NIOSH issues exposure guidelines called Recommended Exposure Levels (RELs). When no exposure guidelines are established, an entry of NE is made for reference. FLAMMABILITY LIMITS IN AIR: Much of the information related to fire and explosion is derived from the National Fire Protection Association (NFPA). IL - the lowest percent of vapor in air, by volume, that will explode or ignite in the presence of an ignition source. UEL - the highest percent of vapor in air, by volume, that will explode or ignite in the presence of an ignition source. TOXICOLOGICAL INFORMATION Possible health hazards as derived from human data, animal studies, or from the results of studies with similar compounds are presented. Definitions of some terms used in this section are: LD - Lethal Dose (solids & liquids) which kills 50% of the exposed animals; LC50 - Lethal Concentration (gases) which kills 50% of the exposed animals; ppm concentration expressed in parts of material per million parts of air or water; mg!m3 concentration expressed in weight of substance per volume of air; mg!kg quantity of material, by weight, administered to a test subject, based on their body weight in kg. Data from several sources are used to evaluate the cancer-causing potential of the material. The sources are: IARC - the International agency for Research on cancer; NTP - the National Toxicology Program, RTECS - the Registry of Toxic effects of Chemical Substances, OSHA and CAL!OSHA. IARC and NTP rate chemicals on a scale of decreasing potential to cause human cancer with rankings from I to 4. Subrankings (2A, 2B, etc.) are also used. Other measures of toxicity include TDLo, the lowest dose to cause a symptom; TDo, LDLo, and LDo, the lowest dose to cause death. REGULATORY INFORMATION This section explains the impact of various laws and regulations on the material. EPA is the U.S. Environmental Protection Agency. WHMIS is the Canadian Workplace Hazard information System. DOT and CTC are the U.S. Department of Transportation and the Canadian Transportation Commission, respectively.
