1 GENERAL

This technical manual provides the necessary information for the design, installation and maintenanceof a Chemetron Argonite Gas Extinguishing System. The content should enable the reader to understandthe operation of an Argonite Gas Extinguishing System for Industrial and Offshore applications.

It has been assumed in the preparation of the various sections of this manual that execution of itsprovisions is entrusted to people appropriately qualified in the specification, design, installation, operationand maintenance of Argonite systems and the associated equipment. In addition, this manual doesnot eliminate the need for system design by trained engineers/designers nor the use of competentengineering judgement.

The manual does not cover detection and control systems, which are to be designed and installedin accordance with national codes and local requirements.

It is important that the fire protection of a building or plant be considered as a whole. Gaseousextinguishing systems form only a part, though an important part, of the available facilities. It shouldnot be assumed that using a gaseous agent system necessarily removes the need to considersupplementary measures, such as automatic fire detection, the provision of fire extinguishers, othermobile appliances for first aid or emergency use, or to deal with special hazards.

For many years, gaseous extinguishants have been recognized as an effective medium for extinguishingordinary Class A fires, flammable liquid Class B fires, and electrical Class C fires. However, in theplanning of comprehensive hazard protection, it should not be forgotten that there may be hazardsfor which these agents are not suitable, or that in certain circumstances or situations there may bedanger in their use requiring special precautions.

Care should always be taken to thoroughly evaluate and correct any factors that could result in unwanteddischarges. It is essential that fire extinguishing equipment be carefully maintained to ensure instantreadiness when required and that the owner be given detailed instruction regarding the operation ofthe systems installed in his building/plant.

1.1 Introduction

The interest in inert gas blends continues to increase due to the phase out of Halon systems inaccordance with the Montreal Protocol and the growing interest in meeting the intent of the KyotoProtocol.

Chemetron's Argonite fire extinguishing system utilizes a 50%/50% mixture of pure Nitrogen and Argon.Both gases are naturally occurring substances and present in the atmosphere, and as such, have noozone depletion potential and no direct global warming risk.

There are no toxicological factors associated with the use of Argonite and Argonite will not decomposeor produce any byproducts when exposed to a flame from a fire condition. However, heat and byproductsof the fire itself can still be substantial and could make the area untenable for human occupancy untilthe enclosure has been properly vented.

Argonite is stored in high-pressure cylinders at a nominal pressure of 2900 psi (200 bar) at 70F(21.1C). Safety and exposure guidelines, including concentration levels, as established by NFPA 2001,Standard for Clean Agent Fire Extinguishing Systems, should be followed.



S/N 30000052


1.2 Use and Limitations

Argonite fire extinguishing systems are primarily used as total flooding systems for protection of self-enclosed equipment or enclosed hazards to contain the extinguishant.

1.2.1 Use

Argonite systems operate safely in temperatures from -20F to 130F (-29C to +54C). Argonite willnot cause fogging during a discharge, a condition caused by the super-cooling of the water contentin the air. The density of Argonite in air is similar to that of atmospheric air, which greatly improvesthe holding time after a release compared with other heavier/lighter agents.

Argonite is electrically nonconductive and therefore suitable for use to extinguish fires in electric andelectronic equipment, such as that found at electronic data processing and telecommunication facilities.Argonite is also useful for extinguishing fires:

Involving flammable and combustible liquids and gases In subfloors and other concealed spaces In tape file storage areas Involving delicate artifacts and high-value assets In places where other extinguishing media could be directly destructive.

Deep-seated fires in solid material require that the Argonite atmosphere be maintained for an extendedperiod of time (holding time) to achieve total extinguishment.

Argonite does not leave any hazardous substances after a release. Since cleanup after a fire will onlyinvolve items damaged in the fire, downtime and secondary damage can therefore be kept to aminimum.

1.2.2 Use Limitations

Argonite should not be used to extinguish fires involving

Chemicals containing their own supply of oxygen and which are capable of rapid oxidation in theabsence of air, such as cellulose nitrate, gunpowder, etc.

Mixtures containing oxidizing materials, such as sodium chlorate or sodium nitrate. Chemicals capable of undergoing autothermal decomposition, such as some organic peroxides and

hydrazine. Reactive metals, such as sodium, potassium, magnesium, titanium and zirconium. Reactive hydrides, or metal amides, some of which may react violently with gaseous extinguishants.

2 FIRE EXTINGUISHMENT METHODS

Argonite systems extinguish fires by the following methods:

2.1 Total Flooding

Release of Argonite into an enclosure (total flooding) means that an inert atmosphere is created withinthe entire room volume.



S/N 30000052


2.2 Selector Valves/Distribution System

If more than one room or hazard in a building is to be protected, a common Argonite cylinder bankmay be used. The capacity of the cylinder bank must be calculated for protection of the largest room/hazard and/or adjoining rooms/hazards that may be involved in a fire simultaneously. In most cases,Argonite selector valve systems reduce the cost as compared to individual systems protecting the samehazards.

2.3 Modular System

In limited space areas where the authority having jurisdiction will allow for a modular system, cylinderslocated singly or in multiple units within the room may be used. The total quantity of stored agent, thenumber of nozzles etc., shall be that as required for a central bank system. Cylinders shall be connectedeither electrically or pneumatically, allowing for simultaneous discharge. Each individual unit shall betreated as a separate system.

3 DESIGN GUIDELINES

Design Guidelines for Argonite systems are as established in NFPA 2001, Standard for Clean AgentFire Extinguishing Systems. Argonite has been designated IG-55 in NFPA 2001 as a blend of two inertgases - Nitrogen and Argon (50% and 50% respectively).

3.1 Design Standards

An Argonite system shall always be designed in accordance with the latest version of applicable designstandards, taking into consideration requirements specified by local authorities having jurisdiction.

NFPA 2001, Standard for Clean Agent Fire Extinguishing Systems

Marine Applications:

Safety Of Life At Sea. Solas, Consolidated Edition

3.2 Personal Safety

CAUTION

WHEN EXTINGUISHING A FIRE USING ARGONITE, THE OXYGEN LEVEL IN THE PROTECTED ROOM IS REDUCEDTO A LEVEL THAT WILL NOT SUSTAIN COMBUSTION. THIS COULD CREATE AN IMMINENT RISK TO PERSONNELOCCUPYING THE ENCLOSURE IF THE RESIDUAL OXYGEN LEVEL BECOMES LESS THAN THAT WHICH CAN SUPPORT

LIFE. PRODUCTS OF COMBUSTION FROM THE FIRE MUST ALSO BE CONSIDERED A HAZARD.

Suitable safeguards shall always be provided to ensure prompt evacuation from and prevent entryinto a hazardous atmosphere, and include a safe means for prompt rescue of any trapped personnel.Safety items such as personnel training, warning signs, discharge alarms, selfcontained breathingapparatus, evacuation plans and fire drills shall be considered and implemented as required.



S/N 30000052


CAUTION

PERSONNEL SHOULD BE ACQUAINTED WITH THE FACT THAT ARGONITE PRESENTS A NOISE HAZARD DURINGDISCHARGE AND MAY RESULT IN DAMAGE TO HEARING IF PERSONNEL ARE PRESENT WITHOUT PROTECTION

DURING DISCHARGE.

Consideration shall be given to the possibility of migration of Argonite to adjacent areas outside ofthe protected space (pressure relief vent openings, etc.).

Argonite systems may be designed for a residual oxygen level of 12% (sea level equivalent) if personnelcan vacate the area within five minutes (exposure time of 5 minutes or less), but may be designedto have a residual oxygen level of 10% (sea level equivalent) if personnel can vacate the area within3 minutes (exposure limited to 3 minutes or less).

WARNING

ARGONITE SYSTEMS DESIGNED TO REDUCE OXYGEN LEVELS TO BELOW 12% SHOULD ONLY BE PROVIDED INNORMALLY UNOCCUPIED AREAS.

Should the possibility exist for the oxygen level to drop below 10%, personnel must be evacuated priorto such oxygen depletion. A design concentration resulting in an oxygen level of less than 10% mayonly be used in normally unoccupied areas, and only if the personnel who could possibly be exposedcan vacate the area within 30 seconds.

However, in all of situations it is necessary that personnel evacuate the hazard prior to system dis-charge. Hence the need to include both predischarge alarms and time delays into all system designs.

Argonite systems designed to concentrations below 42.5% (corresponding to an oxygenconcentration of 12% or higher, sea level equivalent of oxygen) shall be permitted, given thefollowing:

1. The space is normally occupied.2. Means are provided to limit exposure to no longer than 5 minutes.

Systems designed to concentrations between 42.5 and 52% (corresponding to between 12 and10% oxygen, sea level equivalent of oxygen) shall be permitted, given the following:

1. The space is normally unoccupied.2. Means are provided to limit exposure to no longer than 3 minutes.

Systems designed to concentrations between 52 and 61.7% (corresponding to between 10 and8% oxygen, sea level equivalent of oxygen) shall be permitted, given the following:

1. The space is normally unoccupied.2. Where personnel could possibly be exposed, means are provided to limit the exposure to less

than 30 seconds

Systems designed to concentrations above 61.7% (corresponding to 8% oxygen or below, sealevel equivalent of oxygen), shall only be used in unoccupied areas where personnel are notexposed to such oxygen depletion.



S/N 30000052


3.3 Release Time

Industrial: NFPA 2001 recommends 95% of the design quantity of Argonite be released within 60seconds.

Marine: Solas recommends 85% of the design quantity of Argonite be released within 120 seconds.

Other countries/authorities may have different requirements than those mentioned above.

3.4 Temperature Considerations

During a discharge of the agent only, the temperature within the protected enclosure will dropapproximately 10 - 20F (5 - 10C). After the end of the discharge, the temperature will rise again withinapproximately 2 - 3 minutes.

3.5 Electrical Clearance

All system components shall be located to maintain no less than minimum clearance from energizedelectrical parts. Should a design insulation level not be available and where nominal voltage is usedfor the design criteria, the highest minimum clearance listed for this group shall be used.

The following references shall be considered as the minimum electrical clearance requirements forthe installation of clean agent systems:

ANSI C2, National Electrical Safety Code NFPA 70, National Electrical Code 29 CFR 1910, Subpart S NFPA 2001, Standard for Clean Agent Fire Extinguishing Systems

3.6 Automatic Detection and Control

Detection, actuation and control systems shall be installed, tested and maintained in accordance withthe requirements of the authority having jurisdiction.

Automatic detection and actuation (release) is preferred. Selection of the detection devices shall bedetermined based on an evaluation of the flammables involved, the environment and the responsetime anticipated.

Means for manual release of the system shall be provided and located, installed and/or suitablyprotected so that they are not subject to mechanical, chemical or other damage that would render theminoperative.

The control equipment shall supervise the actuating devices and the associated wiring and, as required,cause actuation.

Audible or visual alarms, or both, shall be used to indicate the operation of the system, hazards topersonnel or failure of any supervised device. The device type - audible or visual - their number andlocation shall be such to comply with all local and/or national codes.

Audible and visual predischarge alarms shall be provided within the protected area to give positivewarning of impending discharge. The operation shall be continued after discharge until positive actionhas been taken to acknowledge the alarm and proceed with appropriate action.



S/N 30000052


The time delay between the predischarge alarm and discharge shall be sufficient to allow personnelto evacuate prior to the discharge. Time delays shall be used only for personnel evacuation or to preparethe hazard area for discharge (closing of doors, vents, shut down of equipment, etc.).

4 SYSTEM DESCRIPTION

An Argonite system may involve parts as described below.

4.1 Central Cylinder Bank

An Argonite system normally comprises a bank of cylinders consisting of a sufficient number of cylindersto provide the Argonite supply required. Where required, a reserve bank should consist of as manymultiples of the primary supply as the authority having jurisdiction considers necessary. Main andreserve supplies may be permanently connected to the distribution piping and arranged for easy changeover.

NOTE

IT IS RECOMMENDED THAT A RESERVE BANK OF CYLINDERS ALWAYS BE PROVIDED.

The cylinder bank shall not be located where it can be rendered inoperable or unreliable due tomechanical damage, exposure to chemicals or harsh weather conditions, or by any other foreseeablecause. Where exposure to such conditions is unavoidable, then a suitable enclosure or other protectivemeasures shall be employed.

The cylinders in a bank must be securely supported and attached to a wall or a solid structure in amanner that allows for convenient individual inspecting/servicing. Each cylinder valve must be fittedwith a pressure gauge. A supervisory pressure switch is provided for remote monitoring.

The cylinders in a bank are each connected to a discharge manifold or series of manifolds via flexiblehigh-pressure hoses. The connection at the manifold includes an in-line check valve. Check valvesare provided to prevent agent loss and to ensure personnel safety if the system is operated when anycontainers are removed for maintenance.

It is permissible to utilize multiple storage container sizes in the cylinder bank.

4.2 Selector Valve System/Distribution System

Should the system be designed for protection of more than one hazard from a common cylinder bank,the manifold must be equipped with normally closed, pneumatically operated selector valves.

The pressure required to operate the pneumatic actuators on the selector valves is taken from themain distribution manifold, via a pressure regulator. The pressure regulator reduces the operatingpressure to between 75 and 120 psi (5 to 8 bar) to safely operate the selector valves, and shall includea relief device in case of overpressurization.

S/N 30000052


Figure 4B - Piping & Instrumentation Diagram for Multi-Hazard Argonite System (2 hazards shown)



S/N 30000052


Each selector valve is equipped with its own actuator and solenoid valve assembly, which, whenoperated, will release Argonite into the appropriate hazard area.

A portion of the total number of Argonite cylinders may be used for a particular hazard. This isaccomplished by utilizing a non-return (check) valve in the cylinder pilot line. The system designershall specify the location of the valve.

A restrictor is used at the outlet of each selector valve to reduce the pressure going into the distributionpiping.

Optional isolation (lockout) valves may be installed upstream of the selector valve. These valves mustremain supervised open and may only be closed during system service or routine maintenance.

4.3 Restrictor

The purpose of the restrictor is to reduce the pressure of the gas from the cylinder before it enters thepiping system. The pressure is reduced from the storage pressure of 2900 psi (200 bar).

NOTE

THE CHEMETRON FIRE SYSTEMS ARGONITE FLOW CALCULATION SOFTWARE IS REQUIRED TO DETERMINERESTRICTOR ORIFICE SIZES AND PRESSURE UP AND DOWN STREAM OF THE RESTRICTOR.

4.4 Release Modes

The system is capable of electric, pneumatic and manual actuation and can be released by one ormore of the following methods.

4.4.1 Automatic Release

When a fire condition is detected and the control panel goes into an alarm state, the panel will annun-ciate a visual and/or audible alarm, activate the alarm relay and energize the high-pressure solenoidvalve on the pilot cylinder. In a selector valve system, the low-pressure solenoid valve at the selectorvalve is also energized.

4.4.2 Manual Remote Release - Electrical

Remote release is accomplished by actuation of a switch at a manual release station (if required). Oncethe station has been actuated, the alarm and control panel will operate the system as described above.

4.4.3 Manual Emergency Release

In the unlikely event of total power failure and expiration of the emergency batteries, the system maybe activated by pulling the pin and rotating the actuator handle. In a selector valve system, the manualoverride on the selector valve for the desired area must also be operated.

NOTE

THE GREEN HANDLE ON THE TOP OF THE CYLINDER VALVE IS NOT FOR MANUAL OPERATION AND SHOULD NOTBE USED FOR THE OPERATION OF THE SYSTEM.



S/N 30000052


4.5 Cylinders

Each cylinder is fitted with a pressure operated Argonite cylinder valve. The cylinders are availablein 15.9, 66.7 or 80 liter capacity and filled with Argonite at a pressure of 2900 psi (200 bar) at 70F(21.1C). The cylinders are provided with a protective cap and grey shoulder markings.

4.5.1 Cylinder Valves

Each valve is to be provided with a pneumatic operator to open the valve; one of the cylinder valvesin the bank must be fitted with a manual/pneumatic actuator. A pressure gauge with supervisorypressure switch is provided for local and/or remote monitoring of cylinder pressure.

The pilot cylinder in a bank is provided with a pressure gauge/solenoid valve actuator unit allowingfor electrical release. In event of release by the use of pressure through the manual/ pneumatic actuatorson the slave cylinders, the pilot cylinder will provide pressure for their opening. The interconnectionbetween pilot and slave cylinders is accomplished using high pressure flexible hoses.

After a discharge, the cylinder valve will automatically close when the pressure decreases to approxi-mately 45 psi (3 bar), maintaining a positive pressure as well as preventing moisture from enteringthe cylinder and thus ensuring corrosion protection of the interior of the cylinder.

4.5.2 Pressure Monitoring

Chemetron offers means for remote and local pressure monitoring of the content within the cylinder.

The local monitoring is by the use of the pressure gauge on each cylinder. The remote monitoring is by the use of a pressure gauge with supervisory pressure switch on each

cylinder. The switch, which is normally under pressure, consists of one normally open contact thatcloses to annunciate loss of pressure at approximately 2200 psi (150 bar).

4.6 Selector Valves

In systems where a common cylinder bank protects more than one hazard, selector valves are utilized.The selector valve is a pneumatically actuated ball valve, sized according to the system requirements.

In systems where remote indication of release into a specific area is required, a discharge pressureswitch can be fitted downstream of the selector valve.

The solenoid valve energized by the fire alarm/control panel will provide pressure to the pneumaticactuator on the valve. The solenoid valve will close when de-energized, however the ball valve mustbe closed manually.

4.7 Distribution Pipe Network and Nozzles

The distribution pipe network is to be designed and the nozzles selected and positioned to allow aneven distribution of the Argonite throughout the protected area. The piping and fittings should conformto NFPA 2001, Power Piping Code, and all local codes and standards.



S/N 30000052


4.8 Flow Calculations

Flow calculations are to be based on the design drawings and should be verified prior to installationof the nozzles. Any significant changes should be evaluated, and if necessary, the flow calculationrepeated and orifices in restrictor and nozzles replaced to ones suitable for the as-built situation.

All calculations to determine the size of restrictor orifice pipe dimensions and nozzle orifices must becarried out utilizing the approved Argonite software.

4.9 Pressure Relief Venting

When released, fixed fire extinguishing systems employing compressed gases will create a considerableextra volume of gas within the room due to expansion. To compensate for the overpressure, suitablemeans of pressure relief venting must be employed. The free area of these openings/vents shall beappropriately sized to avoid structural damage.

Normal rooms will withstand an increase of pressure of approximately 5 millibars (2 in. H O). Pressure2relief vents should be located at a high level on the wall or on the ceiling, clear of any direct nozzledischarge. At the end of the discharge the pressure relief vents shall close in order to maintain theextinguishing concentration for as long as possible.

The fire rating of all pressure vents should be equal to or greater than the rating of the structure.

4.10 Service and Maintenance

The importance of maintenance cannot be overemphasized. Trained personnel shall regularly servicean Argonite system. The service engineer shall be proficient in the installation and commissioning ofArgonite systems as well as have detailed knowledge of the involved components.

At least annually, all systems shall be thoroughly inspected and tested for proper operation. Theinspection should include a verification of the integrity of the protected volume and assurance thatthe protected volume has not increased or decreased. Changes in installed equipment occupyingadditional or less volume than at the design/installation stage will affect the resulting oxygenconcentration after a discharge. A recalculation of the system may be required.

NFPA 2001 requires that if an Argonite cylinder shows a loss in pressure (adjusted for temperature)of more than 5% (2750 psi at 70F or 190 bar at 21.1C) it shall be refilled or replaced. The cylinderpressure gauge reading shall be compared to a separate calibrated device at least annually.

Refer to Chapter 9 for further service and maintenance procedures.

5 SYSTEM BASICS

The cylinders are installed in racks available in single, dual or quadruple row configuration.An Argonite system may consist of one or more cylinders, connected through a common dischargemanifold arrangement (cylinder bank).The cylinders in the bank are connected to a common release manifold arrangement via highpressure hoses and a check valve assembly, one for each cylinder. The check valves allow removalof one or more cylinders from the manifold.The cylinder valves are constructed to be capable of releasing of 80 liters at 2900 psi (200 bar)within 1 minute.The system can be released manually by removing a safety pin and turning the actuator handle.The manual release unit is mounted on the side of the pilot cylinder valve.

NOTE

THE GREEN HANDLE ON THE TOP OF THE CYLINDER VALVE IS NOT FOR MANUAL OPERATION AND SHOULD NOTBE USED FOR THE OPERATION OF THE SYSTEM.

The cylinders are provided with a pressure gauge assembly and the pilot cylinder is also providedwith a solenoid valve/manual release/gauge assembly.When energized, the solenoid valve will provide pressure for opening all of the cylinder valves.The pressure from the pilot cylinder is fed to pneumatic actuators on the slave cylinders.The manifold arrangement is further equipped with restrictor(s), which reduce the discharge pipingpressure during the discharge.Selector valves may be used to divert Argonite to the required hazard.From the restrictor, Argonite is fed through a piping system to the nozzles, which distributes thegas in the room.An Argonite system is to be monitored and controlled by the building fire alarm and control panelor a local fire alarm and control panel (depending on local approval and/or requirements). Firedetectors for each hazard shall be selected based on the flammables involved, their burning rateand the accepted response time.The room should be evacuated before discharge in order to secure both the extinguishing effectas well as human safety (secure the hazard during and after the release). The control panel maybe equipped with a time delay of 10 - 30 seconds (depending on requirements of authorities havingjurisdiction). The warning alarm shall start sounding simultaneously with the start of the time delayperiod.

5.1 Extinguishing EffectArgonite is a 50/50 mixture of Nitrogen and Argon (N /Ar). When Argonite is discharged, an inert2 atmosphere is created in the protected hazard. Within a short time, the fire will be suffocated as theoxygen content will decrease from the normal 20.9% to 15-10% (depending on the flammables involved).

For most flammable liquids and solid materials, a 15% oxygen level is the lowest limit at which a firecan be sustained; however 30% safety factor requirements result in the 12.5 - 13% oxygen level. A12% oxygen level is the lowest limit acceptable for personnel occupancy in the protected hazard/room.

NOTE

IN ORDER TO ACHIEVE EXTINGUISHMENT OF SOME MATERIALS, IT IS NECESSARY TO LOWER THE OXYGEN LEVELBELOW 10%. THESE SYSTEMS REQUIRE SPECIAL SAFETY PRECAUTIONS.

Figure 6.6A - Typical Selector Valve System Arrangement

6.6 Selector Valve Systems

Selector valves are used in multiplehazard systems where Argonite may besupplied to different hazards from thesame cylinder bank. Refer to Figures6.6 and 4B for layouts of typical selec-tor valve arrangement.

Systems that utilize differing numbersof cylinders for each hazard MUST usea pilot line non-return (check) valve (S/N70985013). This valve allows for aportion of the pilot line to be used forsystem activation, as needed. Separatepilot cylinders must be used for eachhazard. For example, in Figure 4B whenthe Zone 1 pilot cylinder is activated,only 4 cylinders will discharge into themanifold. When the Zone 2 pilot cylin-der is activated, all nine cylinders willdischarge. The pilot line non-returnvalve (Figure 6.6B) allows for the properamount of Argonite to be dischargedinto each hazard.

Using the standard primary completerkit assembly(s), the cylinders to bereleased are discharged into the discharge manifold(s). At the end of the discharge manifold, customersupplied fittings and/or a selector manifold is used to contain the Argonite pressure until the properselector valve is operated to release Argonite into the hazard area. The selector valves operate pneu-matically or manually.



S/N 30000052


Figure 6.6B - Non-return (check) Valve for Pilot Lines(S/N 70985013)

The pressure required to operate theselector valves is taken from thedischarge manifold via a pressureregulator assembly (S/N 20980095).One common regulator is used to re-duce the operating pressure to 120 psi(8.3 bar) for selector valve actuation.

Each selector valve is equipped with itsown actuator and is supplied with a 24VDC 3-way solenoid. When actuated,the solenoid will route pressure to theactuator to open the selector valve.Once opened, the selector valve willremain open until manually closed.

Restrictors for each hazard area are to be installed downstream of their respective selector valves.

NOTE

ALL DISCHARGE PIPING UPSTREAM OF THE RESTRICTORS, INCLUDING THE SELECTOR VALVE MANIFOLD, MUSTBE SCHEDULE 160 OR STRONGER.

The selector valve manifold or piping configuration is supplied by others (not Chemetron) and mustinclude a 3/4" relief valve (S/N 70985027) and a 1/4" NPT fitting for connection of the pressure regulator.The relief valve and regulator are supplied as part of the pressure regulator kit (S/N 20980095).

6.6.3 Isolation (Lockout) Valve Assemblies

Isolation (lockout) valves may be installed formaintenance/service reasons; for multi-hazardsystems they are typically installed upstream of theselector valve as illustrated in Figure 4B. For singlehazard systems, the isolation valves shall belocated upstream of the restrictor. These devicesMUST be locked in the OPEN position wheneverthe Argonite System is in operational/standbycondition. When the discharge piping is beingserviced, these valves MUST be locked in theCLOSED position.

Isolation valve assemblies include a high visibilityindicator and limit switch (weatherproof or explo-sionproof). The limit switch shall initiate a Troublesignal at the control panel when the ball valve isin the closed position. All ball valves have aworking pressure of 2900 psi (200 bar). When using isolation valves, a pressure relief valve shouldalso be installed wherever pressure could be trapped in closed sections of pipe.

6.7 Restrictor/Orifice

The high-pressure 2900 psi (200 bar) Argonite is discharged into the distribution pipe network througha restrictor assembly. During agent flow, the restrictor reduces the initial manifold pressure before theagent enters the distribution piping. The size of the orifice is calculated based on the required dischargetime and the required flow.
