This manual is intended for use by qualified marine firesuppression specialists responsible for designing Kidde FireSystems. Marine Carbon Dioxide Systems aboard USCGinspected vessels. In addition to this manual, the systemdesigner should be familiar with the NFPA Standard No. 12(Carbon Dioxide Extinguishing Systems, latest edition), CFRTitle 46 Shipping, Chapter I, Navigation and Vessel Inspec-tion Circular No. 6-72 “Guide to Fixed Fire-Fighting Equip-ment Aboard Merchant Vessels,” the rules for the applicableship classification society (ie: ABS, DNV, ect..) and Inter-national Maritime Organization “International Maritime Con-vention for Safety of Life at Sea (SOLAS).” Note that SOLASrules usually apply only to vessels that make internationalvoyages.

1-2 AGENT CHARACTERISTICS

CO2 is a compound of carbon and oxygen. A gas at normal

pressures and temperatures, CO2 is colorless, odorless,and electrically non-conductive. It is approximately 50%heavier than air. Primarily, CO2 suppresses fires by re-ducing the available oxygen in the atmosphere to apoint where combustion can no longer take place.Additionally, CO2 provides a secondary desirable coolingeffect and leaves no residue. It dissipates into the atmo-sphere after the discharge, allowing for rapid clean-up andminimal equipment downtime.

WARNING!

Because CO2 reduces the available oxygen in

the atmosphere, it will not support life. Caremust be taken to ensure all personnel areevacuated from the protected space prior todischarging the system. A suitable warningnotice must be prominently displayed in clearview at the point of entry into the protected areato alert personnel of the asphyxiation propertiesof CO2.

1-3 EFFECTIVENESS

CO2 is an effective agent for Class A (wood, paper, etc.),Class B (flammable liquids and gases), and Class C (elec-trical equipment) hazards. CO2 must be applied with dueconsideration to the hazard being protected and its con-tents. Rapidly developing fires such as those found in en-gine and pump rooms must be extinguished quickly withCO2 to minimize heat buildup. In contrast, a fire in a cargohold containing wood or paper is controlled with a slowerCO2 discharge and the hold may have to be kept inert for aconsiderable time to ensure complete extinguishment.

Carbon dioxide must not and cannot be used on Class D(reactive metals, metals hydrides and chemicals contain-ing their own oxygen supply) hazards, such as magnesium,potassium, sodium, and cellulose nitrate. These Class Dfires can only be controlled by special extinguishing agentsand procedures.

CAUTION!

IMPORTANT - READ CAREFULLY

The carbon dioxide and nitrogen gases usedin these systems are stored in cylinders atextremely high pressures. An uncontrolledrelease of this high pressure gas from anaccidental discharge, improper handling, ordamage to parts can result in a violent and rapidpropulsion of the cylinder(s), capable ofcausing severe property damage, personalinjury, or death. All the warnings andinstructions noted in this manual must befollowed for the safe handling, installation,transportation, service and inspection of thecylinders.

CHAPTER 2SYSTEM DESIGN

2-1 GENERAL

USCG CO2 systems provide suitable fire suppression forfive distinct categories, depending on the nature of the haz-ard and the protected space. The categories are:• Dry cargo spaces• Enclosed ventilation systems for rotating electrical pro-

pulsion equipment• Machinery spaces, pump rooms, paint lockers, etc.• Vehicle cargo spaces• Semi-portable hose reelsThe CO2 requirements and discharge rates vary, dependingon the nature of the protected space, and the gross volumeof the compartment. The space must first be identified andassigned into one of the five categories listed above. Oncecategorized, the required amount of CO2 can be determined,along with discharge rates, pipe sizes, etc.

2-2 DRY CARGO SPACES

2-2.1 General

Cargo compartment fires generally involve Class A combus-tibles. The fire will generally start as a slow, smoldering typefire, producing large amounts of smoke. Once sufficient heathas developed, the fire will dramatically increase in inten-sity. A USCG approved fire detection system should be usedto detect the fire while it is still in the smoldering stage.

Once a fire has been detected, all openings to the spacemust be closed. An initial amount of CO2 can then be dis-charged until a sufficient concentration has been developedto bring the fire under control. With the openings still sealed,additional CO2 can be discharged from time to time to main-tain the proper concentration. The space is kept closed un-til the vessel reaches port. At port, the hold can be opened,the cargo can be removed, and final extinguishment can beaccomplished with additional CO2, water, or other agents.

2-2.2 System Design

The amount of CO2 required can be determined by dividingthe gross volume of the space (in cubic feet) by 30. Thecargo space is defined as the volume between watertight orfirescreen bulkheads, and from the tank top or lowest deckto the deck head of the uppermost space on which the cargomay be carried. If a trunk extends beyond such deck, thetrunk volume must be included in determining the CO2 re-quirement. All tonnage openings can be considered as sealedfor this purpose.

Because of the nature of the fire hazard, no specific dis-charge rates need be applied to these systems. However,the discharge piping to the various holds and between decksmust not be less than 3/4 inch in size.

2-3 ELECTRICAL PROPULSION EQUIPMENT

2-3.1 General

Electrical propulsion equipment fires generally involve ClassC combustibles, and can be deep seated in nature. Usuallyan initial discharge is provided to quickly suppress any sur-face flames, and an extended discharge is provided to main-tain the CO2 concentration until the equipment can bestopped. This type of system generally involves two sepa-rate discharge lines and nozzles. On small systems, onecommon discharge line may be used for both the initial andextended discharge. If the initial discharge is such as toachieve the required concentration until the equipment isstopped, no delayed discharge is necessary.

2-3.2 System Design

The amount of CO2 required for the initial discharge can bedetermined by dividing the gross volume of the system by10 (for spaces less than 2,000 cubic feet). For spaces equalto or greater than 2,000 cubic feet, divide the gross volumeby 12. The initial discharge must be completed within twominutes.

The amount of CO2 required for the extended discharge isdependent on the gross volume, the time it takes to stopthe equipment, and the amount of air movement in the sys-tem. Sufficient CO2 must be provided to maintain a mini-mum 25% concentration until the equipment can be stopped.Refer to NFPA 12 for guidance as to how the required amountof CO2 is calculated.

2-4 MACHINERY SPACES, PUMP ROOMS,PAINT LOCKERS, ETC.

2-4.1 General

Fires in machinery and similar spaces generally involve ClassB combustibles. Contrary to cargo compartments, fires inmachinery spaces develop rapidly and can become intensein a short period of time. For this reason, it is critical thatCO2 be discharged quickly. Rapid discharge and extinguish-ment prevents the heat/fire from damaging equipment, bulk-heads, and other structural members.

2-2P/N 220610 November 2008


2-4.2 System Design

The amount of CO2 required for the compartment is equal tothe gross volume of the space divided by the appropriateflooding factor shown in Table 2-1. If the flammable liquidcan drain or spread to an adjacent space, the sum of thecompartment volumes shall be used to determine the re-quired amount of CO2. The system must be arranged to dis-charge CO2 simultaneously into both compartments.

The volume of the machinery space must exclude the nor-mal machinery casing unless the boiler, internal combus-tion machinery, or fuel oil installations extends into the space.In such an instance, the volume shall include the top of thecasing, or the next material reduction in casing area, which-ever is lower.

The definition of “normal machinery casing” is a casing thearea of which is less than 40% of the maximum area of themachinery space. “Material reduction in casing area” is de-fined as a reduction to at least 40% of the casing area.These definitions do not apply to vessels contracted for priorto October 1, 1959.

For vessels on an international voyage contracted for afterMay 26, 1965, the amount of CO2 for a space containingboilers and/or internal combustion machinery used for pro-pulsion must be as follows: Divide the gross volume (ex-cluding the casing) of the space by the appropriate factorreferenced in Table 2-1 or divide the entire gross volume(casing included) by a factor of 25, and use the larger of thetwo amounts. A minimum of 85% of the required amount ofCO2 must be discharged in two minutes.

2-5 VEHICLE CARGO SPACES

2-5.1 General

Vehicle cargo (Ro/Ro) space fires generally involve Class A(rubber, plastics, and other ordinary combustibles), Class B(flammable liquids), and to a lesser extent, Class C com-bustibles. These type fires propagate slowly but becomeintense and grow rapidly as they progress. Care should betaken to quickly develop and maintain the CO2 concentra-tion for a sufficient period of time to ensure complete extin-guishment.

2-5.2 System Design

The amount of CO2 required is calculated by dividing thegross volume (in cubic feet) of the largest space by 22. Be-cause of the nature of the fire hazard, 2/3 of the requiredamount of CO2 must be discharged within 10 minutes. Fasterdischarge times are permissible.

2-6 HOSE REEL SYSTEMS

2-6.1 General

In addition to the previously mentioned “fixed” type systems,hose reels provide a semi-portable means of dischargingCO2 directly onto the burning material. Hose reel systemsprovide a large volume discharge, much greater than thatavailable from hand-held portable fire extinguishers, and areintended for smaller hazard applications. Personnel evacua-tion and equipment shutdown may sometimes be avoidedby the use of these semi-portable units. The units them-selves are generally located within the protected space inan open area, so that all portions of the space may be cov-ered to provide quick response to an emergency.

2-6.2 System Design

Sufficient CO2 is provided for at least a one minute discharge.The discharge is controlled by a hose mounted shut-off valvelocated directly upstream of the hand-held nozzle. The hose,which interconnects the shut-off valve with the reel/rack, isavailable in various sizes and lengths to meet the hazardrequirements. The hose reel and rack are equivalent in termsof effectiveness, although the reel is easier to manipulate.

2-7 EFFECTS OF VENTILATIONAND UNCLOSEABLE OPENINGS

The proper control of a fire by a CO2 system depends on theintegrity or “tightness” of the enclosed space. Any agentleakage from the space will reduce the effectiveness of thesystem. Large leaks or openings will render the system in-effective.

In spaces where a ventilation system is installed, the venti-lation system must be shutdown prior to the CO2 discharges.This shutdown must be accomplished automatically by theoperation of the CO2 system (via pressure operated switchesor releases). Complete ventilation shutdown must be ac-complished before the CO2 system is discharged. If the ven-tilation system cannot be shut down, an additional amountof CO2 must be added to compensate for the effects of theloss through the ventilation system.

Uncloseable openings in the space will also adversely affectthe CO2 system. Depending on the quantity, size, and loca-tion of the openings, additional agent will be required. Theamount of additional agent and the discharge rate shall bein accordance with NFPA 12. A discharge test is recom-mended to verify the effectiveness of the CO2 system andthe integrity of the protected space.

2-3November 2008 P/N 220610


2-8 CYLINDER SELECTION AND STORAGE

Once the amount of CO2 has been determined, the nextstep of the system design process is to determine the ap-propriate size and quantity of CO2 storage cylinder(s). Referto Table 2-2 for selection of the appropriate cylinder size.

Table 2-2. Cylinder Configurations

100 81-870269/81-100067-003

3AA-2300/3AA-2130 4-1

All cylinders on a common manifold must be of the samesize. Cylinders should be located as near to the protectedspace as possible. The cylinders must be located outsidethe protected space, except for spaces which require nomore than 300 lbs. of CO2. Cylinders installed outside theprotected space must be in an accessible location to per-mit manual actuation in the event of fire (without the need togo through any of the protected spaces). The cylinders mustbe located such that the ambient storage temperature rangefalls between 0°F and 130°F. Additional heating or cooling ofthe space may be required to maintain this temperaturerange.

CO2 cylinders are equipped with a burst disc to relieve ex-cessive pressure within the cylinder. If the cylinders are lo-cated adjacent to the protected space, enough heat may beconducted through bulkheads or decks to rupture the burstdisc. Should this occur, the CO2 storage room would befilled with agent and little, if any, would be available to extin-guish the fire. Therefore, common bulkheads and decksbetween CO2 storage rooms and protected spaces must beprotected with A-60 structural insulation. Cylinders must notbe located in any space that might be cut off or made inac-cessible in the event of a fire in any of the spaces protected.

2-9 SYSTEM CONTROLS

System actuation can be accomplished by three methods:1. Automatic, via pneumatic heat actuated devices (for

spaces which require no more than 300 lbs. of CO2).2. Remote-manual, via cable or pneumatic releases.3. Local-manual, via mechanical means at the storage

cylinders themselves.

2-10 AUTOMATIC ACTUATION

For spaces requiring no more than 300 lbs. of CO2, the USCGpermits the use of automatic actuation. This is accomplishedby utilizing a pneumatic detection system. This systememploys the rate-of-rise principle. A sudden increase in tem-perature will cause the system to actuate.

Heat actuators are located throughout the hazard, and areinterconnected to pneumatic control heads (located on thepilot cylinders) via copper tubing. When the air within theheat actuator becomes heated due to a fire within the pro-tected space the air expands and builds up pressure in theactuator. The pressure is then transmitted through the cop-per tubing to the pneumatic control heads. When sufficientpressure has built up (the amount ranges from one to sixinches of water column), the pneumatic control heads willoperate and discharge the system.

The pneumatic control heads are fitted with vents, so thatslight changes in pressure, due to normal changes in ambi-ent temperature, can be vented to atmosphere.

Heat detectors are installed no more than 10 feet from abulkhead; spacing must not exceed 20 feet, center-to-cen-ter, or 400 square feet per detector. The use of more thanfour detectors will require a mercury check.

2-11 REMOTE-MANUAL ACTUATION

Remote-manual actuation can be accomplished via cableor pneumatic releases. Cable operated pull boxes are avail-able in various configurations. The pull boxes are connectedto the control heads (located on the storage cylinders orstop valves) via 1/16 inch stainless steel cable. Corner pul-leys are used to change direction of the cable routing. Thecable should be routed in 3/8 inch schedule 40 pipe.

The USCG mandates that the maximum force required tooperate the pull box may not be greater than 40 pounds, norrequire a movement greater than 14 inches. No more than15 corner pulleys and 100 feet of cable should be used withcontrol head, P/N 81-979469-000 and 6 corner pulleys withany pneumatic control head. If other combinations of cornerpulleys and lengths of cable are required, the 40 lb. maxi-mum force and 14 inch maximum travel requirements mustnot be exceeded.

As an alternate to the cable operated system, Kidde FireSystems. also offers a pneumatic actuation system. Thesystem consists of a nitrogen actuation cylinder, which isconnected to the CO2 pilot cylinders by pipe or tubing. Nor-mally, the pneumatic system is used only when the maxi-mum requirements for the cable system cannot be met.Limitations on pilot lines are shown in Table 2-4.

2-12 DISCHARGE NOZZLES

Kidde Fire Systems offers three basic types of total floodingtype discharge nozzles: Type “V,” “S,” and “M.”

2-12.1 Type “V”

Type V nozzles have a 1/2-inch NPT inlet connection andare generally used with electrical propulsion equipment andventilation systems. The V nozzle can accommodate CO2flow rates up to approximately 100 lbs./min. The nozzlesmust be spaced approximately 15 to 20 feet apart. Thenozzle(s) should be strategically located to provide optimumCO2 distribution. A strainer is provided with V nozzles thathave orifice codes less than 5 to prevent foreign objects inthe pipe from clogging the nozzle orifice. A flange and coverassembly is available for ease of installation and to preventforeign objects from entering the piping network.

2-12.2 Type “S”

Type S nozzles also have a 1/2 inch NPT inlet connection,and are generally used with machinery spaces, pumprooms, etc. The S nozzle can accommodate CO2 flow ratesup to approximately 100 lbs./min. In addition to the stan-dard S nozzle, flanged and zinc plated versions are avail-able where installation requirements dictate. The nozzles

must be spaced every 20 to 30 feet apart at a height equalto approximately 1/3 the height of the space. Additional tiersof nozzles may be required for spaces with multiple levels.Strainers are provided with those nozzles having orifice sizesless than 6. A flange and cover assembly is also availablefor the flanged S nozzle.

2-12.3 Type “M”

For large machinery spaces and pump rooms where greaterquantities of CO2 are required, type M nozzles are utilized.Having a 3/4 inch NPT inlet connection, the M nozzle willaccommodate flow rates up to 225 lbs./min. The nozzlesmust be spaced every 20 to 30 feet apart at a height equalto approximately 1/3 the height of the space. Additional tiersof nozzles may be required for spaces with multiple levels.Strainers are provided with those nozzles having orifice sizesless than 6.

2-13 PIPE AND FITTINGS

Once the discharge nozzles have been selected and located,the distribution piping can be routed. The route utilizing theleast amount of pipe and fittings must be used to minimizefriction loss. The piping must extend at least two inchesbeyond the last nozzle of each nozzle header (branch line)to prevent clogging. All pipe and fittings must be galvanizedinside and out.

Pipe and fittings must be in accordance with 46 CFR Sub-chapter F, Parts 54 through 56 as follows:

2-14 INSTALLATION TEST REQUIREMENTS

Upon completion of the piping installation, a pressure testmust be done on the piping network. Test with CO2, nitro-gen, or dry air. The CO2 cylinders must be disconnectedand the manifold inlets plugged.

The piping from the cylinders to the directional (stop) valvesmust be pressurized to 1000 psi. With no additional gasbeing added, the pipe must maintain pressure for a twominute period. The maximum pressure loss permitted is 150psi per minute.

The piping downstream of the directional (stop) valves mustbe tested in a similar manner with the exception that theinitial pressure shall be 600 psi instead of 1000 psi. For thepurpose of this test, the piping must be capped within theprotected space at the first joint upstream of the nozzles.

For small, independent systems (e.g., protecting emergencygenerator rooms, paint lockers, etc.) the above test can bewaived provided the piping is blown out with CO2, nitrogen ordry air of at least 100 psi and the cylinder is installed in theprotected space.

2-15 PIPE AND NOZZLE SIZE CALCULATION

To determine the proper discharge pipe and nozzle sizes,the following method must be followed:1. Determine the appropriate amount of CO2 required for

the space as described in Sections 2.2 through 2.6.2. Calculate the nominal cylinder outlet area (sq. in.) by

multiplying the lbs. of CO2 required by the factor 0.0022.The minimum nominal cylinder outlet area shall be 0.110sq. in.

3. Using the amount of CO2 calculated in step 1, refer toTable 2-5 to determine the correct pipe size for eachbranch.

4. Using the size for the main supply pipe as determinedin step 3, refer to Table 2-6 to obtain the internal area ofthat pipe size.

5. Calculate the equivalent nozzle orifice area by dividing45% of the nominal cylinder outlet area (step 2) or 45%of the supply pipe area (step 4), whichever is smaller,by the total number of nozzles.

6. Referring to Table 2-10, compare the value calculated inStep 5 with the various equivalent nozzle areas avail-able. Choose the closest area and corresponding ori-fice code number.

7. To calculate the total nozzle orifice area, multiply theequivalent nozzle area chosen in Step 6 by the totalnumber of nozzles. The total equivalent nozzle orificearea should not exceed 85%, nor be less than 35% ofthe nominal cylinder outlet area (Step 2), or the area ofthe supply pipe (Step 4), whichever is smaller.

Refer to Chapter 8 for an example of the calculation method.

2-16 DISCHARGE MANIFOLD

To assure proper actuation of slave cylinders, it is recom-mended that the cylinder manifold be sized based upon to-tal pounds of CO2 discharging through that section of the

2-6P/N 220610 November 2008

Marine CO2 Fire Suppression Systemsmanifold. Table 2-5 is to be used as a guide to determinethe pipe sizes required.

Recommended maximum pipe size for straight pipe mani-fold is one pipe size smaller than the supply pipe, but in nocase shall the manifold exceed 1½ inch in size.

CHAPTER 3SYSTEM ARRANGEMENTS

3-1 GENERAL

The USCG has different requirements for SOLAS class andnon-SOLAS class vessels. SOLAS classification (compli-ance with SOLAS rules) is required for vessels that oper-ate on international voyages. For guidance on applicabilityof regulations and order of precedence, please see theForeword of this manual.

The following schematics depict typical USCG approvedsystem arrangements. These schematics will assist the de-signer in selecting the proper arrangement and componentsto best suit a particular application. Table 3-1 provides thedesigner with a general system arrangement overview forquick reference purposes. Each arrangement is providedwith a “sequence of events” description to explain the pri-mary method of system operation.

3-2 DISCHARGE DELAY UNITS

The Kidde Fire Systems carbon dioxide system has tradi-tionally used discharge delay units that use the extinguish-ing agent to generate the delay period of nominally 30 or60 seconds. These units are still listed and approved andwill remain available for the foreseeable future. Howeveras a result of changes in the regulatory environment KiddeFire Systems has included it’s nitrogen driven dischargedelay unit in the carbon dioxide product line and arrange-ments for this edition of the manual. The nitrogen delayprovides improved performance with a set-up that was con-figured to meet the current regulatory approach to accept-ability criteria.

The USCG follow NFPA 12 guidance on the acceptabletolerance for the actual discharge delay period observedduring testing. This guidance requires the actual delay tobe no less than the stated nominal delay period and nomore than the nominal delay plus 20%. Local inspectorsmay accept CO2 delay units that exceed the positive end ofthe tolerance. One reason for this is the capability of dis-charge delay to be by-passed using the attached controlhead. However they are unlikely to accept a unit that cyclestoo quickly.

In this chapter there are four new arrangements that illus-trate alternative methods of system configuration using thenitrogen discharge delay units. Each of the new arrange-ments offers the same functionality. We recommend thatthe nitrogen delay be considered for new applications to

reduce the incident of problems during inspections and otherperiodic testing.

3-3 ARRANGEMENT NUMBER 1

Arrangement Number 1 is a system protecting a single space, requiring no more than 300 lb. of CO2. One, two, or threecylinders are required, with storage located outside the protected space. System actuation is accomplished by means ofcable operation. An emergency method of operation is provided at the cylinder location. All the control heads are equippedwith a manual operating lever with a lead wire sealed pull-pin to preclude accidental operation. In the event the cableoperated pull-box fails to discharge the system, personnel can be instructed to activate the system via this manualoperating lever.

Primary system activation is accomplished using the remote located, cable pull box. After it has been verified that nopersonnel are in the space, the cable pull box is operated. This causes the cable control head located on the pilot CO2cylinder to operate, causing the cylinder to discharge. The discharged CO2 is directed to a pressure operated switch,which shuts down ventilation and/or equipment, and then to a pneumatic operated siren (optional). The siren warnspersonnel of the simultaneous discharge. The agent is then directed into the space via the pipe and nozzle network.

3-5 ARRANGEMENT NUMBER 3A, WITH CO2 DISCHARGE DELAY

Arrangement Number 3A is designed for protection of a single space, requiring more than 300 lbs. of CO2. Three or morecylinders are required, with storage located outside the space. Actuation is accomplished pneumatically, using a nitrogenpilot cylinder.

System actuation is initiated by operating the lever control head mounted on the nitrogen cylinder and opening the accom-panying ball valve. The nitrogen pressure is transmitted to the pressure control heads located on the CO2 cylinders,causing the cylinders to discharge.

The CO2 is discharged into the manifold, and is directed to the normally closed stop valve. A portion of the discharge isrouted to the pressure switch, siren and discharge delay. This will cause the pressure switch to operate, and the alarm tosound. The time delay will begin to cycle, and upon completion, will open. This portion of the discharge will be routed to thelever/pressure control head on the stop valve, causing the stop valve to open. The main portion of the discharge will thenpass through the stop valve and be directed to the nozzles.

Personnel must be instructed to actuate the stop valve manually, by operating the lever/pressure control head in the eventof a time delay failure.

A safety relief is provided in the event the cylinders have discharged and the stop valve does not operate. If pressure build-up in the manifold becomes excessive, the safety relief will rupture, venting the pressure to the atmosphere.

4-4 REMOTE NITROGEN ACTUATOR

The remote nitrogen actuator is a 108 cubic inch cylinder pressurized to 1,800 psi. A lever operated control head is installedon the nitrogen cylinder valve for actuation purposes. A 1/4 inch ball valve is installed in the actuation piping downstream ofthe nitrogen cylinder. Once the lever operated control head and ball valve are opened, the nitrogen pressure is routed to thelever/pressure operated control head mounted on the pilot CO2 cylinders, discharging the system. The nitrogen cylinder isequipped with a pressure gauge and safety relief device.

The 1040 cu. in. and 2300 cu. in. pilot nitrogen system cylinders are comprised of seamless steel cylinders manufacturedto Department of Transportation (DOT) requirements. The discharge valve is forged brass and has a nominal 5/8” dischargepath. The assembly is installed without a siphon tube. The nominal charge pressure is 1800 PSIG at 70°F (124 bar gaugeat 21°C).

The valve is fitted with a safety burst disc to protect against over-pressurization. A horizontal axial threaded connection onthe side of the valve is utilized for filling and for actuation. The threaded portion of the upper valve is where the discharge headis located (see Figure 4-11 and Table 4-1).

WARNING!

Pressurized (charged) cylinders are extremely hazardous and, if not handled properly, are capable ofviolent discharge. This could result in death, personal injury or property damage. Always handle chargedcylinders according to the instructions in this manual and applicable federal codes.

Pilot nitrogen cylinders (1040 and 2300 cu. in.) are factory-equipped with a protection cap threadedsecurely over the valve assembly. The device is a safety feature and provides protection during shippingand handling. The cap must be installed at all times, except when the cylinder is connected into thesystem piping or is being filled. Do not move or handle a cylinder unless the protection cap is installed.Ensure that the protection cap is retained in a safe place close to the installed cylinder on the vessel.

5-15 PNEUMATIC DETECTOR.

Pneumatic detectors must be installed on the ceiling; UNDER NO CIRCUMSTANCES are detectors to be installed on theunderside of beams. Refer to installation drawing(s) for quantity and location of detectors.

Connect the detectors to the control head with 3/16 inch tubing provided by Kidde-Fenwal, Inc. Secure tubing every 18inches with clips provided. The actuator tubing furnished with this system is of special extra heavy construction and isespecially resistant to damage. The tubing is furnished in approximately 12 foot lengths with both ends flared. It is fitted witha tube fitting and protection cap to prevent entrance of moisture or foreign matter. Because the tubing is difficult to flare,Kidde-Fenwal, Inc. recommends the entire length be used. Excess tubing should be taken up by coiling. See Figures 4-12through 4-15 for details of the tubing and fittings required. Test and inspect detector in accordance with Chapter 7, Mainte-nance.

WARNING

DO NOT USE ANY TYPE OF COPPER TUBING OTHER THAN THAT WHICH IS SUPPLIEDBY KIDDE-FENWAL. THIS TUBING IS A SPECIAL GRADE OF TUBING. ORDINARY TUB-ING IS VERY EASILY DAMAGED AND MAY CAUSE FAILURE OF THE SYSTEM.

5-20P/N 220610 November 2008


NOTE: If tubing is installed in an area where it may be subjected to mechanical damage, it is permissible to run the tubingthrough 1/2 EMT to protect tubing from damage.

5-16 PNEUMATIC CONTROL HEAD.

The following procedures must be performed before attaching control head to cylinder valve.

1. Remove pilot port outlet protection cap from valve of cylinder to be equipped with control head.

2. Be sure control head is in SET position.

5-17 PRESSURE SWITCHES

Pressure switches must be connected to the pilot piping or discharge manifolds as shown on the system drawings. Thepreferred mounting position is upright, as shown on Figures 5-1, 5-2, and 5-3. Both the standard and explosion-proofpressure switches have 1/2 inch NPT pressure inlets to connect to the piping. The electrical connections are either 1/2 inchconduit knockouts or 1 inch NPT fittings.

5-18 DISCHARGE TIME DELAY

The time delays are pre-set at the factory; however the actual delay period is dependant on the specific installation, ambienttemperatures and the test methodology. USCG requires that a time delay must be tested during commissioning andinspection. To meet the pass criteria, the tested delay period must fall in the range minus zero percent and plus twentypercent (-0%, +20%) of the factory rated value. This range is based on the guidance provided in NFPA 12:2000 Standard onCarbon Dioxide Extinguishing Systems.

USCG recognizes that the range of installation configurations coupled with the inherent variability of metered carbon dioxideas a timing medium make compliance with this specification challenging. In general some allowance may be granted fordelay periods that exceed the twenty-percent figure since the time delay unit (P/N 81-871071-000, or P/N 81-897636-000)can be bypassed using the lever operated control head (P/N 870652). Delay periods less than the factory rated value are notacceptable since they potentially compromise the safe egress of personnel from the protected space. The improved reliabil-ity of the N2 driven units make such consessions unnecessary.

FURTHER CYLINDERREMOVAL OR CYLINDER REPLACEMENT MUST ALWAYS BE SUPERVISED TO ASSURE FULLCOMPLIANCE WITH THE INSTRUCTIONS IN THIS MANUAL.

1. Remove control head at the coupling nut only (if control head not present, proceed to Step 3).

2. Attach protection cap to the actuation port.

3. Loosen cylinder framing so that cylinders can move freely.

4. Hook scale on weighing angle and slip yoke under discharge head. Adjust lever as shown in attached dia-gram (Figure 7-1).

5. Pull down until cylinder is just clear of floor and lever is horizontal.

6. Read weight directly off scale (scale is calibrated to compensate for leverage). Empty cylinder weight isstamped on the cylinder valve body; therefore, deduct empty weight from scale reading. Also, deduct 3.75lbsfor weight of discharge head. The result is the amount (charge weight) of liquid carbon dioxide in the cylinder.

7. If charge weight loss exceeds 10%, proceed as follows:

a. Disconnect discharge head from cylinder valve (DISCHARGE HEAD MUST BE LEFTCONNECTED TO THE DISCHARGE HOSE AND SYSTEM PIPING TO PREVENT INJURY INTHE EVENT OF DISCHARGE).

b. Install the valve protection cap on cylinder

c. forward charged cylinder WITH DISCHARGE HEAD AND CONTROL HEAD REMOVED ANDSAFETY CAP AND PROTECTION CAP INSTALLED to a recognized Kidde Fire Systemsdistributor.

7-7 PNEUMATIC DETECTION SYSTEM TESTS. (FIGURE 7-2)

CAUTION!

Before conducting any of the tests outlined below, remove the pneumatic control heads from the cylinders.

WARNING!

WHEN DISCONNECTING CONTROL HEADS (TANDEM MOUNTED) DO NOT LET THEHEADS TURN (IF INTERCONNECTING CABLE HOUSING IS A LOOSE FIT), THIS WILLPREVENT ACCIDENTAL DISCHARGE.

Pneumatic Control Head Test

1. Connect the test fitting of the manometer test set to the diaphragm chamber of the control head.

2. Make certain sufficient clearance is provided at mounting unit so control head will not be damaged uponoperation.

3. If control head has been operated, reset by placing screwdriver in reset stem and, turning clockwise untilstem locks in position (with arrow on reset stem lined up with “SET” arrow on nameplate).

4. Use manometer test set P/N WK-840041-000 (see Figure 7-2) and pour water into the open tube until the waterlevel in both tubes is exactly at the zero mark. (The test set is not furnished as part of the system).

5. Close off the rubber “A” by squeezing tightly with the fingers or use a crimp clamp, and then apply pressure bygradually squeezing the rubber bulb “C.” The control head must operate at the factory pressure setting plus orminus the 10% tolerance allowed. The pressure required to operate the control head is the difference, in

P/N 220610 November 20087-6


inches, between the water levels in the two tubes, and is equal to twice the reading of either tube, i.e., 3 inchesboth tubes or 1-1/2 inches on one tube.

CAUTION!

After the control head has operated, be sure to release rubber tube “A” first before allowingthe rubber bulb “C” to expand to normal; otherwise water may be sucked into the tubing andcontrol head, causing serious problems.

7-8 CONTROL HEAD VENT TEST

Before disconnecting manometer from the control head, the vent must be tested. To test the vent for correct calibration,perform the following steps:

1. Squeeze rubber bulb “C” about halfway or enough to achieve sufficient vacuum for test, then close tube “A” bypinching with fingers or crimp clamp.

P/N 220610 November 20087-7


2. Let bulb expand gradually to its normal shape. This creates a partial vacuum, causing the water level to change,indicating inches of vacuum applied to the control head (the vacuum must be more than a minimum of 3 inchesin order to observe drop from 3 inches to 1 inch).

3. The water column will recede to “0” level as air passes through the vent. The time required (number of seconds)for the water column to recede 2 inches reading from 3 inches to 1 inch on both legs or 1 1/2 inch to 1/2 inch oneither leg is the number of the vent (the calibrated rate of flow), i.e., if the time required to pass the aboveamount of water is 5 seconds the control head vent is “No. 5.” When vents are tested, the time will vary due tothe added volume in the control head diaphragm chamber. A No. 5 vent may test at 5-7 seconds, which isacceptable. If a vent time reads much higher, it will increase system sensitivity and may not be acceptable.Table 7-2 shows the acceptable times allowed when testing for vent sensitivity using manometer method withvent installed in the control head.

Repeat above procedure for testing tandem control head if installed. Since there is no vent in the tandem control head, thevacuum must hold (same as tubing tightness test).

4. Disconnect manometer test set from the control head (test fitting “A”). Reset the control head by turning thereset stem to its “SET” position.

NOTE: For accuracy, Kidde Fire Systems manometer test set, P/N WK-840041-000, must be used.

7-9 TEST FOR LEAKAGE OF SYSTEM TUBING AND DETECTORS

1. Connect the test fitting of the manometer to the pneumatic detector tubing (at the control head connection nut).

2. Squeeze the rubber bulb “C” fully and then close off the open rubber tube “A.” Very gradually, release the rubberbulb to its normal shape. This will cause the water level in the two tubes to change, at which time a maximumvacuum will develop. Hold a minimum 8 inch vacuum (difference between two sides of “U” tube, or 4 inches oneach side of “U” tube).

3. If all connections are absolutely tight, the water level will remain in the position taken in item 2 above and willnot change as long as the rubber tube “A” is held closed. Observe the level of the water for at least one minuteand then release the rubber tube “A.” It is absolutely essential that the water level remain the same as long asthe rubber tube is held closed. Even a slow, steady fall of the water level is serious, for it indicates a leak whichmay prevent automatic operation of the system. Disconnect the test set from the detector tubing. After testshave been completed, reset the control heads.

WARNING!

WHEN USING HOT OR BOILING WATER, EXERCISE CARE WHEN IMMERSING THE ACTUATING CHAMBER.DO NOT STAND DIRECTLY BENEATH THE CONTAINER.

P/N 220610 November 20087-8


4. Functional Test of System. Hold a container of hot or boiling water under the heat detector, immersing theactuating chamber in the water. At least 50% of the detector must be immersed. The water must be at least100°F above the ambient temperature. Note the time between the application of the hot water to the detectorand the operation of the control head. The control head must operate in approximately 15 seconds. Do notapply heat for more than 15 seconds. The detector is not functioning if the control head has not operatedwithin this time.

When testing two control heads connected in tandem, both may not operate simultaneously. Both controlheads must operate within 15 seconds if the heat is sustained.

5. The heat test must be performed on each heat detector. Between each test, wait about five minutes for thesystem to return to normal, and then reset the control head. To reset, insert screwdriver in the reset stem andturn clockwise until the stem locks in position with the arrow or reset stem lining up with the “SET” arrow on thenameplate (slight resistance will be met just before the stem locks).

6. If the application of heat does not cause the control head to operate within 15 seconds, remove the container ofwater and investigate cause:

a. Heat differential was inadequate.

b. Leakage in the tubing system (tubing connections not tight).

c. Obstruction in the tubing.

7-10 TROUBLESHOOTING OF PNEUMATIC DETECTION SYSTEM

Failure of system to operate pneumatic detection system testing when applying heat to the detectors may be caused by:insufficient heat applied, obstructions in tubing, or leaks in system. The manometer can be used to assist in troubleshoot-ing the system a follows:

1. Install manometer in system tubing at pneumatic control head connection. Replace union connection with acontrol heat “T.” Close open tube “A” of the manometer (see Figure 7-2) with crimp clamp. The manometer isnow an integral part of the system and provides a visual record of pressure to which system is subjected byheat or cold at the detector.

2. The installation of the manometer as described above provides a visual indication of the pressure buildup withinthe system and will assist in determining if there is sufficient or insufficient pressure buildup during test of thesystem.

8-1 GENERAL

This section describes the calculation methods that are used to determine the quantity of CO2 required as well as pipe andnozzle sizes. These methods are the same as those described in the US Coast Guard Navigation and Vessel InspectionCircular (NVIC) 6-72, Part II.

Example (See Figure 8-1)

To illustrate the calculation methods, assume that the protected enclosure is a machinery space with a volume of 12,000 ft3.

From Section 2-15 Step 1:

Determine CO2 quantity required, refer to Sections 2-2 through 2-6. From Table 2-1 for 12,000 ft3, use flooding factor = 20 ft3/lb:

Qty = Volume/Flooding factor

Qty = 12,000 ft3/20 ft3/lb.

Qty = 600 lbs. CO2

From Section 2-15, Step 2:

A. Calculate the Nominal Cylinder Area:

Nom. Cylinder Area = Qty CO2 x 0.0022

Nom. Cylinder Area = 600 lbs x 0.0022

Nom. Cylinder Area = 1.32 in2

B. Determine Supply Pipe Area:

The minimum supply pipe for 600 lbs. CO2 = 1-1/4" pipe (Table 2-5). Internal pipe area of 1-1/4" pipe = 1.283 in2

(See Table 2-6).

C. Compare the nominal cylinder outlet area to the supply pipe and select the smaller of the two. In this example,the supply pipe area is smaller; therefore, the nozzle orifice area must be based on this smaller value of 1.283in2.

From Section 2.15, Step 5:

A. Select the nozzle orifice sizes by multiplying the area selected in Step 2C above by 45%; then divide by thetotal number of nozzles. In this case, assume (4) nozzles of equal size:(1.283 x .45)/4 = 0.144in2/nozzle


A. Then, select the nozzle with the closest equivalent single orifice area (see Table 2-7):

Use Code 14 with area = 0.1503 in2

CHAPTER 8SAMPLE CO2 CALCULATIONS

8-2P/N 220610 November 2008


B. Calculate total equivalent nozzle orifice area:

0.1503 in2 x 4 = 0.6012 in2


A. Calculate the percent total nozzle orifice area to supply pipe area:

% = Total Nozzle Orifice Area x 100%

Supply Pipe Area

% = 0.6012 in2 x 100% = 46.9% of supply pipe area

1.283 in2

B. Compare the calculated percent total nozzle orifice area to the minimum 35% and maximum 85% allowed.Since the calculated value in this example falls within the stated range the nozzle selection is satisfactory. Ifthe calculated value falls outside of this range, the nozzles must be resized until the calculated value doessatisfy this criteria.

From Section 2.15, Step 8 Determine Pipe Sizes:

A. The quantity of CO2 delivered by each nozzle can be assumed to be directly proportional to the ratio of theindividual nozzle orifice area to the total nozzle orifice area multiplied by the quantity of CO2 supplied.

In this example, all four nozzles are the same size and can be considered to deliver an equal amount of CO2:

600 lbs/4 = 150 lbs/nozzle

B. Determine the quantity of CO2 carried by each pipe section, then select a pipe size for each pipe section usingTable 2-5:

APPENDIX DOBSOLETE EQUIPMENT

D-1 INTRODUCTION

This appendix contains information concerning equipment and components that were previously provided as part of thesystem or as an option for the system but are no longer available for procurement.

D-2 OBSOLETE EQUIPMENT

The obsolete items contained in this appendix are:• Smoke Accumulator• "Y" Check Valve .• Throttle Check Valve

D-3 SMOKE ACCUMULATOR

The smoke accumulator is used as a smoke sampling device and as a a carbon dioxide nozzle in a cargo-hold suppressionsystem.

Figure D-1. Smoke Accumulator, P/N 63339

D-2P/N 220610 November 2008


D-4 "Y" CHECK VALVE

The "Y" check valve is used to isolate two carbon dioxide cylinders from a larger bank of cylinders in a cargo-hold suppres-sion system. This allows one to discharge two cylinders at a time in a multiple cylinder installation.

Figure D-2. "Y" Check Valve, P/N 800759

D-5 THROTTLE CHECK VALVE

The throttle check valve is a combination tee and check valve used to isolate two pilot cylinders in a cargo-hold suppressionsystem. The installation of this device allows one to discharge two cylinders at a time without operating the pilot cylindersand causing a discharge of all cylinders.
