Kidde Fire Systems

High Pressure Carbon Dioxide Fire Suppression System Kidde Fire Systems High Pressure Carbon Dioxide (HPCO2) fire suppression system is the ideal fire suppression solution for heavy and light industrial applications where unoccupied spaces or assets need protection, where CO2 is an acceptable agent and other agents would be cost prohibitive, and where in addition to the primary total flooding design, a local application system may be required. CO2 agent is stored in seamless steel cylinders as a liquid under its own vapor pressure and at ambient temperature.

FEATURES

Environmentally safe

• CO2 is naturally occurring gas

• Global Warming Potential (GWP) of One (1)

• Ozone Depletion Potential (ODP) of Zero (0) Since CO2 is a gas, it can penetrate and spread to all parts of the protected area. As a gas or as a finely divided solid called 'snow' or 'dry ice', CO2 will not conduct electricity and therefore, can be used on energized electrical equipment. CO2 also leaves no residue, thus eliminating cleanup of the agent itself. Additionally, CO2 is low-cost, therefore can be used on deep-seated fires and oils, fats and greases where larger agent quantities are required.

CO2 Suppression system is the only clean agent system that can be used for deep seated fires.

Suppression System Configuration HPCO2 systems may be configured for total flooding, local application, or both.

Total Flooding: In a total flooding system, a predetermined amount of CO2 is discharged through fixed piping and nozzles into an enclosed space or enclosure around the hazard. Total flooding is applicable when the hazard is totally enclosed and when all openings surrounding the hazard can be closed auto-matically prior to or at the start of system discharge. If all the openings cannot be closed, additional CO2 must be provided to compensate for agent loss through these openings during the discharge and appropriate concentration retention periods. The CO2 concentration must be maintained for a sufficient period of time to allow the fuel and any other surfaces or equipment in contact with the fuel to cool below the ignition temperature of the combustibles.

Local Application: Local application systems differ from total flooding in that the nozzles are arranged to discharge directly onto the fire. One of the principal uses of local- application sys-tems is to protect open tanks containing flammable liquids, but this technique can be generalized to protect three-dimensional hazards such as paint spray booths and printing presses.

CO2 systems can also consist of hand hose lines permanently connected by means of fixed piping to a fixed supply of suppression agent. These systems are frequently provided for manual protection of small, localized equipment. Although not a substitute for a fixed system, a hose line can be used to supplement a fixed system where the hazard is accessible for manual firefighting.

Cylinder and Valve Assemblies The agent cylinders are steel and equipped with a forged brass valve assembly which contains a safety disc device for protection against over pressurization due to elevated temperatures. Each valve is equipped with a side port that serves both as a fill connection and as a control port for attachment of a variety of Kidde Fire Systems control heads.

The threaded connection on the top of each valve mates with a discharge head to allow agent release and distribution into the system piping.

High pressure CO2 hardware has been in service for more than 50 years. The hardware is time-tested and has gained the trust of our cus-tomers and end users.

Cylinder Rack and Framing, Example Arrangement Single and double mounting straps are available for all cylinder sizes. However to provide flexibility of installation for three or more cylinders, three different styles of framing arrangements available:

Arrangement A This style (Figure 1) is used for a single row of cylinders, that can be either wall mounted or free standing.

Figure 1. Multiple Cylinder Mounting, Arrangement A Arrangement B This style (Figure 2) provides for one row of cylinders on each side of the framing. This arrangement is free standing and requires two aisles. It has the advantage of permitting free access to any cylinder without disturbing any other cylinder.

Figure 2. Multiple Cylinder Mounting, Arrangement B

WARNING

Cylinders are shipped from the factory with a protection cap installed that pre-vents impacts and damage to the valve during the transportation.

K-81-1000 3

Arrangement C:

This style (Figure 3) provides for a double row of cylinders on the same side of the framing. This arrangement can be free standing or wall mounted. It is generally used when the cylinders are to be wall mounted and sufficient space is not available to arrange them in a single row.

Figure 3. Multiple Cylinder Mounting, Arrangement C Larger quantities of cylinders can be accommodated by adding additional framing. All framing is supplied with pre-drilled mounting holes. Any combination of cylinder stowage, junction box installation, pneumatic selector valve installation and cylinder manifold support can be accommodated by the holes in the framing. All bolts and nuts are supplied as part of the framing. Drilling is not required at the job site in order to erect the bracketing. In addition the cylinder manifolds are arranged to be fastened to the framing.

Discharge Manifold HPCO2 Agent cylinders can be manifolded together as an End, Center, or H setup, with additional options for a for connected Main and Reserve systems.

Figure 4. Typical Manifold Layout

Discharge Heads Each cylinder and valve assembly must be equipped with a discharge head at installation to actuate the cylinder valve. The discharge head is assembled to the top of the cylinder valve and contains a spring-loaded piston which when actuated by CO2 pressure is designed to depress the main check in the valve and discharge the contents of the cylinder. The piston provides the necessary mechanical advantage to open the valve's main check. The discharge outlet is designed to mate with a flexible hose or swivel adapter for connection to the distribution piping.

The discharge head also contains an integral stop check whose function is to automatically prevent the loss of CO2 during system discharge in the event that a cylinder is removed from the distribution piping. Two different style discharge heads are available:

Discharge Hoses Flexible discharge hoses are used to provide the interconnection between the discharge head and the distribution manifold or piping. The hoses are made of wire-reinforced rubber.

A 1/2 in. flexible discharge hose is used with the 25, 35, and 50 lb cylinders. The 3/4 in hose is used with the 75, 100, and 123 lb cylinders.

Control Heads Actuation of the suppression system is initiated by use of control head(s). Control heads are components that attach to the control ports of the CO2 cylinder valves. The control head initiates the suppression system discharge by opening the cylinder valve's pilot check. This allows CO2 to pressurize the discharge head piston, which opens the main check in the valve and discharges the contents of the cylinder.

One control head is used for CO2 systems having one or two cylinders. A minimum of two control heads are required for suppression systems that have three or more CO2 cylinders.

Control heads are also used in conjunction with pressure operated time delays, stop valves, and pneumatic transmitters to control the flow of CO2 throughout the piping network. All of the control heads are self-venting in the set position to prevent accidental discharge in the event of a slow build-up of pressure in a pilot line or a slow leak at the pilot check of the cylinder valve.

There are multiple types of control heads available:

Note: For more information on each control head type, see the corresponding datasheet.

Check Valves Check valves serve to isolate a specific section of the suppression system from the entire system. Check valves are used in all fire suppression systems that are equipped with a main and reserve set of CO2 cylinders. The valves are installed in each discharge manifold to isolate the main and reserve cylinders from each other. Check valves are also used in systems incorporating directional valves where a common set of CO2 cylinders to protect areas or equipment of unequal sizes.

The check valves divide the cylinder group into subsets for discharge of the required amounts of CO2 into the protected areas or equipment. Check valves are available in sizes ranging from 1/4 to 3 in. diameter. The 1/4-inch and 3/8-inch check valves are also used in Nitrogen or CO2 pilot lines.

Stop (Directional) Valves Stop (Directional) valves allow cost-effective protection for facilities with several assets requiring protection. Stop valves find two primary applications in CO2 systems. The first application is in multi-hazard systems which share a common CO2 suppression system. Stop valves are used to route the CO2 from the shared supply to the individual areas or equipment being protected.

The second application for these valves is as a life safety device to prevent the accidental discharge of CO2 into a normally occupied area. The stop valve prevents the flow of CO2 until the attached control head is operated.

All Kidde Fire Systems Stop valves operate on a differential-pressure principle, using the pressure of the discharging CO2 to open the stop check and allow flow through the valve. All valves automatically reset (close) after discharge is completed.

Stop valves are available in sizes ranging from 1/2 to 4 in.

diameter.

For more information, see K-81-5130.

Lockout Valves A lockout valve is a manually operated valve installed between the CO2 manifold and the discharge pipe to the protected area.

The lockout valve can be locked in the closed position to prevent CO2 from discharging into the protected area. The lockout valve shall be installed at the end of the CO2 manifold or, if a common manifold protects multiple hazards, after each selector valve.

The lockout valve consists of a carbon steel or stainless steel valve with threaded ends. Either valve style can be provided with or without limit switches. Lockout valves are available in sizes ranging from 1/4 to 4 in. diameter.

Figure 7. Lockout Valves with Lock The lockout valve without limit switches is available in sizes 1/4” through 2”. The lockout valve with 2 SPDT limit switches and indicator is available in sizes 1/4” through 2”. The lockout valve with 2 SPDT explosion proof limit switches and indicator is available in sizes 1/4” through 2”. For more information, see K- 81-1300, K-81-1310, and K-81-1320.

Discharge Nozzles

Figure 8. HPCO2 Nozzles (Type S, Type M, Type V with Flange, and Type L)

Discharge nozzles control the distribution of CO2 into the protected area for total flooding or onto the protected equipment for local application. These discharge nozzles are designed to provide the proper combination of flow rate and discharge pattern to protect vital equipment. See Table 3 for more information on nozzle styles and applications.

Discharge nozzles are marked to identify the nozzle and show the nozzle's equivalent single orifice diameter. The equivalent diameter refers to the orifice diameter of a "standard" single orifice type nozzle having the same flow rate as the discharge nozzle.

Strainers are provided with nozzles having smaller orifice sizes to prevent foreign objects in the pipe from clogging the nozzle orifice.

A Flange Mounting kit is available for Type S Multijet and the Type V Vent nozzles.

Note: See flow calculation report for nozzle part numbers and drill codes.

Multijet Nozzle, Type S The type S multijet nozzles have a female 1/2 in. NPT inlet connection for attaching to the distribution piping. The basic type S nozzle has a red painted cold-rolled steel body. A flanged type S nozzle and flanged mounting kit are also available for placing the nozzle on the exterior of a duct or enclosure. The flanged mounting kit includes a frangible disc which ruptures upon discharge. The flanged nozzle and mounting kit may be used to prevent particulate and liquid matter from clogging the orifices.

The flanged nozzle body is painted red.

Figure 9. Multijet Nozzle, Type S Flanged For more information, see K-81-1130 and K-81-1170.

Multijet Nozzle, Type M The type M multijet nozzle is similar in design and operation to the type S multijet nozzle, and is used for applications requiring higher flow rates than those attainable with the type S nozzle.

The nozzle body is longer than the type S body in order to accommodate the higher flow rates. The type M nozzle has a red painted, cold-rolled steel body and a 3/4 in. NPT inlet connection for attaching to the CO2 distribution piping.

Figure 10. Multijet Nozzle, Type M For more information, see K-81-1150 and K-81-1170.

Vent Nozzle, Type V The type V vent nozzle is a single-orifice nozzle used to discharge a jet of CO2 into an enclosure such as a duct. The type V nozzles are only used for total flooding applications.

Figure 11. Vent Nozzle, Type V For more information, see K-81-1110, K-81-1120, and K-81-1170.

Multijet Nozzle, Type L The type L multijet nozzle has a 1/2-inch NPT female connection for attaching to the CO2 distribution piping. The discharge produces a 180o flat fan pattern that is highly effective for protection of dip tanks, drain boards and similar two dimensional hazards. The nozzle is attached to the side of a tank and offers no obstruction to overhead trolleys or dipping operations.

The type L nozzles are only used for local application systems.

Figure 12. Multijet Nozzle, Type L

K-81-1000 7

Hand Hose Line Systems A Hand Hose Line System consists of a hose reel or rack, hose, and a discharge nozzle assembly connected by fixed piping to a supply of CO2.

Hand hose line systems may be used to supplement fixed fire protection systems or to supplement first response portable fire extinguishers for the protection of specific hazards for which CO2 is a suitable extinguishing agent. These systems shall not be used as a substitute for other fixed CO2 fire-extinguishing systems equipped with fixed nozzles, except where the hazard cannot adequately or economically be protected by a fixed system. The decision as to whether hose lines are applicable to the particular hazard shall rest with the authority having jurisdiction.

Hand hose line systems shall be placed such that they are easily accessible and that the hose length is adequate to reach the most distant hazard. In general, they should not be located where they will be exposed to the hazard, nor shall they be located inside any hazard area protected by a total flooding system.

If multiple hose stations are used, they shall be spaced so that one or more hose lines can cover any area within the hazard.

Figure 13. Typical Hand Hose Line System with Reel

PRESSURE OPERATED SIRENS

The Pressure Operated Sirens are used as audible alarms in and outside the hazard, warning those in the area to evacuate.

These units discharges CO2 when operated.

Note: When the CO2 discharge occurs outside the hazard, the discharge does not contribute to a firefighting concentration and the total system agent quantity must be compensated to account for the CO2 discharged by the siren.

Figure 14. Pressure Operated Siren

DISCHARGE DELAY DEVICES

Discharge delay devices are designed to delay the discharge of CO2 for an appropriate period of time to allow for an orderly and safe evacuation from the protected area. Discharge delays also provide a time interval for equipment to shutdown and auxiliary interlocks to engage prior to the agent discharge. Discharge delays are used to control the length of the pre-discharge warning period by holding back the actuation of a stop valve which prevents flow of CO2 into the hazard area. Discharge delays can use either the CO2 agent or a Nitrogen pilot cylinder to operate.

ODORIZER ASSEMBLY

CO2 is odorless and colorless. Therefore for the safety of personnel who may occupy the hazard area, odorizer assemblies are required with each CO2 system regardless of size. Odorizers are used to inject wintergreen scent into the CO2 discharge as a means to warn occupants of the presence of CO2. Upon discharge, the CO2 pressure ruptures a burst disc to release the scent intermixing it with the CO2.

Figure 16. Odorizer For more information, see datasheet K-81-9162.

DISCHARGE INDICATOR

The discharge indicator,installed on the system, gives clear visual indication of a system discharge.

Figure 17. Discharge Indicator For more information, see datasheet K-85-0527.

SAFETY OUTLET

Use a safety outlet for pressure relief of manifold arrangements using directional valves

Figure 18. Safety Outlet For more information, see datasheet K-81-5170.

DISCHARGE PRESSURE SWITCH

Provides a pressure operated electrical switch. Once operated by system pressure, the switch can be used to enunciate alarms, shut down ventilation and/or other electrical equipment and turn on electrical automatic dampers or other necessary equipment.

Figure 19. Discharge Pressure Switch For more information, see datasheet K-81-5180.

PRESSURE TRIP

The pressure trip provides a pressure operated mechanical quick release to close dampers, shut spring loaded shutoff valves, and other similar applications

Figure 20. Pressure Trip For more information, see datasheet K-81-5200.

WARNING SIGNS

Warning signs shall be posted inside and outside all areas protected by a CO2 system, and in adjoining areas where the CO2 could migrate. These warning signs instruct the occupants to evacuate the area immediately when the alarms operate, as well as to warn personnel not to enter the protected space after a CO2 discharge until the area has been safely ventilated. Kidde Fire Systems offers different safety warning signs with wording specific to each application.

HPCO2 Component Description Type “I” Cylinder Valve, 5/8 in.

With Typical Cylinder

P/N: WK-840253-000

DESCRIPTION

Kidde Fire Systems' High-Pressure Carbon Dioxide (CO2) Fire Suppression Systems use a forged brass dis-charge valve to dispense CO2 from the 75-lbm or 100-lbm capacity cylinder assemblies. A US DOT compliant safety relief device, protecting the cylinder from over pressurization, is provided as part of the discharge valve assembly. A side port functions as a fill connection or as an attachment point for a compatible control head. Since the CO2 is stored under its own vapor pressure, a pres-sure gauge is not provided.

The discharge valve cannot dispense the cylinder con-tents without a properly attached discharge head. A dis-charge flex hose connects the discharge head to the system manifold. Alternatively, a swivel adapter may be used in place of a discharge flex hose to connect to the system manifold.

The discharge valve is provided as part of the HPCO2 cylinder assembly. A discharge head and flex hose need to be ordered for each cylinder assembly.

HPCO2 Component Description

75 and 100 lbm Capacity Carbon Dioxide Cylinder and Valve Assemblies

DESCRIPTION

The Kidde Fire Systems High-Pressure Carbon Dioxide (CO2) Fire Suppression System uses seamless steel cyl-inders to store carbon dioxide agent. The agent is stored under its own vapor pressure as a non-flammable com-pressed gas. Due to the physical properties of CO2, both the vapor and liquid state are present within the cylinder.

Each assembly is factory fitted with a discharge valve and siphon tube. A US DOT compliant safety relief device, protecting the cylinder from over pressurization, is provided as part of the discharge valve assembly. For shipment, a standard shipping cap is included, which mates to external threads on the cylinder neck to protect the discharge valve from inadvertent damage.

Prior to removing the shipping cap, each cylinder shall be properly secured using cylinder straps or Framing/Oak Rack Kits as required.

The discharge valve cannot dispense the cylinder con-tents without a properly attached discharge head. This feature provides an enhanced safeguard during trans-port. A discharge flex hose connects the discharge head to the system manifold. Alternatively, a swivel adapter may be used in place of a discharge flex hose to connect to the system manifold. One or more control heads will be required to actuate a manifold of cylinders.

After discharge, charging accessories are required to safely vent any residual pressure to service the dis-charge valve and then re-fill the cylinder.
