Kidde engineers developed carbon dioxide fire extinguishing over 80 yearsago and Kidde have been responsible for every major improvement that hasbeen made in this branch of fire protection. Kidde Fire Protection benefitsfrom the accumulated experience of thousands of installations in powerplants, industrial plants, oil refineries, electronic processes, on ships and in awide variety of hazardous areas.

Total Flooding SystemsTotal flooding systems extinguish firesby rapidly discharging CO 2 into anenclosed volume to create anatmosphere that is incapable ofsupporting combustion.

The agent mixes homogeneously in

the risk area to generate a CO 2concentration by volume of at least34%. This concentration of CO 2presents a serious hazard to personneland under no circumstances shouldCO2 be released into areas that may bemanned at the time of discharge.

Automatic CO 2 Extinguishing System

Total flood CO 2 systems are ideal forunmanned applications such astransformer rooms, remote switchrooms, generators and archives. Allsystems should be installed with safetysystems in place to prevent theinadvertent release of agent intooccupied spaces. Kidde Fire Protection

offers time delays, isolating valvesincluding distribution valves andcontrol head lockout pins to facilitatethe safe use of CO 2.

Local ApplicationThis method of system design is usedto protect hazards that are open orhave only partial enclosure, situatedwithin a larger area that would beunsafe or uneconomic to protect usinga total flood system. Discharge nozzlesare placed so as to provide direct

agent flow at the points and areasprone to fire. The direct contact of therapidly expanding CO 2 providesefficient cooling and the gasdramatically reduces the oxygenconcentration in the hazard zone.

Mechanical Automatic, Local Application CO 2 Extinguishing System

Local application systems are designedto provide extremely fast discharges toknock down the fire in a matter ofseconds. These systems are veryeffective and are often installed withconnected reserve banks so that thesystems can be reinstated during thesame shift as a fire event, while the

empty cylinders are recharged.

testing. If the test shows that theleakage would reduce the hold timebelow that specified for the fire type,additional CO 2 must be provided.

The release of CO 2 into a tightly sealedenclosure could result in damagecaused by pressure variations during

discharge. Normally the naturalleakage of an enclosure is adequate toprevent damage but in some casespressure relief venting may berequired.

System InformationLocal Application Systems

This protection methodology is wellsuited to painting, dipping and dryingtype applications.

Surface FiresFires involving flammable liquids,gases or solid materials not subject tosmouldering are known as surfacefires.

The design concentration of CO 2provided must be maintained for 10minutes.

Basic quantities of CO 2 for variousspace volumes may be calculated fromTable 1.

Direct-acting CO 2 solenoidDesigned for use with standardKidde Fire Protection 45kg CO 2cylinders, the direct-acting solenoidallows CO 2 systems to be actuatedelectrically without the need for aseparate pilot nitrogen supply.

The solenoid actuation system uses amodified version of the existingcylinder valve, replacing the nitrogenpilot cylinder with a solenoid directlycoupled to the CO 2 cylinder valve. Thesystem also retains the facility for localmanual release or via a mechanicalpull cable.

In the unactivated state, thepneumatic actuator is subject only toatmospheric pressure and the Klemvalve remains closed. On receipt of anelectrical signal from an extinguishantrelease control panel, the solenoid coilis activated, releasing high pressureCO2 from the cylinder. The CO 2 passes

through a short flexible hose to thepressure/manual actuator, which thenoperates the Klem valve, allowing CO 2to exit via the discharge port. FurtherCO2 cylinders may be discharged byinterconnecting the pressure/manualactuators using flexible pilot hoses(K93433).
