FM 200 OVERVIEW

FM-200

Developed in 1980’s, environmentally friendly alternative to halon

1301

First system installed 1992

UL listing / FM approval 1994

Hundreds of thousands of systems in over 70 countries

FM-200 Originally Manufactured by Great Lakes Chemical Corporation (GLCC)

FM-200 Great Lakes Chemical Corporation - Formerly largest producers in the world of Halon

1211 and Halon 1301

FM 200 FEATURES

FM 200 has no hazardous physic-chemical properties or health effects and it meets all criteria laid down by Chemical (Hazard Information and Packaging) Regulations 1993.

FM-200® Discharge of 95% of agent must be achieved within 10 seconds

FM-200® is a gas at ambient pressure and temperature[vapour pressure 4.5bar]

FM-200® is pumped into welded steel cylinders at vapour pressure, ensuring the agent is in liquid phase.

The cylinder is then super-pressurised with Nitrogen to operating pressure [25bar]

FM-200® is discharged as liquid from the pressurised container and vaporises at nozzle.

FM 200 PHYSICAL AND CHEMICAL PROPERTIES

FM-200® Natural, non-toxic and efficient this risk specific agent is a

fine spray mist that offers effective protection without the deluge

and damage of traditional water based systems.

FM-200® is only harmful in high concentrations

FM-200® is the clean agent protection for a range of sensitive

applications, many where people are involved.

FM-200® does not deplete stratospheric ozone.

FM-200® is stored as a liquid in steel containers and super-

pressurized with nitrogen to 360psig (2482 kPa) to increase its

discharge flow characteristics

system operation steps Activation of any detector on either circuit shall;

1. Illuminate “ALARM” on FECP2. Energize Bell (1st Stage Alarm)3. Send alarm signal to Main Fire Alarm Control Panel.4. Shut down HVAC

Subsequent operation of a “Cross-Zoned” detector shall;1. Illuminate “pre-descharge” on FECP2. Activate Strobe/Horn (2nd Stage Alarm Sounder)3. Initialize discharge delay “Evacuation Timer” 30s.4. Enable system abort sequence5. After preset time delay, release agent circuit activated. FM200 is

Released. 6. Activate discharge strobe

FM 200 HYDRAULIC CALCULATION

W=(v/s) * ((c/(100-c)) W = weight of clean agent V = net volume of hazard

V= AREA * HEIGHT S =specific volume s.h agent S : NFPA 2001 –Appendix A- Table A-3-5.1C = concentration of agentC : RANGE (7% TO 9% ) TAKE IT 7%T= temperature of place T : Different according to application condition

Solved example illustrate how to determine amount of fm200 and distribution of piping

FM 200 HYDRAULIC CALCULATION

Control room area 10m*5m with height 3m and its temperature 30CCalculated total weight of fm200 and draw net work with sizing and number of nozzle ?

Solution Step one :write the law of weight W=(v/s) * ((c/(100-c))

Step two : cal. Volume & V= 10*5*3=150m3Step three : get the s from NFPA2001 from Table A-3-5.1

match with T= 30C s= 0.1425 (m3/kg)

Step four : put c= 7%Then , w= (150/0.1425)*(7/93)=79.2 kg of fm200
