a
The manufacturers listing specifies the temperature range for operation.
b
W/V [agent weight requirements (kg/m
3
)] = kilograms of agent per cubic meter of protected volume to produce
indicated concentration at temperature specified.
W = (V/s) X [c/(100-c)]
c
t [temperature (°C)] = the design temperature in the hazard area
d
s [specific volume (m
3
/kg)] = specific volume of superheated FM-200 vapor can be approximated by the formula:
s = 0.1269 + 0.0005 t
where t = temperature (°C)
e
C [concentration (%)] = volumetric concentration of FM-200 in air at the temperature indicated.
