FIRE EXTINGUISHER
FIRE EXTINGUISHERS
The fire extinguishers consist of steel cylinders filled with HaIon 1301 and equipped
with a quick-release valve assembly.
The cylinders contain HaIon fire suppressant pressurized with dry nitrogen for use on
hydrocarbon fuel fires only.
The crew AFES has four or six automatic fire extinguishers, depending on the vehicle
configuration has shown above.
Crew AFES fire extinguishers discharge automatically when the SECA receives an
electrical pulse from an OFSA unit, or manually when a crew member operates the
MANUAL ELECTRIC DISCHARGE toggle switch on the crew T/A panel.
When the crew AFES activates, the ventilator blower automatically turns to the ex-
haust mode 8 seconds after extinguisher discharge, but the crew must open the ex-
haust blower vent (p. 2-193).
