Option - Dual cargo fire extinguisher bottles.
Two fire extinguisher bottles are installed in the air conditioning mix bay on the
forward wing spar. Detection of a fire in either the forward or aft compartment will
cause the FWD or AFT cargo fire warning light to illuminate. The extinguishers
are armed by pushing the appropriate cargo fire ARMED switch. Once armed, the
first bottle is discharged by pushing the cargo fire DISCH switch. This results in
the total discharge of the first bottle contents into the selected compartment. The
second bottle discharge is metered to discharge at a reduced flow into the
selected compartment. Discharge of the second bottle may be disabled if the
system is disarmed. The cargo fire DISCH light illuminates when a bottle is
discharged. It may take up to 30 seconds for the light to illuminate. On landing, if
the first bottle was discharged and the system remains armed, the second bottle
is inhibited.
