ENGINE FIRE EXTINGUISHERS
Two fire extinguisher containers are
located on the aft side of the baggage
compartment rear bulkhead. The No.1 and
No.2 bottles have discharge tubes
connected to both engine compartments.
Each container holds approximately 0.983
liters (60 cubic inches) of Halon charged
with 4,134 kPa (600 psi) nitrogen.
Electrically activated squibs permit each
bottles' contents to be directed into either
engine compartment. In the event of an
engine fire warning indication, ARMING
that engines' system will automatically
close the selected engines'
fuel shut-off
valve and bleed air valve, and connect the
AGENT RELEASE switch to both bottles'
discharge valve for that engine. Either or
both bottles may then be discharged to the
affected engine compartment. A
transparent port on either side of the aft
fuselage allows inspection of the bottles
pressure gages.
