96.13.3 Engine Fire Extinguisher System
NOTE
S/Ns 30817, 30931, 30687, 30576
and 30599 are fitted with an ENG
FIRE “T” handle. All S/Ns except
30817, 30931, 30687, 30576 and
30599 are fitted with ENG FIRE
and FIRE EXTING switch-lights.
The engine fire extinguisher system consists of a
fire extinguisher discharge switch, located on the
instrument panel above the fire handle or FIRE
EXTING switch-lights located on the instrument
panel at each crew station, and a fire extinguisher
cartridge located on the left side of the service
deck aft of the engine.
When a fire occurs in the engine compartment, the
fire detector amplifier (Z4) causes the FIRE 1
PULL handle or the ENG FIRE switch-light to
illuminate. In the event that fire extinguishing
action is required, pulling the FIRE 1 PULL handle
or lifting either safetied cover and pressing the
ENG FIRE switch-light will arm the squib on the
extinguisher bottle and illuminate the FIRE
EXTING switch-lights. Actuating the FIRE EXT
switch or pressing either illuminated FIRE EXTING
switch-light will discharge the extinguisher bottle.
