a. A fire warning lights Press-To-Test switch.
b. Four red fire warning lights.
c. Four covered fire extinguisher pushbuttons.
d. Four feathering buttons with integral amber fire warning lights.
2. When the temperature exceeds 210°C with any one of the flame
switches operating, both the red and amber fire warning lights illuminate
on the Pilot’s panel. When the fire warning lights are illuminated, the
extinguishing system operates automatically when the associated
feathering button is pressed. The extinguisher bottle connected to the
carburettor air intake system is discharged immediately. The second
bottle, connected to the spray pipes, discharges after eight seconds if
the propeller is feathered. If the propeller feathers after eight seconds
but before nineteen seconds, the second bottle fires as the feathering
button springs out. After nineteen seconds the second bottle discharges
even if the propeller has not feathered
3. In addition to operation by the feathering buttons, the extinguishers
may be operated directly by pressing the fire extinguisher pushbuttons
or operation of the inertia switches (see para 8). If a fire is observed and
the fire warning lights do not illuminate, the fire extinguishers can only be
operated by the pushbuttons, both bottles discharging simultaneously.
Pre-Flight Testing
4. Press the Press-To-Test switch and check all eight fire warning lights
illuminate.
5. Visually inspect the inboard fire bottles in the wheel wells and ensure
the operating pins do not protrude.
Hand Fire Extinguishers
6. Six hand held BCF fire extinguishers are stowed as follows:
a. Just forward of the tail gunner’s position on the port side of the
fuselage.
