FIRE PROTECTION
ENGINE FIRE EXTINGUISHING SYSTEM
Engine fire extinguishant is supplied from two dual-head, single-shot extinguisher bottles located in the
rear equipment bay. The extinguishant is distributed from the bottles by tubing connected to twin high-
rate discharge nozzles mounted one on each engine pylon wall and located to discharge into the
associated engine bay.
Each extinguisher, via the dual extinguisher head, is piped to both engines which allows either one shot
of extinguishant per engine or two shots of extinguishant to a single engine, as necessary.
OPERATION
Discharge of each bottle is achieved by the firing of electrically operated cartridge units mounted in the
dual head of the bottles. Firing of the cartridges is controlled by two ENG EXT baulked selector
switches, one for each engine.
When either switch is selected to SHOT 1 or SHOT 2 the relevant cartridge fires and one bottle is
completely discharged into the appropriate engine. At the same time, adjacent to the selector switch,
an associated EXT FIRED transparent indicator fuse turns red.
NOTE: Figure 2 shows a fire occurred in No. 1 engine and extinguisher bottle 1 has been used
(shot 1).
The second bottle is still available for use, either in No. 1 engine (shot 2) or in No. 2 engine
(shot 1) should the need arise.
Two pressure relief discharge indicators, located on the fuselage below the left engine pylon, are
connected one to each bottle and are visible for walk around inspections. The indicators normally
display a green disc.
In the event of excessive pressure in the bottle, a safety disc ruptures to release the contents. The
released extinguishant flows to the discharge indicator and blows out the green disc to reveal a bright
red interior and the discharged bottle must be replaced before the next flight.
REAR EQUIPMENT BAY OVERHEAT
An overheat condition in the rear equipment bay is detected by six thermally-operated switches and
indicated by a single REAR BAY OVHT annunciator on the MWS panel.
Operation of one or more of the switches connects a supply to the annunciator and activates the MWS
master warning lamps which flash until acknowledged.
NOTE: The fire warning bell does not sound.
BAGGAGE BAY and TOILET SMOKE (if installed)
The airplane normally has three smoke detectors installed. The smoke detectors are located in the
forward baggage compartment, the aft baggage compartment and the toilet vanity.
If smoke is detected, a red REAR BAGG SMOKE annunciator on the MWS panel illuminates and the
MWS master warning lights flash until acknowledged.
NOTE: The fire warning bell does not sound.
