GENERAL
A Fire Detection and Extinguishing (FIDEEX) system with fault discrimination is installed with fire
detectors located in each engine nacelle and in the APU compartment.
The FIDEEX system interfaces with numerous airplane equipment and provides the following
capabilities:
· Monitor zones for fire/overheat/smoke events and FIDEEX system health and status.
· Automatic detection and reporting of fire events for each of the two power plants and the
Auxiliary Power Unit (APU).
· Fire extinguishing for each of the power plant and APU upon receipt of pilot initiated arming
and discharging commands.
· Automatic detection and reporting of overheat events for the two Main Wheel Wells (MWWs).
· Automatic detection and reporting of smoke events for each of the lavatories (fwd/aft),
baggage compartment, up to four cabin closets (requires installation of optional smoke
detectors) and avionics bay.

FLIGHT COMPARTMENT FIRE WARNING
The fire protection system provides the means to detect and extinguish a fire in the engine nacelles
and in the Auxiliary Power Unit (APU) compartment. Engine/APU fire warning is provided by:
· MASTER warning lights (2).
· Aural warning.
· EICAS messages.
· Three red warning lights (one for each engine nacelle and one for the APU compartment),
installed in the flight compartment fire handles.
Both the detection systems and extinguishing systems permit testing and/or monitoring for system
faults from the flight compartment. A fire warning and extinguisher pre−flight test of the system is
provided in the flight compartment.
FIRE DETECTING SYSTEM
An overheat detection system, installed in the pylon area for each engine, permits the flight crew to
monitor any overheat condition in this area. A similar overheat detection system is installed in each
main landing gear wheel well.
WHEEL WELL OVERHEAT WARNING
An element in the wheel well area warns of an overheat condition in either of the main wheel wells.
