1. INTRODUCTION
The aircraft fire protection system consists of the following separate subsystems:
S Fire and overheat detection
S Fire extinguishing.
The fire protection system provides detection and extinguishing of a fire in the engine
nacelles, the auxiliary power unit (APU) compartment and the cargo compartment. An
independent system is provided for fire detection and extinguishing in the lavatory. A
detection system is also provided for the main landing gear wheel wells.
The fire protection system provides detection and extinguishing of a fire in the engine
nacelles and the auxiliary power unit (APU) compartment. The main landing gear wheel
wells are provided with fire detection only. An independent system is provided for fire
detection and extinguishing in the lavatory. <0057>
Indications to alert the crew to fire, smoke and overheat conditions as well as fire protection
system health are provided by the EICAS displays and panel lights.
