Systems with a fault in one loop reconfigure for single loop operation. If the operable loop senses a fire or overheat condition, the related fire warning or overheat caution activates. Sample air from throughout each compartment is drawn through the detectors by center bleed duct air. Pushing the FWD or AFT CARGO FIRE ARM Switches arms cargo fire extinguishers, configures equipment cooling to override mode and turns off airflow and heat into forward compartment, turns off pack 3 and all fans. Fault monitoring of the cargo smoke detectors only occurs during a system test.
Wheel well:- Each main gear wheel well has a single loop detector. - The wheel well fire detector loop and the bleed duct leak detector loops are tested only during the manually initiated test. Crew Rest Smoke Detection:- Smoke detectors are installed in crew rest areas. An aural warning sounds in the crew rest compartment when smoke is detected in that compartment. Lavatory Smoke Detection:- Smoke detectors are installed in the lavatories. An aural warning sounds in a lavatory when smoke is detected in that lavatory. - An automatic fire extinguisher is located in the waste compartment in each lavatory. Purser Station Smoke Detection:- A smoke detector is installed in the Purser Station. An aural warning sounds in the Purser Station when smoke is detected in that compartment.

B747-400 System Quick Review Doors • Except No. (3) door slides are not usable as a life raft and should not be used during ditching. • Each slide/raft contains a canopy, a survival kit and a hand pump. • An escape strap located above and forward of the overwing exit. • If both body landing gear are not extending the No. (1) door escape slide are unusable. • The door is power assist open when unlatched with mode select lever in the AUTO position. • Unlatching the door from outside automatically moves the mode select lever to MANUAL disabling the evacuation slide/raft and the power assist system. • If a door FWD/AFT cargo caution occur in flight, cabin differential pressure must be reduced to minimize the risk of door separation. Other doors not required to depressurize the cabin. If differential pressure is above (3) psi, it is not possible to open the U/D door from inside.
