Fig 5-1 .fire protection
2 Engine fire and overheat detection is provided by detector elements located
around the engine. The Engine and APU fire detection accessory unit M279, located
in the E/E bay determines if a fire or overheat condition exists. When detected
indications occur in the flight deck an alarm bell is provided by the aural warning
devices unit M315 for a fire condition. The two engine fire extinguisher bottles are
located on the upper left aft corner of the main wheel well and are discharged from
the flight deck.

3 The APU detectors sense fire conditions only. Monitoring of the sensors is
accomplished by the M279. Indications occur on the P28 panel in the wheel well
and also in the flight deck. The APU fire bottle is located behind the aft pressure
bulkhead and is discharged either from the flight deck or P28 panel.
4 Wheel well fire detection is provided by detector elements mounted on the
wheel well ceiling. The detectors provide input to the M237 module located in the
E/E bay. Indications occur on the P7 and P8 panels and an alarm bell is provided by
the M315 module.
5 The wing and body overheat detection system exists to monitor the pneumatic
system for leaks. The detection system is divided into a left and right system.
The detectors provide input to the M237 module. Overheat indication occurs
on the P5 and P7 panels.
6 The lavatory smoke detector is located in each lavatory ,the detector will
provide a warning horn and indication at a specified smoke level. Located in each
lavatory, beneath the wash basin, is a fire extinguisher bottle which responds to
high temperature in the towel chute.

TEXT
1 The purpose of the oxygen system is to provide oxygen for the flight crew and
passengers when required. Two independent oxygen system are installed in
B737. The flight crew oxygen system is a high pressure gaseous system for
flight crew use only, this type of system is designated a "diluter demand"
system. The passenger oxygen system is a chemically-generated oxygen
system for use by passengers and cabin attendants. This type of system is
designated a "continuous flow" system.
