(1) the fire detection systems monitor airplane components for overheat, fire or smoke condition. Engine and APU fire and overheat indication occurs on the P8 and P7 panels. Wing and body duct overheat warning occurs on the P5 and P7 panels. Lavatory smoke detection indication is an optional feature that is available. Indication can occur at the lavatory location and or on the P5 panel.

火警探测系统监控飞机组件的过热、失火或烟雾等情况。发动机和 APU过热和失火指示出现在 P8或 P7板上。机翼和机身管道过热警告出现在 P5或 P7板上。厕所烟雾探测指示是一个可选装配件。指示能够出现在厕所位置或 P5板上。

(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.

发动机失火和过热信号探测由安装在发动机周围的探测元件提供。发动机和 APU火警探测组件 M279，安装在电子设备舱，用于判断是否有失火或过热情况发生。当在飞机蒙皮探测到火警信号时，音响警告设备 M315将给出一个警告铃声。两台发动机灭火瓶安装在主轮舱左下方后角处，并从□□处释放。

(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.
APU探测器只感应火警信号。传感器的监控由 M279完成。指示出现在P28板在主轮舱和 FLIGHT DECK。 APU灭火瓶后压力隔板上，并通过P28板或 FLIGH DECK释放。
(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.

轮舱火警探测由安装在轮舱天花板上的探测元件来提供。探测器提供信号给安装在电子设备舱的 M237组件。指示信号出现在 P7和 P8板上，警告铃声由 M315组件提供。

(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.

机翼和机身过热探测系统监控增压系统有无渗漏。探测系统分为左右两部分。探测器提供信号给 M237组件。过热指示信号出现在 P5和 P7板上。
