 ENGINE FIRE DETECTION SYSTEM - ADJUSTMENT/TEST
______________________________________________
 1.  General_______
 A.  The engine fire detection system monitors the engine nacelle temperature for fire and overheat conditions. Dual-loop fire/overheat detectors are in each engine area.
 B.  The system uses power from the 28-volt dc battery bus. The circuit breakers are on the P6 panel.
 C.  The engine fire detection system components are: the fire detectors, the engine and APU fire detection accessory unit, and the engine and APU fire control panel.
 D.  There are two tasks in this section:
 (1)  
Operational Test of the Engine Fire Detection System

 (a)  The operational test is done in a minimum of time, and uses equipment installed on the airplane to make sure that the system will operate correctly.

 (2)  
System Test of the Engine Fire Detection System.

 (a)  The system test is a full check of the engine fire-detection system.
