Question 1

ENGINE FIRE DETECTION SYSTEM works…

Answer 1

Each engine is equipped with a fire detection system which consists of two identical detection loops (A and B) mounted in parallel and a fire detection control unit. The detection principle is based on the variation of resistance and capacitance of the detection cable (fire signal). If there is only a change in resistance, associated loop will be declared failed by the fire detection control unit (fault signal). ENG FIRE alert is displayed on EWD in case of fire signal detected by both loops A and B or fire signal detected by one of the 2 loops if the other one is selected OFF.

• Se o LOOP estiver FAULT, deve desligar após 400fts para que o outro LOOP possa funcionar. (Simulador)
