Question 1

EMERGENCY EXIT LIGHTS Switch

• 3 position -

OFF

ARMED

ON

With the emergency exit lights in the armed position, what would cause the emergency lights to come on automatically? (1sp)

Answer 1

[1sp - comes on automatically if we lose DC Bus 1 (practical note - remember that before you turn off the battery switch, that the EEL switch is OFF. Because once you turn off the Batt switch you will lose DC Bus 1 and all the lights will go on.)]

OFF:

ARMED: (guarded)

• emergency lights come on when
  
  • DC Bus 1 loses power (<12 v)
