Analysis:

Engine fire loop senses a fire. If the lights in the FIRE handle and FUEL CONTROL switch are illuminated, the fire warning is valid. If the lights are not illuminated, you may have a faulty fire detection loop.

Procedures:

[G450 AFM, § 4-10-20]

    In the event an engine fire warning is annunciated, proceed as follows:

  1. Airplane ... STOP
  2. PARK / EMERG BRAKE ... SET
  3. Affected Engine ... IDENTIFIED
  4. Both Power Levers ... IDLE
  5. Both FUEL CONTROL Switches ... OFF
  6. Affected Engine FIRE Handle ... PULL
  7. If fire warning indications are no longer present:

  8. FIRE TEST / FIRE DETECTION Test ... PERFORM
  9. If fire test / fire detection tests are satisfactory, proceed to Step 11. if fire test / fire detection tests are not satisfactory or fire warning indication still present:

  10. Affected Engine FIRE Handle ... ROTATE TO DISCH 1 (TURN TO EXTREME POSITION)
  11. NOTE: When it is necessary to discharge by a fire bottle, ALWAYS use DISCH 1 first. This will discharge extinguishing agent from the RIGHT fire bottle, preserving the LEFT fire bottle for APU protection. Only the LEFT fire bottle can be used for APU protection.

    If fire warning indications are no longer present:

  12. FIRE TEST / FIRE DETECTION Tests ... PERFORM
  13. If fire test / fire detection tests are satisfactory, proceed to Step 11. If fire test / fire detection tests are not satisfactory, or if fire warning indications remain present for thirty (30) seconds:

  14. Affected Engine FIRE Handle ... ROTATE TO DISCH 2 (TURN TO EXTREME POSITION)
  15. If fire test / fire detection tests are satisfactory, or after discharge of fire bottle(s):

  16. APU MASTER ... OFF
  17. LEFT / RIGHT MAIN BATTERIES ... OFF
  18. NOTE: When the Main Batteries are selected OFF, the Emergency Power system will activate. If emergency lighting is not required for evacuation, select the Emergency Power Off switch to OFF before selecting the Main Batteries to OFF.

  19. Airplane ... EVACUATE
