7.9.9 FIRE DETECTION SYSTEM
The fire detection system in the DA 42 NG consists of an overheat detector in the hot
area of each engine. In case of an increase of the engine compartment temperature above
250 °C (480 °F) the overheat detector closes the electric circuit and a warning message
appears in the annunciation window of the G1000 PFD.
To test the fire detectors (refer to Section 4A.6.1 - PREFLIGHT INSPECTION) push the
test button located next to the gear selector switch. An aural alert and the fire warning
message for the LH and RH engine should appear in the annunciation window of the
G1000 PFD.
CAUTION
If the warning does not appear, an unscheduled maintenance
is necessary.
