CEP BIT FAULT CODES
NOTE
The following describes types of fault status displayed by CEP after a BIT has been
completed. These events will be recorded in CEP History.
1.
Engine Compartment Sensor LED will illuminate when a sensor fails a BIT. Even though a BIT reports a
faulty sensor, the system will remain functional, including recognition of a valid fire signal from the faulty
sensor (Table 1).
2.
CEP LED will illuminate in response to an internal failure.
3.
The SYSTEM ON LED will display a repeated double blink, followed by a pause indicating battery voltage is
not at the acceptable range for AFES to function (Table 1).
4.
Fire Extinguisher Bottle LED illuminates when a fault is detected as follows:
a.
Extinguisher LED will illuminate if extinguisher has become disconnected, valve has an open circuit, or
has insufficient internal pressure.
b.
Extinguisher LED will blink if extinguisher bottle has discharged.
c.
Extinguisher LED will double blink, pause, and then repeat when extinguisher fails to discharge
when activated.
