5.4 FAULT DIAGNOSIS
If the panel has detected a fault on the system the General Fault LED will be illuminated and the internal fault
buzzer will sound. Secondary LEDs will also be illuminated depending on the location of the fault.
Pressing and holding the ENTER button will reveal more detailed
information about the location and type of fault.
This function will not work if the panel is in a fire condition. If no faults
exist pressing the ENTER button will have no effect.
This function is only operational when controls are not active.
The following table shows details of the indications in fault diagnosis mode:
