Defect/Fault Mode
The main control module constantly monitors the system status and upon detection
of a fault condition, the defect LED illuminates and the panel sounder sounds one
short beep every 3 seconds.
The panel sounder can be silenced by pressing the acknowledge button “Ack”. This
will silence the fault buzzer. However, should a new fault occurs, the sounder will
sound again.
Once the fault or defect has been restored, the buzzer will silence automatically and
the defect light will turn off.
The illumination and number of flashes of the defect and power On LED’s is
dependent on the type of fault as shown in Table 3 below.
