Power Fault
If the detector LED indicator is OFF or flashing then there may be a power supply fault, as shown
below:
Figure 10: Power Supply Diagnostic Chart
When investigating power supply faults, it is important to check that all voltages are within the
detectors operating range (18V to 32V) under full load conditions as the voltages measured under
no load conditions can be misleading.
