Power printed circuit board (PCB) receives 24 VDC input power from an external power source and
detector heads directly while 50 VDC provides bias voltage for the IDD detectors. Both 15 VDC and 50
provides 5 VDC, 12 VDC, 15 VDC, & 50 VDC power for various circuits. The 15 VDC supply, powers IDD
microprocessor for signal processing. Microprocessor runs FFT algorithm to provide signal intensity at
tuning parameters from memory. When the count value exceeds the corresponding value from memory,

requirements.
