Data/audio connections
A typical FPS-5 installation requires a pair of multimode fibers looped through all FPS-5 and SAFT
processors (up to 30 transponders per fiber optic loop) and returning to the MXF-7500. This provides
redundant paths for data and audio information (see Figures 13 and 23).
A typical FPS-2-2 installation requires two twisted shielded pairs from the back of the MX-7000 to each
processor in the field (up to 10 per loop) (see Figures 6 and 22).
Power connections
All field equipment is powered either locally or by way of a separate centralized power supply. The wiring
distances required by outdoor perimeter protection systems can cause a significant voltage drop between
a central power supply and the distributed processors. Each FPS-2-2 processor requires 30 mA at 12-16
VDC and each FPS-5 and SAFT processor requires approximately 130 mA at 12-24 VDC. The central
power supply and power cables must be sized accordingly.
NOTE: Use a separate power supply (not the MX unit) to power fiber optic communicating
transponders.
