INSTALLATION AND OPERATION INSTRUCTIONS — FENCE PROTECTION SYSTEMS
Microwave Gate Protection
The
Magal-Senstar
MPS-4100 microwave system provides coverage of the area around a gate
while allowing the gate to move freely. See Figure 44. The FPS transducer cable can terminate at the
end of a zone on either side of the gate or nonsensitive cable can be spliced and run underground in
conduit to continue the zone.
Please see the MPS-4100 Installation and Operation Manual for installation information.
Transducer Cable Connections
The pre-amp transducer cable connections are very important to the operation of the sensor system.
Before proceeding with transducer cable terminations, the transducer cable should be completely
installed and terminated in the zone and the transducer cable extended through the conduit and/or
the pre-amp cable glands into the pre-amp enclosure. To connect the transducer cable to the pre-amp,
proceed as follows:
Step 1:
Strip outer insulation of the transducer cable 1 inch from the end.
Step 2: Open the entry gland by rotating the outer shell one full turn counter clockwise.
Step 3:
Pull transducer cable through to the inside of the processor enclosure.
Step 4:
Pull braided shielding back 3/4 inch from outer conductor and twist.
Step 5:
Strip center conductor insulation back 1/4 inch from the end.
Step 6. Attach the center conductor and the braid to the screw terminal located on the lower edge of
the pre-amp board as shown in Figure 48. Be sure to separate shield and center conductor at
terminal block to avoid noise in audio. If you are installing a double run sensor cable, attach
the other end of the sensor cable to the 1 meg ohm terminations as shown in Figure 48.

GATE
NOTE:
FPS is stopped 1-2 panels from gate to
eliminate nuisance alarms when gate
moves.
Microwave overlap protects
the area where FPS does
not sense.
