4. Avoid unnecessary long cables. Run the power supply cables in a direct line to
the EAS antennas. Never run power supply cables vertically up the wall within
one meter distance of the antennas (never around the entrance/exit doorframe).
5. By default the shielding of shielded cables is not connected to the electronic
boards or antenna frames if not stated otherwise in the Connections chapter of
this manual. Only in case of high noise and bad performance it is advised to
experiment with connecting the shielding to see if these connections will improve
the performance.
6. Do not connect more than three (3) transceiver antennas to one (1) power
supply.
7. Metal framed doors may never swing between the EAS antennas, as this will
distort the energy field of the system in such a way that it might result in high
noise, poor detection and potential false alarms.
8. Do not connect unshielded and untwisted cables to the I/O’s as this might affect
the performance of the EAS system in a negative way.
9. Do not attach any equipment or devices to the antenna frames.
10. Take into account that when using a laptop within two meters of the antennas,
the laptop or its power supply might create noise signals. Use a longer cable to
create more distance between the laptop and the EAS system.
11. Do not install antennas with less than 50cm distance between them as this will
have a negative effect on the performance.
12. Where possible, use conduits to run the cables through. Make sure to use
conduits with a sufficient diameter. In some situations you might need to run 3
cables through the conduit. The power supply cable is ø5mm and the average
FTP cable is ø6mm. When for example 2 power supply cables and 1 FTP cable
need to be run through one conduit then this conduit must have a diameter of at
least 20mm.
13. A cable tester is required. The various devices are interconnected through FTP
cables. Make sure to test the cables prior to plugging them into the RJ-45
connectors on the devices, especially if you’re not using pre-assembled cables!
14. It is recommended to use steel anchors (e.g. SPIT EPOMAX resin with zinc
coated steel rods) to mount the antenna to the floor. Do not use screws and
plugs, as this will not keep the antenna properly fixated to the floor, resulting in
tilting antennas and potential loss of performance.
