2. LED display or other TV screens, switching power supplies or neon displays must
be kept at least 2m away from the antenna coils.
3. Maximum cable length between the antennas and the Control Unit is 10m. Do not
extend this cable, even with the same type of cable. If the cable is cut too short,
do not attempt to rejoin the two ends since this will degrade the shielding
performance of the cable.
Risk of electric shock! Conduit is required for the cable between the
antenna and the Control Unit.
To avoid adding significant time and cost to the in-floor installation,
check the detection performance and label detection height at the exact
installation site. Do this before cutting the floor and do this again before
pouring the concrete!
4. Install the antennas inside the store as close to the entrance/exit doors as
possible, taking enough distance to metal structures and potential noise sources
into consideration.
5. Use the supplied connector piece to create the required distance between the two
transceiver coils.
6. Tiles are placed underneath the antennas and the antennas are elevated using
spacers to improve performance:
a. Tiles are placed at the bottom of the cavity in the screed. No metal rebar or
wire mesh may be present within 10 cm of the sides of the antennas.
b. Antennas are typically between 3 cm and 5 cm below the surface of the
screed for floors subject to normal duty. Floors subject to light duty (foot traffic
and shopping trolleys only) high psi mortar/concrete thickness above the
antennas and conduit may be as little as 1 cm. Make sure to consult this with
a certified installer/contractor.
7. For conduit runs use rigid or plastic conduit. Some local codes require rigid conduit
instead of plastic for concrete burial.
8. Use a separate conduit for each antenna. Conduit runs must be a minimum of 20
cm from the antennas and may not cross above or below the antennas. It must be
routed around the perimeter.
9. All conduit fittings must be rain/concrete tight. Wrap threads with four turns of
Teflon pipe tape.
10. Minimize underground conduit couplings to prevent moisture intrusion.
11. Avoid walking on antenna cables during installation.
12. Use non-metallic, non-shrink mortar/concrete. Make sure to consult this with a
certified installer/contractor.
13. Mortar cure time depends on the mix and temperature of the mortar ingredients.
