of

sq.mm
(awg

-

preferably
multi-stranded.
Note:-
High bed vehicles require larger loops.
Recommended depth to top of loop cable 25-50mm. (Maximum depth 65mm) Loop slot
MUST
be sealed after cable has been installed and tested.
Use a flexible, weather proof sealant (i.e. Hot bitumen, Rubberised bitumen sealant).
CAUTION!
Never use cement / concrete, etc...
The feeder cable
MUST
be
twisted
a
minimum
10
times
per
meter
&
can
be
up
to
250m
long.
The loop must be placed at least 5m away from high tension cables and at least 1m away from low tension cables. If the loop is placed in an area with reinforcing iron (typically a concrete floor), the loop must be placed at least 50mm above the reinforcement. If the detector is used for detecting high vehicles (lorries etc.) use only one loop for each
detector
, otherwise it is possible to connect two loops to a single detector
. Series coupling
the loops will give the largest sensitivity
, parallel coupling gives the fastest reaction.
