Detector position and installation

 Install the detector in a weatherproof housing.

 The detector should be as close to the sensing loop as possible.

 The detector should always be installed away from strong magnetic fields.

 Avoid running high voltage wires near the loop detectors.

 Do not install the detector on vibrating objects.

 When the control box is installed within 10 metres of the loop, normal wires can be used to connect the

control box to the loop. More than 10 metres requires the use of a 2 core shielded cable. Do not exceed

30 metres distance between control box and loop.
