1.5 Safety precautions
This Loop Detector must not be used in applications where personal safety depends on the function of the Loop
Detector.
Installation and use must be carried out by trained technical personnel with basic electrical installation knowledge.
The installer is responsible for correct installation according to local safety regulations and must ensure that a
defective Loop Detector will not result in any hazard to people or equipment. If the Loop Detector is defective, it
must be replaced and secured against unauthorized use.
1.3 Who should use this documentation
This manual contains important information regarding installation and must be read and completely
understood by specialized personnel dealing with these kinds of devices.
We highly recommend that you read the manual carefully before installing the Loop Detector. Please save
the manual for future use. The installation manual is intended solely for qualified technical personnel.
1.4 Use of the product
The Loop Detector is primarily used to detect vehicles such as cars, trucks, buses and others.
A loop in the ground is required for the Loop Detector to detect any vehicles above the loop. The device
works on the same principle of an inductive sensor; utilizing the phenomenon of eddy current. When a
metal target/vehicle approaches on top of the loop, the magnetic field generated by the loop interacts with
the target and makes the Loop Detector to change its output.
The Loop Detector can be used at carpark barriers, bollards, gates, toll gantries and many other door
access applications.
1.1 Description
