DMS
MAGNETIC VEHICLE DETECTOR
High precision magnetic detector to which a loop is connected to detect the presence of vehicles (metal masses) in a pre-determined area. Main applications:
- Vehicle entry/exit control to provide access to garage doors, gates, barriers, etc.
- Detection of vehicles near to automatic traffic light installations.
- Detection of metal masses from a pre-determined area.

INSTALLATION
LOOP INSTALLATION
- Make a rectangular chasing groove in the ground according to the table of dimensions relating to the
number of loops, the maximum depth of which must be 5cm.
- Insert the flexible braided 1.5 or 2mm2 section wiring, surrounding the inside of the rectangle until the
correct no. of loops (turns) has been completed.
- Braid the two outgoing ends of wiring to terminals 10 and 11 of the magnetic detector.
- Fill the chasing where the loops are located with fast-drying cement in a compact and firm manner so
that they cannot be moved, either through vibrations or through the cracking of the covering itself.
