5 Loop Installation Tips

A . CABLE SPECIFICATIONS FOR LOOP AND FEEDER
• 16 AWG (1.5mm²) cross section area ;
• Multi-strand cable ;
• Insulation material : PVC or Silicone ;
• For the feeder cable, the wire must be twisted at least 15 times per yard for each cable.
• Feeder for long runs used for foil screened cable is recommended (earth at equipment end only)
• The feeder cable must be firmly fixed to avoid any false detection (max length: 330 ft. / 100m).
• Waterproof cable junction box is required.
B. LOOP GEOMETRY
Ea
Eb
C. NUMBER OF LOOP TURNS
• Measure the length (L) and width (Ea) of one loop. Multiply these numbers together to determine the loop surface area.
• For example: If L=10 ft, Ea= 3 ft, then the area = 30 ft
If L=2m, Ea=1m, then the area = 2 m
WARNING: FOR CONFORMITY REASONS, IN ANY INSTALLATION, THE LOOP SURFACE MULTIPLIED BY THE NUMBER OF
TURNS SHOULD NOT EXCEED 215 SQUARE FEET OR 20 SQUARE METERS.

• When two adjacent loops are connected to a dual channel
sensor, it is possible for these loops to share a common
slot, if so required. As the channels are multiplexed, no
interference will occur.
• Avoid large loops or long feeder (max 330 ft. / 100 m),
or else the sensitivity will be affected.
