Above ground splices may be used providing the wire is twisted, soldered and moisture sealed. For best long term results, do not use wire nuts anywhere in the loop system. Connect to the Vehicle Detector harness by soldering.

For saw-cut installations, observe the methods recommended in Figure 7, above. The saw-cut must be to a depth of 1.5", clean and with no sharp corners. After placing the wires, it is essential that the wires be held tightly in place by a foam backing prior to pouring the sealant. THIS IS ESPECIALLY IMPORTANT WHEN FREEZING IS LIKELY. No voids should exist that will permit the collection of water that might freeze and push the loop wires out of the slot. The sealant used should not be hard setting and should be suitable for pavement material.

THE WIRE USED FOR THE LOOPS MUST BE HEAT AND WATER RESISTANT, CROSS-LINK POLYETHYLENE INSULATED. TYPE XLPE IS BEST. RHW IS O.K. DO NOT USE ANY PVC INSULATED WIRE. (PVC insulation will absorb moisture that may affect Detector operation.) WIRE SIZE SHOULD BE #16 GA. STRANDED OR LARGER.

VEHICLE DETECTOR LOOP BLANKING FOR SWING GATES

The inside loop for a swing gate installation must be located at least 4 feet outside of the arc of the gate. If it is not, the Vehicle Detector may detect the gate as it moves over the loop and cause the Gate to reopen. If the gate is large and a single leaf, the arc usually requires that the loop be a considerable distance from the closed gate position. This may not be an effective position for the loop. In this case, a “blanking” or “shadow” loop may be used.

When a Shadow Loop is necessary, connect the output of the loop detector to terminal #9 “Shadow Loop” and terminal #16 “Common”. The GS4000 circuitry will recognize a vehicle on the loop and prevent the gate from closing while the vehicle is over the Shadow Loop. When the gate is closing or opening, the GS4000 circuitry will ignore input from this loop as the gate swings over it.
