5.9 Optional Vehicle Detector Installation in Drive-Thru Lane
If a vehicle detector loop will be used, it should have already been installed. If another type
vehicle detector will be used, install it according to its own installation instructions.
Connect it to the Bridge according to Figure 21, pg. 55. Note that the connections are different
for internal and external type vehicle detectors. Be certain the wires are fully inserted into
each connector plug to prevent shorting the wires.
1. Route a cable from the vehicle detector to the Bridge.
2. Remove 4 inches of outer insulation from the end of the cable at the Bridge, and strip
approximately ¼ inch of insulation from each of the color-coded wires coming from the cables.
3. If an internal vehicle detector is used, route the cable from the underground loop to Base 1,
and connect it to the TB1 terminal block on the Vehicle Detector Board, as shown in Figure 21,
pg. 55.
If an external vehicle detector is used, route the cable from the underground loop to the
external detector. Wire the detector output to pins 1 and 2 of the J5 connector on the Bridge
circuit board, as shown in Figure 19, pg. 53.
