Optional External Vehicle Detector Installation; Optional Hme Vehicle Detector Board (Vdb) Installation - HME Wireless 6000 Installation Instructions Manual

2.3.4

Optional External Vehicle Detector Installation

If an external type vehicle detector will be used, install it according to its own installation
instructions. Connect the vehicle detector to the base station according to the appropriate
wiring diagram on pages 25 — 28. Note that the connections are different for internal and
external type vehicle detectors.
•
If an internal vehicle detector is used, route a cable from the underground loop to the
TB1 terminal block on the Vehicle Detector Board.
•
If an external vehicle detector is used, route a cable from its output to the J30
connector on the audio board in the Wireless 6000 base station.
•
Remove 4 inches (100 mm) of outer insulation from the end of the cable at the base
station, and strip approximately ¼ inch (6 mm) of insulation from each of the color
coded wires coming from the cables.
•
Connect the color-coded wires to connector J30, pins 3 and 5 for negative vehicle
detection according to the wiring diagrams on pages 25 — 28. Be certain the wires are
fully inserted into each connector plug to prevent shorting the wires.
2.3.5

Optional HME Vehicle Detector Board (VDB) Installation

To install an HME VDB in the base station, follow the instructions below.
•
Open the base station by pushing the latches on the front cover and VERY CAREFULLY
guiding the cover downward.
•
Carefully position the three holes in the VDB over the three plastic standoffs at the upper
right side, inside the base station as shown in Figure 10. Press on the VDB until the tips
of the three standoffs snap through the holes in the board.
•
Connect the cable assembly enclosed with the VDB to the P1 connector on the vehicle
detector board, and the other end to the J6 connector near the upper, right corner of the
switcher board. If there is no switcher board, connect the cable assembly to the P1
connector on the vehicle detector board, and the other end to the J10 connector at the
right end of the audio circuit board as shown in Figures 20 — 23 on pages 25 — 28.
•
Close the cover on the base station, and lock it by pushing until it latches.
