5.4 Vehicle Control Unit Installation
This subsection describes the installation of the
3M™ Opticom™ GPS Priority Control System
Vehicle Control Unit. It also describes connecting
the radio/GPS cable from the radio/GPS unit to the
control unit and connecting the vehicle interface
harness to the control unit.
Please read and fully understand the following
precautionary paragraphs before installing the
control unit.
??
Installations may include a customer-supplied
disable switch in addition to the control unit. The
Disable feature disables the priority request when
the disable switch closes to battery negative or
positive. This feature typically uses an existing
switch that indicates the presence of conditions
deemed appropriate to disable the priority request,
such as opening the vehicle operator’s door.
??
The control unit location must be level within 15
degrees, readily accessible, and visible to the
vehicle operator. It must be level to allow the
internal compass to function.
??
The control unit must not be in the path of
airbag deployment.
??
Use care when drilling holes to avoid drilling into
undesirable locations.
1. Determine the desired location to mount the
vehicle control unit. Mark and drill two
7/32-inch holes, using the control unit
mounting bracket as a template.
2. Insert the two 10-32 x 3/4-inch cap screws
through the holes in the mounting bracket and
mounting surface. See Figure 5-4.
3. Use the two lock washers and 10-32 nuts to
secure the bracket to the vehicle.
