Wiring the Pathfinder Expansion Module
General Guidelines for Wiring the Expansion Module on a Vehicle
HIGH CURRENT ARCING: Do not connect this system to the vehicle battery
until ALL other electrical connections are made and you have verified that no
shorts exist. High current conductors can cause hazardous sparks or burning
wire, resulting in electrical fires.
DRILLING PRECAUTIONS: When drilling into a vehicle structure, ensure that
both sides of the surface are clear of anything that could be damaged. All
drilled holes should be deburred and all sharp edges should be smoothed.
All wires going through drilled holes should be protected by a grommet
or convolute/split-loom tubing. Additionally, all exterior drilled holes must
be sealed with Motorcraft seam sealer T-A-2-B or equivalent to prevent the
potential exposure to carbon monoxide or other potentially harmful fumes.
Failure to observe this warning could cause serious injury or death.
Before permanently installing the Pathfinder Siren and Expansion Module system,
plan all wire routings and select the mounting locations for the siren amplifier and
Expansion module. Read and understand all instructions included with related
equipment before installing it. Ensure that all wiring is protected from damage
during normal operation of the vehicle and away from any sharp edges and
screws. Splice joints should be soldered or crimped with butt connectors, and
properly insulated. Splice joints that will be exposed to the elements should be
adequately sealed and insulated. All wires that are extended should not be lesser
gauges than their original mating wires. Make sure that connections are easily
accessible for assembly and service.
Overview of the Pathfinder Connections
To prepare the vehicle for connecting the Convergence Network system:
1.
After planning where to route the wires and cables for the system components
— such as Federal Signal warning lights, directional lights, and speakers — drill
the holes for the wiring. Smooth, deburr, and insert a grommet in the holes.
2.
Mount the system components according to the instructions included with each
product.
The next sections describe how to connect and wire each system component to
the Expansion Module.
Convergence Network Ports
There are three “plug and play” serial ports that communicate on the Federal
Signal Convergence Network. Federal Signal Convergence Network devices
include exterior mount light bar, interior mount ILS systems, and remote keypads.
