Notes:
1. Larger wires and tight connections will provide longer service life for components. For high current wires it is highly recommended
that terminal blocks or soldered connections be used with shrink tubing to protect the connections. Do not use insulation displacement
connectors (e.g., 3M Scotchlock type connectors).
2. Route wiring using grommets and sealant when passing through compartment walls. Minimize the number of splices to reduce
voltage drop. High ambient temperatures (e.g., under-hood) will signicantly reduce the current carrying capacity of wires, fuses, and
circuit breakers. All wiring should conform to the minimum wire size and other recommendations of the manufacturer and be protected
from moving parts and hot surfaces. Looms, grommets, cable ties, and similar installation hardware should be used to anchor and
protect all wiring.
3. Fuses or circuit breakers should be located as close to the power takeoff points as possible and properly sized to protect the wiring
and devices.
4. Particular attention should be paid to the location and method of making electrical connections and splices to protect these points from
corrosion and loss of conductivity.
5. Ground termination should only be made to substantial chassis components, preferably directly to the vehicle battery.
6. Circuit breakers are very sensitive to high temperatures and will “false trip” when mounted in hot environments or operated close to
their capacity.
Important!
This unit is a safety device and it must be connected to its own separate, fused power point to assure its continued operation should any
other electrical accessory fail. Do not wire in parallel with any other accessory.
Wiring Instructions:
Caution:
Disconnect the battery before wiring up the lightbar, to prevent accidental shorting, arcing and/or electrical shock.

ash pattern on each individual module can be cycled to the next ash pattern (shown in TABLE 1) by briey shorting together the 2 short
pads with a wire or the blade of a screwdriver as shown in FIGURE 5. The modules can be reset to the default ash pattern by shorting the
pads together for longer than 5 seconds. A thin layer of conformal coat may need to be scraped from the surface of the short pads if the
modules aren’t changing patterns easily.

TR Series Wiring
A TR series DuoBeam™ has a single cable with 7 colored wires. A dedicated ground wire, a dedicated power wire and ve colored control
wires which run through the main driver board.
The 16 AWG black ground wire should be connected directly to the battery. The 16 AWG red power wire requires a constant 10 to 16V(+)
power source with a customer supplied in line 15A fuse.
The ve control cable wires (listed in TABLE 3 below) routed through the driver board carry only low current (30 mA average) input signals to
control the DuoBeam™ functions and must be routed to the output of a control switch (or directly to multiple switches).
TABLE 3
Emergency Mode Flash Pattern Selection
There are seven customizable emergency ash pattern modes available based on the wire combinations shown in TABLE 4. When using
individual switches, make sure to congure all possible switch combinations.
To change a ash pattern on a single emergency level mode:
1. Power-up the unit and apply +power to the level mode wire(s) you wish to change (see TABLE 4). The unit will ash the default pattern.
2. Momentarily touch the GRN pattern select wire to (+) power to cycle through to the next ash pattern shown on TABLE 5.
3. To reset the ash pattern to the factory default, hold the GRN pattern select wire to (+) power for ~5 seconds.
