Fusing - 21TR TM
The light bar should be installed with an external fuse or circuit breaker in the RED lead of the 11 conductor cable. The recommended
external fuse size for the light bar is 15A. The internal circuitry of the Central Controller is reverse polarity protected. Each output on
the Central Controller board is protected against over current and over heating with automatically resetting output devices.
wiring - 21TR TM
Connect the black lead to a solid frame ground (earth), preferably the (-) or ground (earth) side of the battery, and the power wire to
the +12V terminal of the battery. Connect the remaining wires in the 11 conductor cable as shown in Table 1.
Table 1 - Control Wire Definitions - 21TR TM
Note: All control inputs are +power enabled.

Flash Pattern Selection - 21TR TM
The Pattern Select wire is the Green wire in the 11 conductor control cable and is activated by momentarily touching the wire to +12V.
There are seven total combinations of unique flash patterns that can be defined with a unique flash pattern. It is also impor-
tant to understand whether the light bar will be controlled by a progressive style switching controller, or individual switches.
This often leads to confusion in selecting patterns and may result in the end user not achieving the desired outcome. This is
discussed in the section titled "Progressive vs. Independent Switching".
diagnostic Test
There is also a diagnostic test that can be run using the Green pattern change wire. Apply +12V to the Green wire (only). The lights
will turn on one at a time and then turn off. At the end it should flash all emergency lights at the same time three times. Note that
it can only be activated by applying power to the Green wire at start up. If the unit has been energized with any other wire, power
needs to be removed entirely from the light bar before applying power to the Green wire to enter into this mode again.
This Product contains high intensity LED devices. To prevent eye damage, DO NOT
stare into light beam at close range.
