Steady Burn Setting - 21TR Plus TM
The Steady Burn feature allows up to two (2) of the light bar's light heads to be designated to operate in Steady Burn mode. The Steady
Burn light heads are always connected to connectors P9 & P10.
The Steady Burn outputs are enabled by the 3-Level control inputs. The light bar may be configured so that Steady Burn light
heads are on when either L1, L2 or L3 are active (JP1 position); when L2 or L3 are active (JP2 position) or just when L3 is ac-
tive (JP3 position). Simply move the jumper to the appropriate location (JP1, JP2 or JP3). Refer to the detail in Figure 6 and 7.
Note: HOLd the Pattern Select wire to +POwER source until you are sure ArrowStik pattern has changed (~1 second) before
releasing the wire from the +POwER source. To restore the Factory default ArrowStik patterns, hold the PGM wire on the
+POwER source for ~four (4) seconds.
When the FLASH function is selected, the same procedure applies as above, but you will notice in Table 5 that the patterns are not
grouped by the number of heads or outputs. These are traffic warning patterns and work equally well for any configuration of light
heads. There are a total of 9 (1-9) traffic warning patterns available. Flash patterns marked with an asterisk "*" may also be select-
able in Fast, Medium or Slow flash rate. When you have programmed the desired pattern for the selected function, proceed to Step 4.
Step 4
Select another mode and repeat the previous steps until all of the functions are programmed as desired.
NOTE: Table 5 shows ArrowStik® patterns for all ArrowStik configurations. Your light bar is capable of only the patterns
appropriate for the configuration purchased.
