Wiring the Valor in the Vehicle
Takedown Lights
When 12 Vdc (+BAT) is applied to the Takedown control wire (white/black), the
takedown LEDs turn on. Takedown overrides Flash Takedown/Alley and Front Cutoff.
Scene Light, Left and Scene Light, Right
This function applies only to light bars with Spectralux Technology (Valor and Vision
SLR). To use this function with the Serial Interface Module, place SW2 Switch 3 in the
Module in the down position (ON). When 12 Vdc is applied to the Scene Light, Left
control wire (blue/black), the left half of the light bar lights up. When 12 Vdc is applied
to the Scene Light, Right wire (black/white/red), the right half of the light bar lights up.
Intersection and Light Bar Test are unavailable with these options.
Low Power
NOTE:
Low power mode is disabled when the light bar is in MODE 3 or displaying the
Intersection flash pattern.
USE THE DIMMING/LOW POWER FUNCTION PROPERLY: Enabling the
Low Power function in the light bar may cause the light output to fall below
certain light output standards and guidelines for emergency warning lights.
Use extreme caution when using this function. Ensure that the ambient light
conditions are low enough that you are seen and that the reduction of glare
from the light bar is safer than full light output in the situation. Failure to heed
this warning may result in serious injury or death to you or others in your
vicinity.
When 12 Vdc (+BAT) is applied to the Low Power control wire, the LEDs are dimmed
to approximately 50 percent of their full brightness. Low Power is only functional in
MODE 1 or MODE 2. Low Power is disabled when switching to another flash pattern,
including Intersection. (SW2 Switch 3 in the Serial Interface Module must be in the up
position for this function.) To use Low Power again, disconnect 12 Vdc from the Low
Power control wire and reapply 12 Vdc to the Low Power control wire after a change
in flash pattern occurs.
Ignition
Connect the white wire from the supplied J1 cable harness on the Interface Module
to a 1 A fuse. Connect the fuse end as close as possible to switched ignition power.
Power should also be present in the cranking position.
Connect the black and black/white wire from the 24-pin cable harness on J1 from the
Serial Interface Module to battery ground (–GND). Use 16 AWG wire to extend the
cable length.
