Auxiliary Input
Ifconnectedatthetimeofinstallation,applicationofapositive(+)12-24VdcorgroundtotheAUXIN
connectionproducestheWARNpatterndescribedabovein“WARNButton.”Whenthepositive(+)
12-24VdcorgroundisremovedfromtheAUXINconnection,theWARNpatternstops.Slideswitch
activationalsooverridestheWARNpattern,turningitoffanddisplayingtheselecteddirectionalpattern.
WhentheslideswitchisreturnedtotheOFFposition,thewarningpatternreturns,providedthereisan
activesignalattheauxiliaryinput.Typically,theoperatorhasnodirectcontrolovertheauxiliaryinput,
because it would be tied to another separate device for its power signal.
Turn Signal Override
Whenthecontrollerisinstalledwiththeturnsignaloverridefeatureconnectedtothevehicleturn-signal
circuit,thecontrollerstopsanyactivepatternandashestheappropriateendlampsinsequencewiththe
turnsignalsorhazardlights.Nooperatorinputisneededtoactivatethisfeature,ifconnected.
Testing the Installation
LIGHT HAZARD—To be an effective warning device, an emergency warning
system produces bright light that can be hazardous to your eyesight when
viewed at a close range. Do not stare directly into the lights at a close range or
permanent damage to your eyesight may occur.
Aftertestingtheinstallation,testtheemergencywarningsystemtoensurethatitisoperatingproperly.Also
test all vehicle functions, including horn operation, vehicle safety functions, and vehicle lighting systems to
ensureproperoperation.Ensurethattheinstallationhasnotaffectedthevehicleoperationorchangedany
vehicle safety functions or circuits.
Donottestthelightsystemofthevehiclewhiledriving.Operatingthevehiclewarningsystemsmayposea
hazardtotheoperatorandotherdriversifthesystemsdonotfunctionasexpected.Testthevehicleonlyin
acontrolledenvironment.Aftertestingiscomplete,provideacopyoftheseinstructionstotheinstructional
staff and all operating personnel.
