Description
Ultrasonic
Activated
TheOAC-UCeilingMountLineVoltageOccupancySensorisanUltrasonic(US)motionsensinglightingcontrol,
usedforenergysavingsandconvenience.Thesensorproducesalowintensity,inaudiblesoundtodetectoccupancy
inaroom.Changesinthesensor’sacousticwavecausedbymotion,suchaswalkingintheroom,reachingfora
telephoneorswivelinginachair,willcausethelightstoturnON.Thesensordoesnotrespondtoaudiblesound.
Thesensorincludesself-adaptivetechnologythatcontinuallyadjuststoconditionsbyadjustingsensitivityand
timedelayinreal-time.
Location
Themaximumcoverageareamayvarysomewhataccordingtoroomshapeandthepresenceofobstacles.Decrease
totalcoverageareaby15%for“soft”rooms(forexample,heavydraperiesorheavycarpeting).Thesensormusthavea
clearviewoftheareatobecontrolled.Thesensorwillnot“see”throughglass.Mountingheightshouldnotexceed12
feet.Optimummountingheightis8to10feet.Mountthesensorsothegrillesfacetheopenportionoftheroomand
arenotfacinganearbywall,door,windoworotherobstructingobject.Avoidpointingintohallways.Mountingatxture
heightismosteffective.*Topreventfalseactivation,thesensorshouldbemountedawayfromtheairsupplyducta
minimumof4to6feet.
Installation
TheOAC-Usensorcanbemountedtoastandard2.125"deepx4"octagonor2.125"deepx4"foursquareelectrical
box(foursquareboxrequiresatwo-gangmudring).
Wiring
CAUTION: Before installing or performing any service on a Greengate system, the power MUST be
turned OFF at the branch circuit breaker. According to NEC 240-83(d), if the branch circuit breaker
is used as the main switch for a fluorescent lighting circuit, the circuit breaker should be marked
“SWD”. All installations should be in compliance with the National Electric Code and all state and
local codes.
NOTE REGARDING COMPACT FLUORESCENT LAMPS: The life of some compact fluorescent lamps (CFLs) is
shortened by frequent automatic or manual switching. Check with CFL and ballast manufacturer to determine the
effects of cycling.
1. MakesurepoweristurnedOFFatthebranchcircuitbreaker.
2.Wireunitsasshowninwiringdiagramsperapplicablevoltagerequirements.(Usetwist-onwireconnectorsfor
allconnections)CAPALLUNUSEDWIRELEADS.
3.Mountunittoceiling,junctionboxorroundxturewithraceway.
4.TurnpowerbackONatthebranchcircuitbreakerandwait2minutesfortheunittostabilize.
5.Makenecessaryadjustments.(SeeCheckoutandAdjustmentssection)

Ifthisfeatureisnotneeded,leavethelightlevelatmaximum(fullyclockwise).
TheDaylightingfeaturepreventsthelightsfromturningONwhentheroomisadequatelyilluminatedbynaturallight.If
thereisenoughlightintheroomregardlessofoccupancy,thesensorwillholdthelightsOF F.Ifthereisnotenoughlight
intheroom,thesensorwillallowthelightstoturnONwhenoccupied.HoweverthelightswillnotturnOFFifthelight

Note:Setthelightlevelwhentheambientlightisatthelevelwherenoarticiallightisneeded.
1. WiththeloadON,putthesensorintoTestMode.ToplaceintoTestMode,toggleDIPSwitch10outofitscurrent

3.Setthelightleveltominimum(fullyCCW).
4.Leavetheroomandletthesensortime-outsolightsareO F F.EnterthespaceandlightsshouldremainOFF.
5.MakesurenottoblockthesensorfromthedaylightsourceandadjustthelightlevelpotentiometerCWinsmall
incrementsuntilthelightsareON.(Pause5secondsbetweeneachadjustment)
6.OncethelightsareON,theloadconnectedtothesensorwillnotturnONiflightlevelsareabovethe

Time Delay Adjustments
Peoplewhoremainverystillforlongperiodsoftimemayneedalongertimedelaythanthedefaultsettingof10

byalternatelymakingslightadjustmentstoeithertimedelay(by2minuteincrements)orsensitivity,sothereshouldbe
noneedformanualadjustment.Ifmanualadjustmentisdesired,refertoTimeDelaysettingsinDIPSwitchlegend.
