Install Sentry Control Box
Thecontrolboxshouldbeinstalledinalocationthatwillnotrequire
theeightfootlinearactuatorcabletobespliced.Ifthecablemustbe
spliced,refertothesplicinginstructionsbelow.Themostcommon
locationwouldbeonafenceorwalladjacenttoyourgate.Avoid
placingthecontrolboxbehindsolidmetalobjectsthatmightinterfere
withthereceiverreception.Theantennaforthereceiverislocated
insidethecontrolboxandthiscouldreducetheoperatingrange.
1. Usecontrolboxasatemplatetodetermineandmarkthe
mountingscrewlocationsusingthe4mountingholesshownin
gurehere.
2. DrillmountingholesforscrewsDONOTATTEMPTTO
HOLDTHECONTROLBOXINPLACEWHILEYOU
DRILLTHEMOUNTINGHOLES.Thiscoulddamage
thepreinstalledcomponents.
3. Attachthe4#12hexheadselftappingmetalscrews.

TheSentrylinearactuatorcomeswith8feetofcable.Avoidsplicing
thiscableifpossible.Ifthecontrolboxmustbelocatedinsucha
waythatsplicingisrequiredfollowtheguidelinesbelowtoavoid
problems.Determinethelengthofadditionallinearactuatorcable
neededandeitherbuildityourselforvisitwww.sentrygateopener.
comfororderingthelengthofextensioncableneeded.
1. Locatethelinearactuator8pinconnector.Measure18”from
connectorandmark.
2. Cutcableatthe18”mark.Thiswillallowenoughcabletobesplicedandplacedinthewire
compartment.
3. Bringextensioncableintocontrolboxandsplice5wiresusingwirenuts.
4. Useapprovedweathertightelectricaljunctionboxforthesplicelocatedoutsidethecontrolbox.
