Installation
– Avoidthefollowinginsidethemonitoring
area:
– directhotorcolddraftsandaircondi-
tioningoutlets
– heatsources(aminimumdistanceof
1.5mtoaradiatorisnecessary)
– windows
– smallanimals
– directsunlight
– Thedetectorcannotdetectthroughglass.
– Whenusingtwoormoredetectors,thebest
coverageisachievedbyoverlappingthe
monitoringareas.Thedetectorsdonotaf-
fecteachother.
Installationpreparations
1. Selectasurfacethatissolidandfreeof
vibrations.Inordertoensuretheintru-
sionsecurityofdroppedceilings,detect-
orsshouldmonitoreachother.
Mounting
Notice!Removingmaskingfromthemirrorele-
mentsleavesadhesiveresiduethatpollutesthe
mirrorandleadstomalfunctionofthedetector.
VdSrequirementsprohibitmirrormasking.
1. Toremovethecover,insertathinblade
screwdriverintothenotchatthebottomand
pryitopen.
2. Toremovethecircuitboard,pressoneof
thecircuitboardretainertabstowardsthe
sideoftheenclosureandliftthecircuit
boardoutoftheenclosurebase.
3. Slidethemirroroutofitstracks.
Notice!Toexchangethemirror,removethe
currentmirrorandslidetheothermirrorinto
thetracks.
4. Openanappropriatewiringknockoutbytap-
pingitwithascrewdriverthenroutethewir-
ingthroughtheopening.
5. Forstrainrelief,attachthecabletothe
cabletiewiththesuppliedplastictie-down.
Surfaceorcornermounting
1. Openeithertwoofthefoursurfacemount-
ingholesorthetwocornermountingholes.
2. Usetheenclosureasatemplateandmark
thelocationforthemountingscrews.
3. Firmlymountthedetectorwithappropriate
hardwaredependingonthemountingsur-
face(e.g.,anchors).
4. Insertthemirrorandcircuitboard.
Bracketmounting
Notice!Whenusingabracket,misalignmentof
thedetectormightreducethemonitoringrange.
1. Mountthebrackettothemountingsurface.
2. Knockoutthebracketmountingholeinthe
enclosurebaseandattachtheenclosureto
thebracket.
3. Insertthemirrorandcircuitboard.
Formoreinformationonthebracketmounting,
refertotheinstallationmanualofthebracket.

Caution!
Excessivehandlingofthemirrorsur-
facemayleadtodamageandmalfunc-
tionofthedetector.

Danger!
Injuriesanddamageofthedetector
duetoelectricityarepossible.Inspect
allconnectionstobecorrectbeforeap-
plyingpower.

Configuration
1. Setthesensitivitytooneofthefollowing
settingsusingthesoftware:
Standardsensitivity(default)
– Protectionagainstfalsealarms
– Tolerancetoextremeenvironmentalcondi-
tions
– Notrecommendedforcurtainmirrorversion
Highsensitivity
– Recommendedsettingforanylocation
whereanintruderisexpectedtocoveronly
asmallportionofthemonitoringareaor
whenquickcatchperformanceisdesired
– Tolerancetonormalenvironmentalcondi-
tions
– Highresponsesensitivity

Tosetupthedetector
1. Mountthecover.
2. Insertthetamperscrew,ifdesired.
3. Applypowertotheunit.
4. Waitforapproximatelytwominuteswithno
motioninthemonitoringarea,thenbegin
walktestingacrossthepatternbelow.
5. Walktestthedetectorfrombothdirections.
Theboundariesaredeterminedbyactivation
oftheLED.
6. Ifthedesiredrangeisnotachieved,angle
themirrorupordowntoassurethemonitor-
ingpatternisnotaimedtoohighortoolow.
7. Ifrequired,installthesecurityseal(P/N
3.102.389.687)betweenthebaseandcover
besidethecoverlockingscrew.

Maintenance
– Checktherangeandmonitoringareawitha
walktestatleastonceayear.
– Instructtheendusertocheckthedetector
dailybywalkingthroughtheouteredgeof
themonitoringareaandobservingtheLED
operation(ifused).Thisassuresanalarm
outputpriortoarming.
