1. Description of Flex2R/2T
TheFlex2R/2TisanexpansiondevicethatprovidesINIMcontrolpanelswithafurtherfourterminals.
T1 and T2TwoI/Oterminals,whichcanbeconfiguredas:
lZone(alsoasrollerblind/shock)
lOpenCollectoroutput
lI/Oterminal
lDoublezone
SW1 and SW2Tworelayoutputterminals,drycontactsnormallyopenwhosestatusisreplicatedbythetwoLEDs‘SW1’
and‘SW2’(theLEDsactivateintheeventofclosedcontact).
PeripheralsAs a  control panel peripheral, Flex2R/2T  requires connection via  I- BUS as well  as an address. Sub-
sequently,theoperatingmodemustbeselectedviathePrime/STUDIOsoftware,whichalsoallowsthepro-
grammingofterminals.

1.3 Operating mode
Flex2R/2Tcanoperateinseveralmodes,tobeselectedduringtheprogrammingphase.Theseoperating
modescanbedividedintothreecategories:
1. Generichome-automationmodule
2. Roller-shuttermodule
3. Lightcontrolmodule
Generic home-automation moduleDefaultoperatingmodewhenFlex2R/2Tisacontrolpanelperipheral.
Inthisoperatingmodeall4terminalsareindependentofeachotherandaremanagedcompletelybythe
controlpanel.
Roller-shutter moduleTheterminalsinusearelinkedtoaspecificfunctionwhichisdefineddependingonthetypeofhome-auto-
mationselected:
lStandard roller-shutters module
Longpressingthebutton(i.e.pressingandholdingthebutton)connectedtoterminal‘T1’(/‘T2’)will

forthedown(/up)time,summedtotheadditionalprogrammedtime,regardlessofitsstartposition.
Therollershutterwillstopwhenthebuttonisreleased.
l‘Smart’ roller-shutters module
Inthismodetherollershutterwillbehaveasfollows:
lShortpressingthebutton(i.e.pressingandreleasingthebuttonwithin1second)connected

Shortpressingthebutton(i.e.pressingandreleasingthebuttonwithin1second)connectedtoter-
minal"T1"willactivatetherollershutterinarepetitivewayinaccordancewiththefollowingscheme:
lactivemovingdownward
lstopped
lactivemovingupward
lstopped
Iftherollershutterisnotstoppeddistinctly,itwillbeactiveuntilitreachestheendofitsrun,orforthe
down(/up)time,summedtotheadditionalprogrammedtime.
lRoller-shutters module with one long press button
Longpressingthebutton(i.e.pressingandholdingthebutton)connectedtoterminal‘T1’willacti-
vatetherollershutter.Onreleaseofthebutton,therollershutterwillstop.
Theorderinwhichtheactivationsoccurisrepetitiveandinaccordancewiththefollowingscheme:
lactivemovingdownward/stopped
lactivemovingupward/stopped
Ifthebuttonispressedandheld,therollershutterwillbeactivateduntiltheendofitsrun,orforthe

lRoller-shutters module with no buttons
Inthisoperatingmodetherearenomanualoperations:therollershutterwillonlycarryoutcom-
mandsgivenbythesystem.
lVenetian blind module
Inthisoperatingmode,theVenetianblindwillbehaveasfollows:
lShortpressingthebutton(i.e.pressingandreleasingthebuttonwithin1second)connected
to‘T1’(/‘T2’),willrotatetheVenetianblindslatstotheclosed(/open)position,regardlessof
theirinitialposition,fortheprogrammeddurationofastepanduptoamaximumnumberof
programmedsteps.
lLongpressingthebutton(i.e.pressingandholdingthebuttonforatleast1second)con-
nectedto‘T1’(/‘T2’),theVenetianblindwillmovedownwards(/upwards)towardstheendof

lIfeitherofthebuttons,connectedto‘T1’or‘T2’ispressedwhiletheblindisopeningorclo-
sing,theongoingoperationwillstop.
NoteIn the case of roller shutters or Venetian blinds, the device is equipped with a function for self-calibration of posi-
tion which, if necessary, can cause the roller shutter to open completely before reaching the selected position.
If the roller shutter has been activated by control panel commands, this command cannot be canceled or stopped
by local commands (e.g. by button).

2. Installation of Flex2R/2T
Flex2R/2Tdoesnothaveintegratedtamperprotectionandexposesthecablesinusetopossibletampering.
Itisthereforeadvisabletoprotecttheconnectionsandalsothedevicebyinstallingitinsideanenclosure,
whichcanbe:
lcontrolpanelcabinet,usingtheappropriateholesonthebackplate
ljunctionbox
lelectricalcabinet
lroller-shutterenclosure
NoteIn order to comply with standard 50131, the enclosure utilized as well as the device itself must be equipped with
tamper protection.
1. Chooseasuitablemountingplacement.
Ifthecontrolpanelcabinetisused,thecontrolpanelmustbedisconnectedcompletelyfromboththe
primary-powersource(230V~)andthebufferbattery.
2. Securethedeviceenclosureinsidethebox.
Ifthecontrolpanelcabinetisused,securetheplasticenclosureviathethreadedholesontheback
plate.
3. Pullthewiresthroughthecableentryandwireupthedevice.
4. Installthedevicetamperprotection.
5. Enrollthedevice.
6. Closethebox.
7. Ifthecontrolpanelcabinetisused,powerupthecontrolpanelagainbyconnectingtheprimary-
powersource(230V~)andthebufferbattery.


Theperipheralswithvisibleterminalsandwhichdonothaveananti-tamperdevicecanstillbeequipped
withprotectionbyinterveningontheassemblyprocedure.
Pleasenotethatinordertocomplywithsecuritystandards,allthecontrolpanelperipheralsmustbepro-
tectedagainsttamper.
Hereweprovideinformationononeofthepossibleproceduresthat canbeadopted.This involvesthe
assemblyofamicroswitchonthedevice,whichsignalsanyattemptedtamper,andtheconsequentpro-
grammingoftheterminalusedforthiscontact.
1. Procureamicroswitchwithatleasttwonormally-opencontacts[A](preferablywith3contacts:COM-
NO-NC).
2. Employaterminalandprogramitasa‘24H’input,whosedescriptiontypeis‘Tamper’,balancedwith
asingle6K8Ω[B]resistance,unlimitedalarmcyclesandbelongingtoapartitionthatisviewableon
atleastonekeypad.
3. Using2wires,connectthemicroswitchtothe‘24H’inputterminal.
4. Onthemicroswitch:
lidentifythecommoncontact(COM)andconnectitusingoneofthetwowires,totheGNDter-
minalofthe‘24H’terminal[C].
lidentifythenormallyopencontact(N.O.,whichisthecontactthatgeneratesashort-circuitbet-
weenthecontactitselfandtheCOMcontactwhentheswitchleveriscompressed)andcon-
nectoneendofthe6k8Ωresistortoit[D].
Connecttheotherendoftheresistancetothewirewhichisconnectedtothe‘24H’inputter-
minal.
5. Installthemicroswitchinsuchawaythatundernormalconditionstheswitchleveriscompressed.
Ifatamperattemptoccurs,theleverwillreleasethusgeneratingtheopeningofthecontactandan
immediatealarmonthe‘24H’terminal.

2. Installation of Flex2R/2T
NoteThis wiring method can be applied in most situations, however, it is only a point of reference. In order to ensure
proper protection, you must always take in to account the specific mechanical and electrical conditions of the
device you are working on.
2.2 Connecting the Flex2R/2T module
Asaperipheral,Flex2R/2Tmustbeconnectedtothecontrolpanelthroughtheavailable‘+ D S -’terminals.
Terminals‘SW1’and‘SW2’canbeusedforconnectionswithbothACandDCpowereddevices.
Attention!Dangerous outputs
Innormaloperatingconditionsofa‘SELV’circuit,thevoltagebetweenanytwoofitsconductorsorbetween
anyofthemandGroundmustnotexceed42.4Vpeakor60VDC.Whenthesevaluesareexceeded,thevol-
tageistobeconsideredhazardous.
Theinstallercanchoosetousethe‘SW1’and‘SW2’outputstodriveexclusively2hazardousvoltagedevi-
cesor2safevoltagedevices(SELV).Themixeduseofdangerousvoltageandsafevoltageontheseter-
minalsisstrictlyprohibited.
Iftheoutputsareusedonmains(hazardous)voltage,inadditiontotheaboverequirements,itisnecessary
totakethefollowingcompulsorymeasures:
ltoconnectinseriesanappropriateprotectionfusetotheselectedoutput
ltousethroughphaseonlyorthroughneutralonlyforalltheterminals

Theconnectionsforhome-automationfunctions,orforoperatingasaroller-shutterorlightcontrolmodule,
dependontheoperatingmodeselectedduringtheprogrammingphase.
lHome-automation module
The4terminalsareallindependentandcanbecontrolledviathecontrolpanel.
Theycanbewiredforanyofthefunctionsavailabletothem.
