IMPORTANT

AnMOVorreversebiasdiodemustbefitteddirectlyacrossallDClock
terminalstopreventbacke.m.f.fromthelockcoilcausingmalfunction
andpossiblelongtermdamagetothedoorpanelorcontroller.


EXLK CONNECTION

A“presstoexit”(PTE)buttonisusedtooverridethelockandallowegressfromthebuilding.ThePTEbuttonshouldbe
momentaryactionwithbothN/OandN/Ccontacts.TheN/Ocontactsareconnectedacross0V&EXLKinthedoorpanelto
provideafixed10secondtimedlockrelease.WithconstantlyenergisedlocksitisrecommendedthattheN/Ccontactsare
alsoconnectedinserieswiththelocksupplytoprovidefailsafeoperationofthelock.

T/G CONNECTION

AN/Cdoorcontactcanbeconnectedacross0V&T/Ginthedoorpaneltodetectwhenthe entrancedoorisopened.
Whenthecontactsopenthelocktimeiscurtailedtoreducethelikelihoodofothervisitorsenteringduringthesamelock
releaseperiod(ie.tailgating).Thetelephone“dooropen”LED’swillilluminategreenwhenthedoorisopenifenabledin
the“DoorEntrySetup”programming.IfadoorcontactisnotfittedthentheT/Gterminalmustbelinkedto0V.
