3.3KeycardSequence



Eachtypeofkeycardcanbeassignedasequencerangethatindicatesthenumberoftimesanewkeycardcanbe

made,butnotusedinthelock,beforethelockwillbeunabletorecognizethenextlockcodeandpermitentryinto

theroom.Thissequencerangecanbesetfrom1‐15skips.



Whenanewkeycardismadeitisencodedwiththefollowinginformation:



1. KeyRecordNumber–Anumberthatindicateshowthecomputerhasfiledtheroomnumber.



2. KeyCombination–Arandomcodenumbergeneratedbythecomputerwhenthekeyismade.



3. IdentificationNumber(ID#)–Anumberfrom1‐255thatisassignedbythecomputertodifferentiateone

masterkeycardfromanother.



4. NewKeyDate/Hour–Thedateandtimethatthekeycardwillbeginworkingonthelock.



5. ExpirationDate/Hour–Thedateandtimethatthekeycardwillceasetoworkinthelock.



6. SequenceNumber–Thenextsequencenumberassignedbythecomputer.



7. PropertyNumber–Thenumberassignedtotheproperty.



Whenakeycardisinsertedintothelockandremoved:



1. ThelockfirstconfirmsthattheKeyRecordNumberandPropertyNumberstoredinitsmemorymatchesand

numbersonthecard.



2. ItthencheckstoensurethattheNewKeyDate/Timeonthekeycardisequalto,orlaterthatthekeydateand

timestoredinitsmemory.



3. Finally,itcheckstheSequenceNumberonthecardtoensurethatitisequaltoorgreaterthanthesequence

numberinitsmemory,butdoesnotexceedtheprogrammedSequenceRange.



Whenthesethreechecksareconfirmed,thelockupdatestheinformationstoredinitsmemory.Itthenperforms

thenormalchecksandreleasesthelockingmechanism.
