Cause

Alarm engine does not provide functionality natively to display personnel name on invalid attempt at a door, Plain English program must be used.

Resolution

The basic idea is to set the door’s description to the value of the door’s LastInvalidEntry (or LastInvalidExit) attribute, and use the wild cards %N and %D to embed the Door’s name and LastInvalidEntry (or LastInvalidExit) into the alarm’s feedback messages.

Since the controller is unable to resolve the path to the personnel object pointed to by lastInvalidEntry/LastInvalidExit a CyberStation program is needed.

Also, because the InvalidAttempt flag of the door only persists for one scan it is necessary to latch its value into a numeric point.

In the controller write a looping program to latch the value of the door’s InvalidAttempt flag.

CONTROLLER PROGRAM

1:

  If Vault_Door InvalidAttempt then

    VaultDoorInvalid = 1         <---VaultDoorInvalid is a numeric point in the controller

    Goto 2

  Endif

 2:

  If VaultDoorInvalid = 0 then Goto 1

CYBERSTATION PROGRAM

 Write a program in CyberStation to monitor VaultDoorInvalid and set the door’s description to LastInvalidEntry

  WaitForInvalid:

  If LocalNetwork\ACX2.13\VaultDoorInvalid then

    Print LocalNetwork\ACX2.13\Vault_Door LastInvalidEntry to STR1

    Goto SetDrDescription

  Endif

 SetDrDescription:

  LocalNetwork\ACX2.13\Vault_Door Description = STR1  <--- STR1 is a String object in CyberStation

  Goto ResetFlag

 ResetFlag:

    LocalNetwork\ACX2.13\VaultDoorInvalid = 0

   If LocalNetwork\ACX2.13\VaultDoorInvalid = 0 then Goto WaitForInvalid

 ALARM ENROLLMENT

 Lastly, create an expression AlarmEnrollment , set it to

            Description <> “”

And attach it to the door.

 When an invalid attempt is detected the alarm stays ON until the door object is edited (from the alarm view itself) and the description cleared.
