Title: Flashcard Corruption Exhibiting Unrecoverable Blue Screen Condition

Scope:

Vission 20/20 programs – version 4494 through 4550.

Overview:

Changes to the flashcard structure will prevent flashcard card corruption. This change will target program versions in the ranges of 4494 through 4550.

To identify the program currently installed in the 20/20 panel;

  1. Press the Help button.
  2. Press the Version button.
  3. Inspect “Software Version:” number.

For programs within the specified range, if corrective action is not taken, the flashcard corruption problem will cause the Vission 20/20 panel to exhibit an unrecoverable blue screen condition. If your 20/20 panel exhibits an unrecoverable blue screen, a new flashcard will be required for your panel. Please contact the Vilter Service and Warranty department to help facilitate this.

If your panel does not exhibit the blue screen condition, but your Vission 20/20 program falls within the above version range, a new program needs to be installed on the existing flashcard to prevent the unrecoverable blue screen condition from occurring.

The new program can easily be copied onto the existing 20/20 flashcard using a Windows based computer and a flashcard reader.

Procedure to correct flashcard corruption problem leading to blue screen condition;

  1. Open web browser and navigate to
  2. Right-click on “vcontrol.img” and select “Save Target As…” option, and save this file to your Desktop or desired directory. It is a 91MB file, so it may take a few minutes to download.

  1. For precautionary measures and archiving purposes, backup the database of the Vission 20/20 panel onto a thumb drive. If you are unsure of how to do this, reference the “Database Backup Procedure.doc” located at

After the new vcontrol.img file has been copied to the flashcard, a data migration procedure needs to be done to restore all setpoints to the new program database.
