Important Product Safety Notice

Product Identification

This is a Product Safety Notice. Vilter has determined that certain software program versions on Vilter flash cards (part number 3485FCSD) in Vission 20/20 panels shipped between September 24, 2019, and January 3, 2021, could cause the Vilter compressor to operate beyond preassigned operational limits and fail to activate safety shutdowns.

This circumstance arises when the Vission 20/20 panel is connected to an outside third-party monitoring system, and that system sends a simultaneous start/stop command to the compressor. This could result in the compressor operating fully unloaded with certain fault conditions not monitored as intended, leading to an overheated and seized compressor. To date, Vilter is aware of two incidents where this situation occurred.

Affected Vilter products can be identified by checking the software program version located on the front screen of the Vilter Vission 20/20 Panel.

Required Action

If your flash card is using one of the affected software versions, the Vilter Vission 20/20 Panel software must be immediately updated with a new flash card. This software update should occur whether or not your system is connected to an outside third-party monitoring system.

Guidance for Distributors and Contractors

Vilter Distributors and Contractors should take immediate steps to determine if they have sold or installed any Vilter Vission 20/20 Panels or Flash Cards using the impacted software program versions, or if any are still in their possession.

If such Vilter Vission 20/20 Panels or Flash Cards have been sold, immediate measures must be taken to contact the customer and advise them of the issue by sending them this notice so they can receive the software update. If direct customer contact is not preferred, please provide Vilter with the names and contact information for all impacted customers, and Vilter will contact them.
