The new DPT version 15.1.12736 is available for download in the protected area of our website. This includes the firmware release V3.5.4 for the DC3500 control panels.

Included functions

  • Simplified version change in the DPT – when upgrading/downgrading the DC3500 firmware, you can now switch directly to the next main version up (e.g. from V3.3.0 to V3.4.0); individual steps via intermediate releases are no longer necessary
  • Manual start of the query time at FBA Switzerland


  • Memory optimisation of the central computer (CRC notification)
  • Change of the upgrade/downgrade function for the firmware of the fire brigade module FBM from the control panel version 3.5.0
  • Adaptation of the GLT interface to prevent communication issues when restarting external clients (e.g. building management systems)
