What exactly are we testing?

Your VdS-approved detectors have proven in extensive practical tests in the worldwide unique testing infrastructure of our Cologne laboratories that they reliably do the decisive work: Saving lives in the event of fire.

The functional safety is clearly proven

  • in real test fires (detection of open fires and smouldering fires),
  • in the unique sound measurement room,
  • in the mechanical smoke generator,
  • after artificial ageing,
  • after shock and special impact and vibration tests,
  • with temperature fluctuations,
  • under difficult environmental conditions such as rust, electromagnetic influences etc.


Always included (and clearly exceeded): German and EU fire protection standards.

VdS-approved detectors also score best with Stiftung Warentest and ZDF. And the WIK/ASW Enquete, the most comprehensive industry survey in Germany, Austria and Switzerland, proved for many years in a row (study 2016 with buying up WIK magazine unfortunately discontinued): the VdS quality seal is the most important purchasing criterion for fire protection experts.
