Increasing tunnel safety with high performance resettable line-type heat detection DTSX1

Kidde APF Article,
January 2025

Kidde Australia now offers fiber-optic line-type heat detection technology that is based on the scattering of light within a fiber-optic cable. This technology provides several advantages, including:

  • Rapid and accurate location of incidents
  • Enhanced reconfigurability on-site
  • Seamless integration with SCADA and control systems
  • Early detection of heat
  • High accuracy that reduces false alarms
  • Flexibility for various applications
  • Individual zone monitoring

These features make it a reliable solution for effective heat detection.

Fiber-optic heat detection offers a wide range of advantages:

  • Temperature profiles with time stamp
  • Cost savings over long distances
  • Maintenance-free, robust sensor cables that ensure low lifetime ownership costs
  • Easy installation and integration with fire management systems
  • Capability to function as a standalone system if needed
  • No risk of sparks
  • Operates effectively in harsh environments, such as wash-down areas and high humidity conditions

Yokogawa’s DTSX system can measure temperature in sections every one metre, covering distances of up to 16 kilometres per channel. It employs backscattering and reflectometry technology based on the Raman effect, where changes in the light source due to thermal influences indicate temperature variations.
