DTS uses optical fiber as a continuous temperature sensor. Selected fire-suitable configurations up to 10 km and the fourth-generation 12 km configuration can apply the same sensing and installation principles to Fiber Optic Linear Heat Detection (LHD); alarm zones, thresholds, response, fault monitoring and fire-system interfaces must meet applicable fire-alarm requirements. Existing 20/30 km long-range and oil/geothermal versions are not intended for this fire application.
For advice on cable tray fire detection system, share your monitoring distance, installation environment and integration requirements with our engineering team. We can help assess sensor placement, commissioning and acceptance criteria for your project.
