Fibre Optic Linear Heat Detection System (LHDS) Overview
Spectron Group's Fibre Optic Linear Heat Detection System (LHDS) is an advanced fire detection technology built for mission-critical environments such as tunnels, metros, cable trays, industrial plants, and offshore platforms. Utilizing VIAVI's Raman-scattering-based Distributed Temperature Sensing (DTS), this system enables continuous real-time temperature monitoring along the entire length of a heat-sensitive fiber-optic cable. It allows for early fire detection, even before smoke appears, and pinpoints the exact fire location for rapid emergency response. Spectron's LHDS is ideal for large-scale and harsh environments where traditional point-based detectors fail.

Key Metrics
Spectron Group's Fibre Optic Linear Heat Detection System delivers unmatched fire safety through real-time, continuous temperature monitoring across long distances using fiber-optic technology. By leveraging distributed temperature sensing (DTS) based on Raman scattering, the system provides early detection of heat build-up before smoke or flames appear. This capability ensures immediate response, reduces damage, and safeguards critical infrastructure. With pinpoint accuracy in fire location detection, Spectron's LHDS drastically shortens emergency response time. It operates flawlessly in high-risk environments like tunnels, metros, oil & gas facilities, industrial zones, and offshore platforms—where traditional fire detection systems often fail due to dust, humidity, and fluctuating temperatures. The system is scalable, low-maintenance, and easily integrates with SCADA, fire alarm control panels, and building management systems for centralized, automated fire response.
Continuous 24/7 monitoring across cable length
Early fire detection before visible smoke
Pinpoint fire location accuracy
Resistant to moisture, dust, temperature changes
Seamless third-party system integration
Low maintenance with high durability
Process / Working
The Fibre Optic Linear Heat Detection System (LHDS) works by deploying a distributed fiber optic sensor cable throughout a facility or infrastructure. Using DTS technology based on Raman scattering, it continuously monitors for temperature fluctuations. When abnormal heat is detected, the system triggers an automatic alarm and pinpoints the fire's exact location. This enables a rapid, focused emergency response and minimizes damage. The system operates reliably in environments like tunnels, metros, power plants, oil & gas sites, cable trays, and even offshore rigs.
Spectron's LHDS integrates smoothly with fire suppression systems, SCADA, FACP, emergency ventilation, and Building Management Systems (BMS), creating a centralized and intelligent fire safety architecture.
