Global Tunnel Fire Detection for Roads, Railways & Cables using Linear Heat Detection with Fibre Optic Sensing Technology, plus Fire Suppression Systems.
Global Tunnel Fire Detection
Linear Heat Detection for Rail, Road & Cable Tunnels
Ideal for use in light and heavy railway infrastructure, road tunnels, cable tunnels, and cable trays, our FireLaser Linear Heat Detection (LHD) Systems from Bandweaver have a proven track record of providing fire safety and detection using Distributed Temperature Sensing (DTS) Technology, for organisations across the UK and internationally, such as Europe, Middle East, Latin America, South Pacific Asia, Africa, and India.
Rail, Road & Cable Tunnel Fire Detection & Protection
Tunnels require fire detection solutions that can withstand extreme conditions, including airflow, dust, vibration, and long distances. Key risks include vehicle fires, electrical cable faults, limited access for responders, and smoke stratification, which reduces the effectiveness of point detectors. Fires in tunnels can escalate rapidly, with temperatures rising much more quickly than in standard fires. Early intervention can contain fires to a single location, preventing extensive damage and risks to personnel.
Approved to EN54 Part 22, Heat Classification BN, our Linear Heat Detection Systems offer a highly reliable and cost-effective solution for tunnel monitoring, station platform and concourse areas. Not only do they protect the safety of passengers and staff, but they also keep your tunnel and platform areas continuously accessible, enabling trouble-free operation and minimal maintenance. Thanks to fibre-optic DTS technology, they deliver pinpoint temperature monitoring along the entire tunnel length.
Fire Detection in Harsh, Confined, High-Risk Environments
At DeXfire Limited, we support your project with comprehensive tunnel heat mapping, zone design, integration with ventilation control and emergency systems plus commissioning support for long-distance installations, ensuring compliance with NFPA 502, PIARC, and local tunnel safety standards.
Our systems increase your incident response times and improve life safety in complex underground tunnel environments. Integrating with your fire control panel, they offer three configurable smart alarm functions: static, rate-of-rise, and temperature-difference, along with smart zones for emergency exits, tunnel ends, ventilation zones, and fire suppression. The distributed measurement provides a continuous temperature profile with points every 0.5m along the sensing cable’s length, enabling early fire detection and alarms, even in wind speeds up to 10m/s.
Immune to electromagnetic interference, these systems are suitable for areas with high electromagnetic activity. With no moving parts, plus resistance to corrosion and vibrations, the sensing cable boasts a long lifespan, often exceeding 30 years.
