Urban metro systems demand fast, reliable fire detection to protect passengers and infrastructure and ensure continuous operation. For the Tianjin Metro in China, a scalable solution was required to deliver accurate, real-time monitoring across an expanding network of tunnels.
Bandweaver deployed its FireLaser fiber optic Linear Heat Detection system, providing continuous temperature monitoring along the tunnel infrastructure. Using distributed sensing, the system delivers full coverage with metre-level resolution, enabling early detection and precise localisation of potential fire events.
Designed with smart zoning and advanced alarm capabilities, including rate-of-rise and deviation detection, the system allows operators to respond quickly while maintaining high confidence in alarm accuracy.
The solution integrates with fire alarm and control systems, supporting a distributed architecture where each station can operate independently while maintaining network-wide visibility.
The result is a reliable, low-maintenance fire detection solution that enhances safety, reduces risk, and supports the efficient operation of critical metro infrastructure.
