Long-Range Monitoring
A single channel can cover extended routes such as tunnels, utility corridors and industrial sites.
Distributed Fiber Optic Sensing
Distributed Fiber Optic Linear Heat Detector
Passive sensing fiber provides real-time temperature monitoring, alarm positioning and platform linkage across long, continuous routes.
Product Profile
10 kmMaximum distance per channel
Product Overview
Capabilities and functional features
Designed with reference to GB 16280-2014, the system combines long measuring distance, continuous monitoring, passive sensing and electromagnetic immunity.
Resettable Detection
The sensing element can continue monitoring after the abnormal temperature condition clears.
Rate-of-Rise and Fixed Temperature
Combines temperature change and threshold logic to identify anomalies.
Passive and Interference Resistant
The sensing fiber needs no field power and resists electromagnetic interference.
Applications
Where It Fits
Suitable for long, complex spaces with positioning requirements or environments where powered field sensors are undesirable.
Utility Tunnels
Continuous monitoring and zone management across long enclosed corridors.
Road and Rail Tunnels
Covers extended routes and helps position abnormal temperature sections.
Oil Tanks and Storage
Supports passive sensing around critical areas such as floating-roof tanks.
Cable and Conveyor Routes
For long cable facilities, conveyor systems and industrial routes.
