Fire Detection in Transport Infrastructure
Fiber optic Linear Heat Detection (LHD) is the standard for detecting fires where distances or environments challenge electrical detection systems. Designed to provide fire detection, they can also give precious insight into the condition of assets (condition monitoring) and environmental changes.
The optical fiber sensor, immune to electromagnetic interference and maintenance-free, is intrinsically safe in hazardous environments. It detects and locates temperature events and sends the data to wherever it is needed. Alarm thresholds can be set using different criteria in zones (1000 zones are available per interrogator), minimizing the risk of nuisance alarms in environments with dynamic temperature ranges.
