Information Cable Installation Considerations for Fire Detection
This document provides guidance on best practice for the selection and installation of cables for distributed temperature sensing (DTS) in the fire detection domain.
Information Cable Installation Considerations for Fire Detection
For tunnels, if the ceiling is flat, the cable should be installed no more than 5 meters (16.5 feet) apart, while a curved ceiling allows for up to 6 meters (20 feet) of spacing, as long as the cable is placed at
Information Setting and laying of temperature sensing optical fibers for tunnel cables
As a relatively emerging fire detection method, temperature sensing fiber optic systems can be predicted to have increasingly wide applications in the rail transit industry.
