Fiber Optic Cable Fire Detection

Fibre optic linear heat detection.

Fiber optic cable fire detection.

Best described as a continuous linear thermometer that actively reports temperature readings fiber optic linear heat detection is immune to emi and rfi and can be configured to offer programmable alarm criteria along the length of the cable. Optical fiber cables are manufactured with excess fiber length in buffer tubes to avoid change. Lios de tect is developed for efficient and pinpoint fire detection in road and rail tunnels. The cable can be connected in a loop or alternatively as a one or two channel single ended system.

With the optasense pipeline leak detection system the fiber optic cable acts a fully distributed sensor that offers thousands of detection points along the entire pipeline capable of pinpointing the location of a leak within 10m in real time. Fire detection monitoring dual integrity fiber optic solutions. Fiber optic lhd solution advantages a single passive cable easy to install immune to emc dirt dust and humidity maintenance free longest life time largest coverage functional even at 1000 c precise location of all fi re events fire size and spread monitoring five different alarm criteria for quick detection flexible zone and alarm confi. The fire detection system is worth its weight in gold.

Up to 4 km of sensor cable may be installed in the area to be protected. Optical fiber cable fault location detection procedure issued august 2013. The benefits of the fire detection system according to cdot. Fiber optic cables represent the future of linear heat detection and it s available now.

Schlumberger dual integrity systems use fiber optic technology to combine speed of detection dependability and versatility into proven fire detection solutions. The sensor cable is certified fibre optic cable installed in a similar manner to electrical based linear heat detection technology. Ap sensing is proud of our global contributions for pipeline leak detection high voltage power cable monitoring and fire detection. This document describes the guideline for locating the fault in optical fiber cable after installation or during maintenance of the cable.

Since its initial introduction in 1997 it has revolutionised the safety standard in underground transport facilities as it enabled the complete monitoring of the entire tunnel length for the first time. The fiber optic sensing association fosa today released details on more than 1 300 installations of distributed fiber optic sensing dfos around the world the largest representative sample ever published. Detection systems are ideal for use in railway tunnels which are often in remote locations that require reliable robust surveillance systems.
