Fiber Optic Cable Fire Detection

Schlumberger dual integrity systems use fiber optic technology to combine speed of detection dependability and versatility into proven fire detection solutions.

Fiber optic cable fire detection.

Optical fiber cables are manufactured with excess fiber length in buffer tubes to avoid change. The fire detection system is worth its weight in gold. 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. Fibre optic linear heat detection.

This document describes the guideline for locating the fault in optical fiber cable after installation or during maintenance of the cable. The cable can be connected in a loop or alternatively as a one or two channel single ended system. Leverage fiber optic systems for the power industry including augmenting temperature data with added functional packages to increase data value. 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.

Up to 4 km of sensor cable may be installed in the area to be protected. 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. Detection systems are ideal for use in railway tunnels which are often in remote locations that require reliable robust surveillance systems. Fire detection monitoring dual integrity fiber optic solutions.

The sensor cable is certified fibre optic cable installed in a similar manner to electrical based linear heat detection technology. 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. Ap sensing is proud of our global contributions for pipeline leak detection high voltage power cable monitoring and fire detection. Neal retzer ejmt resident engineer pe 2 and jason bonger ltc ops 1 at the colorado department of transportation explain why cdot invested in the lios de tect fiber optic fire detection system.

Optical fiber cable fault location detection procedure issued august 2013. 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. Lios de tect is developed for efficient and pinpoint fire detection in road and rail tunnels.
