Intruder disturbance determination of coaxial cables by impulse reflectometer TX6000

The precise disturbance determination in fire and burglary protection systems by linear detectors, independently of its type, is a main problem of modern fire and burglary control equipment. This work presents experimental results realized on five different types of coaxial cables: RG U/6, RG 178 B/U, RG 122/U, RG 213/U and RG 214/U, every 200 m long by impulse reflectometer TX6000 in possible burglary protection systems where the coaxial cable should be used as detector. This work is just a small part of a large investigation applied for realization of PhD thesis “Fire and burglary protection using non-typical electric lines”, which was approved by University of Niš, evidence number 8/20-01-003/11-019.
