Abstract
IMPROVEMENT THAT ALLOWS TO LOCATE FAULTS IN ALARM SYSTEM MONITORING LINES. CONSISTENT IN A LINE (N) THAT IS ACCESSIBLE FROM THE MONITORING CENTER; IMPEDANCES (B1, B2, B3) THAT CONNECT BETWEEN DIFFERENT POINTS OF THE SURVEILLANCE LINE (A1, A2, A3) AND THE LINE (N); AND DIODES (C1, C2, C3) IN SERIES WITH THE IMPEDANCES (B1, B2, B3) SO THAT THESE DO NOT DISTURB THE MEASURES MADE IN THE SURVEILLANCE LINE (A1, A2, A3), BETWEEN POINTS A AND M OF THE LINE OF SURVEILLANCE. IF A CUT (F, O D, O E) OCCURS ON THE LINE (A1, A2, A3) MEASURING THE IMPEDANCE (B1 OR B2 OR B3) BETWEEN POINT A AND POINT N WE WILL KNOW AT WHAT HEIGHT THE CUT IS.
