Abstract

Surveillance lines for alarm systems. Characterized to dispose, in parallel with such lines, an auxiliary line that is communicated with the corresponding line of surveillance, through pairs of zener diodes in series (a, b) and with polarities in opposition, being, the values of the zener tension of the diodes, staged along the installation, being such growing values from one end to another of the installation; because if a court is produced in such line, the system ceases to be operative; because the nucleus of this system is a line of surveillance whose impedance changes in a characteristic manner when an incidence occurs. Of application in the detection and localization of sabotajes in security facilities. (Machine-translation by Google Translate, not legally binding)
