The “SICURFLEX” protection system is a device that can be used in safety systems to protect photovoltaic panel installations, metal fences, perimeter wall as anti-jumping system, parks and garage protection. The system consists in an analysis unit called FLCEN and a sensor cable (FLEXCB) with a total length of no more than 500m. There are two different kinds of sensible cable, one that works under Tribo-electric principle, the other one that detects vibrations. The sensitive cable installation procedure change according to the type of protection to be implemented, thus being different according to the  type of application: solar panels, different net models (wire mesh, wooden protection, sheet, etc.). Two additional components, FLEXTR and FLEXCN, supplied with the product, should be used in addition to the sensitive cable and analysis unit for correct installation; FLEXTR is the end-of-line unit of the sensitive cable, whereas FLEXCN components are used both to connect FLEXCB to FLCEN and to create "non-sensitive" areas along the protected perimeter (ideal solution to bypass gates, doors, etc. along the path). The FLCEN analysis board generates an alarm (alarm relay with NC free contact) if the analogue signal detected causes the programmed alarm threshold to be exceeded.
