The farm anti-theft system protects tractors as well as trailers, machines and tools, which would be otherwise difficult to secure. It is composed of an alarmed chain which is goes across the objects you need to secure, just like a bicycle chain: a thief must cut the chain to steal the object.
This alarmed chain is an armoured cable with sensitive core in plastic fiber. A light signal, generated by an analysing board, goes through it. An alarm is only triggered when the chain is cut or bent: this system allows early intervention in case of attempt of theft. It is not sensitive to vibrations, so it is free of false alarms.
The analysing board can be connected to any alarm panel with an NC contact, so the alarm signal is properly managed (with a connection to a siren, phone call/sms, etc.)
The armoured cable is supplied in patch-cords of different lengths, (usually a few tens of meters), which can be joined together, so that a single sensitive loop can easy protect many machines and tools, also of considerable dimensions. In this way, one single chain can protect many objects, including trailers, tools, equipment, doors, tanks, temporary fences, etc.
This anti-theft system is suitable for the farm environment, because you can walk on the cable, it is resistant to water and dirt, and, above all, because it is not sensitive to vibrations, due to small animals, for example.
