You won’t need additional sensors or electrical sensor components since FOTAS system uses a whole fiber optic cable as an acoustic sensor. Only one FOTAS box installed in the system room and its fiber optic cable is enough to know what is going on in the environment. Other point sensors need an additional power supply at the point they are installed whereas FOTAS doesn’t. Normally perimeters or pipe networks are watched by humans or systems which need continuous power; but with fiber optic sensing we don’t need such time and money consuming methods anymore. Another advantage of fiber optics is that they are very lightweight and also they don’t need an additional monitoring once they are installed.
