Distributed intelligence and decentralised communication systems have made transparent buildings a reality. The times in which each sensor, motor and regulator had to be wired separately are long since over. TroxNetCom offers the most modern standardised decentralised communication systems as well as great potential cost savings. Compared with conventional independent systems, the new systems offer more safety, a better overview and more detailed information. These systems also enable a direct link to be established to the building control system without any extra programming work or relay contacts. Actual sensor interface - this is the full term which is abbreviated AS-i. It designates an European safety standard according to EN 50285. Today this system is already quite important for the industry. More than one million installed AS-i components are a clear indication of the system's significance. TROXNetCom-LON allows the easy use of complex fire- and smokedamper devices.
