In the N2 ORS® system, the interoperability of the equipment (connection between the control panel, sensors, generators, valves, warning devices, etc.) is provided through protocol-based data exchange. This requires particular attention during the design phase to verify the transmission parameters, in order to avoid possible reflections, interference and random failures. The system is based on a dual closed-loop connection. The routing of the cables is designed in such a way that only a single part of the loop can be damaged: indeed, for each of the two branches in a single loop, the routing of the cables is differentiated from the routing of the other branch. This means that any damage to one of the two branches does not affect the other.
The power supply is also made up of a dual-loop connection. The operating principle is identical to the system used for data transmission. Furthermore, the power supply system has two sources: the primary power supply from the public mains network and the back-up supply provided by power packs. If the primary power supply is not available, the back-up supply starts up automatically. When the primary supply is once again available, it automatically takes over from the back-up system.
