Digital Networking

The BVRDNET range provides a digital networking solution for the VIGIL EVAS DSP-controlled voice alarm routers (BVRD2M and BVRD2M4). The BVRDNET (or BVRDNET2M4) is factory-fitted to the EVAS router. Connected in a loop configuration, the network can be copper (using BVRDCIF), fibre (using BVRDFIF) or a combination of both. Fully monitored, the network continues to function in the event of cabling damage at a single location. BVRDNET & BVRDNET2M4 Slow speed option providing six concurrent audio channels with two RS485 channels Fast speed option providing fourteen concurrent audio channels with two RS485 channels BVRDCIF The BVRDCIF is a DIN rail mounted connection to copper network sections. (Two BVRDCIF required per BVRDNET/2M4) Typical maximum distance of 300m at slow speed and 200m at fast speed. (Greater distances possible with some cable types) BVRDFIF The BVRDFIF is a DIN rail mounted connection to fibre network sections. (Two BVRDFIF required per BVRDNET/2M4) Typical maximum distance of 3km at slow or fast speed ST transmit connector and ST receiver connector for multimode fibre (62.5/125 cable)
