VIGIL2 DSP Networking

Digital Networking with single-mode or multi-mode Fibre, Copper, or Combination.

BVRDNET provides a digital networking solution for the VIGIL EVAS DSP-controlled Voice Alarm system routers.

Connected in a loop configuration, the network can employ either copper cable, fibre, single-mode or multi-mode, or any combination. No matter which cabling type is used, the network remains fully monitored and continues to function even in the event of cable damage at a single location.


  • Connected in a loop configuration
  • Continues to function in the event of cabling damage at a single location
  • The network can be copper, multi mode fibre, single mode fibre or any combination of these
  • Six (slow speed option) or fourteen (fast speed option) concurrent audio channels with two RS485 channels
  • Network status indicators
  • Fully monitored
  • Optional system reset feature
  • Up to 126 systems can be digitally networked – multiple copper / fibre loops required for systems greater than 36 nodes
  • The controller (BVRDNET/BVRDNET2M4) is factory fitted and configured from the router’s menu
  • Slow speed option providing six concurrent audio channels with two RS485 channels
  • Fast speed option providing fourteen concurrent audio channels with two RS485 channels
  • Audio bandwidth is 30Hz-20kHz
  • Typical maximum distance:
    • Copper – 300m at slow speed and 200m at fast speed. (Greater distances are possible with some cable types.)
    • Multi-mode fibre – for slow and fast speed connections of 3km (OM1), 2Km (OM2) and 2km (OM3)
    • Single-mode fibre – for OS1 is 2km and for OS2 is 4km
