The BVRDNET provides a digital networking solution for the
VIGIL EVAS BVRD2M & BVRD2M4 DSP-controlled voice alarm
routers.
The BVRDNET is a factory fitted option for the BVRD2M &
BVRD2M4 and enables upto 126 systems to be networked
together.
The systems are fully monitored and connected in a loop
configuration. The network will continue to function in the event
of cabling damage at a single location.
The network can be either Copper, Multi Mode Fibre, Single
Mode Fibre or a combination of both using the BVRDCIF,
BVRDFIF and BVRDFIFS interface modules.
Two RS485 communication ports and upto 14 concurrent audio
channels can be distributed around the network.
Typical maximum distances for copper connection are 300m for
“slow speed” providing six concurrent audio channels and 200m
for “fast speed” providing 14 concurrent audio channels.
The typical maximum distance for a multi mode fibre connection
is 3km and 4km for a single mode fibre connection.
