VOICE ALARM
BVRD2M ROUTER
The BVRD2M DSP-controlled router is well-established and has been installed in many
prestigious sites Worldwide.
FEATURES:
•
DSP control.
•
Eight electronically balanced inputs. Inputs one and two
are configurable with ‘all call’ processor bypass and are
normally reserved for fire microphone(s). All inputs have
both independent priority and level settings.
•
• Up to 126 EVAS routers can be networked using fibre or
copper to produce a truly sophisticated digital VA network.
• Message synchronisation, even on a decentralised
system.
• Ambient noise sensing.
Up to fifteen priority levels are available. If two concurrent
routes are set at the same priority they will be treated on a
‘first come first served’ basis. Priorities are changeable.
• Amplifier changeover (one in ten).
•
Three band parametric plus bass and treble equalisation
on all inputs (with limiter/compressor), enhancing the
intelligibility of the system.
• Zone grouping and barring on BVRD voice alarm
controller.
•
‘All call’ failsafe emergency message generator (twenty
second EPROM).
•
Seven electronically balanced audio outputs with ten
band parametric equalisation and audio delay of up to
one second.
• Fully monitored surveillance at either 30Hz or 20kHz
(faults are recorded in the history log). All inputs, outputs
and DSP messages can be aurally monitored through a
loudspeaker on the front panel.
• Built-in realtime clock enables detailed logging and
reporting, including detected faults. Indicates time,
date, month and year. Also used for night time volume
reduction, timed message trigger and to control external
inputs. The history log can be accessed via the USB2 port
on the front panel.
• Six flash stored (57 second) messages with independent
level, surveillance and timing. (For longer, non-critical
messages, up to three can be combined.) Settings and
messages are changeable (password protected) via the
USB2 port.
• Two RS485 ports for networking, microphones, etc.
HARDWARE FACILITIES:
Audio:
•
8 x electronically balanced line -20dB audio inputs (inputs
1 and 2 with processor bypass).
•
‘All call’ failsafe emergency message generator (20
second EPROM) in the event of DSP failure.
•
7 x electronically balanced 0dBM audio outputs.
•
2 x opto-coupled sounder circuit programmable inputs
from the fire detection system.
•
6 x analogue voltage sensing inputs for monitored input
access, ambient noise sensors, remote volume controls.
•
3 x contact inputs for unmonitored zone access or PTT.
Control Outputs:
•
6 x NPN collector outputs 40V @ 100mA for busy, etc.
•
1 x volt free relay changeover contact for common fault.
Serial Ports:
•
2 x RS485 half-duplex ports for communicating to control
microphones, fire detection systems, network control,
fault reporting.
•
1 x front panel USB2 port to configure the system, fault
diagnostics, fault reporting, message download, etc.
• Nine selectable chimes / pre-announcement tones of up
to eight seconds in length.
•
Expandable with BVRD2S (slave router) and CANBUS
modules.
