BVRD2M4 Router - Baldwin Boxall
Router
BVRD2M4
Certified to BSEN54
The BVRD2M4 is a four-zone voice alarm
router, with the same great features as the
BVRD2M, designed for smaller installations
and networked decentralised systems.
VIGIL 2
FEATURES:
•
DSP control.
•
Possible to monitor up to four dual (A&B) circuits.
•
Four electronically balanced inputs. Input one is con­
figurable with ‘all call’ processor bypass and is normally
used for the fire microphone in voice alarm systems. All
inputs have both independent priority and level settings,
allowing for dual mode; emergency and normal page.
•
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.
•
Three band parametric plus bass and treble equalisation
on all inputs (with limiter/compressor), enhancing the
intelligibility of the system.
•
Four audio electronically balanced (0dBM) outputs with
ten band parametric equalisation and audio delay of up to
one second.
• Ambient noise sensing (using optional ambient noise
sensing microphones).
• Amplifier changeover for up to three zones (using optional
relay board, product code BVRD2M4ACO).
• Two RS485 ports for networking, microphones, etc.
• Zone grouping and barring on BVRD voice alarm
controller.
HARDWARE FACILITIES:
Audio:
•
4 x electronically balanced line -20dB audio inputs (input 1
with processor bypass).
•
‘All call’ failsafe emergency evacuate message
embedded in main processor in the event of DSP failure.
•
4 x electronically balanced 0dBM audio outputs.
• Fully monitored surveillance at either 30Hz or 20kHz
(faults are recorded in the history log).
•
4 x opto-coupled sounder circuit programmable inputs
from the fire detection system.
• 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.
•
8 x analogue voltage sensing inputs for monitored input
access, ambient noise sensors, remote volume controls.
•
8 x surveillance inputs for monitoring 100V loudspeaker
lines (using BEL1 modules).
• Six flash stored (57 second) messages with independent
level, surveillance and timing. Settings and messages are
changeable (password protected) via the USB2 port.
•
8 x NPN collector outputs 40V @ 100mA for busy, etc.
•
1 x volt free relay changeover contact for common fault.
• Nine selectable chimes / pre-announcement tones of up
to eight seconds in length.
Serial Ports:
Control Outputs:
•
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.
• Up to 126 EVAS routers can be networked using fibre or
copper to produce a truly sophisticated VA network.
• Message synchronisation, even on a decentralised
system.
