Description
The BVRD2M4 is a four-zone voice alarm router, with the same great features as the BVRD2M, designed for smaller installations and networked decentralized systems.
Key Features
- DSP control.
- Possible to monitor up to four dual (A&B) circuits.
- Four electronically balanced inputs. Input one is configurable 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.
- Fully monitored surveillance at either 30Hz or 20kHz (faults are recorded in the history log).
- 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. Settings and messages are changeable (password protected) via the USB2 port.
- Nine selectable chimes / pre-announcement tones of up to eight seconds in length.
- Up to 126 EWS routers can be networked using fibre or copper to produce a truly sophisticated VA network.
- Message synchronization, even on a decentralised system.
- Ambient noise sensing (using optional ambient noise sensing microphones).
- Amplifier
