Baldwin Boxall Ambient Noise Weatherproof Sensor BVRAMBIP

Baldwin Boxall Ambient Noise Weatherproof Sensor BVRAMBIP

Baldwin Boxall Ambient Noise Weatherproof Sensor BVRAMBIPWhen designing a voice alarm system for areas of variable levels of ambient noise which could cause problems with audibility noise sensors should be included. Correctly placed ambient noise sensors will ensure that all announcements are clearly heard.Key FeaturesTwo versions are available BVRAMB - standard version. BVRAMBIP - IP65 rated version.Monitors the ambient noise in a given area.Automatically adjusts the power of the amplifiers depending on noise level.When the area is at its quietest the level of the announcements or music will reduce.During busynoisy periods the volume level adjusts to suit.Used in conjunction with a BVRDCI CANBUS interface module which connects to the VIGIL EVAS routers.Uses a dynamic microphone capsule the output of which is amplified and converted to produce a variable current.This output is used by the BVRDCI module to produce a voltage that is proportional to the ambient noise.Band pass filtering ensures that the system only responds to ambient noise affecting the intelligibility of announcements.An on-board surveillance tone generator permanently monitors the microphone capsule. A system fault will be indicated should the microphone capsule or on-board amplifier fail.The BVRAMB includes an option to allow one of three response speeds to be selected SLOW - the system will only respond to an average change of ambient noise. MEDIUM - suitable for most installations. FAST - the system will react to short duration changes in ambient noise.Two units can be wired in parallel on the same input to monitor the ambient noise over a larger area.

Baldwin Boxall VIGIL2 EVAS Router with 8 Inputs and 7 Audio Outputs BVRD2M

Baldwin Boxall VIGIL2 EVAS Router with 8 Inputs and 7 Audio Outputs BVRD2M

Baldwin Boxall VIGIL2 EVAS Router with 8 Inputs and 7 Audio Outputs BVRD2MThe VIGIL EVAS BVRD2M DSP-controlled router is well-established and has been installed in many prestigious sites Worldwide.VIGIL EVAS routers are feature rich and in common with all Baldwin Boxall products are built to a very high standard. A voice alarm system MUST work when needed during an emergency such as a fire. Baldwin Boxalls voice alarm systems are renowned for their reliability and can be installed with confidence.There are two routers in the EVAS range the BVRD2M and the BVRD2M4 as well as slave router options. The modular style of the VIGIL2 voice alarm system offers great choice and flexibility. It is as suitable for small systems as it is for very large networked systems.Key FeaturesDSP control.Eight electronically balanced inputs. Inputs one and two are configurable with all call processor bypass and are normally reserved for fire microphones. All inputs have both independent priority and level settings.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 limitercompressor enhancing the intelligibility of the system.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 real-time 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.Nine selectable chimes pre-announcement tones of up to eight seconds in length.Expandable with BVRD2S slave router and CANBUS modules.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.Amplifier changeover one in ten.Two RS485 ports for networking microphones etc.Zone grouping and barring on BVRD voice alarm controller.
