Baldwin Boxall Ambient Noise Sensor BVRAMB

Baldwin Boxall Ambient Noise Sensor BVRAMB

Baldwin Boxall Ambient Noise Sensor BVRAMBWhen 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.
