Baldwin Boxall DC Line Monitor BVRDADCThe Vigil BVRDADC is a loudspeaker line monitor and amplifier changeover unit for use with VIGIL amplifiers and the BVRD2M router. Each unit is supplied as a DIN rail-mounting module with screw terminals for connections to the amplifiers and loudspeaker lines. Connection to the BVRD2M is by CAN BUS ports. Each unit consists of ten channels that can be utilised for either dual or single circuit systems.For dual circuits ten working amplifiers five dual circuits and one standby amplifier can be accommodated. For single circuit systems ten working amplifiers ten single circuits and one standby amplifier are available. If an amplifier were to fail the BVRDADC automatically detects the faulty amplifier and switches over to a reserve amplifier until the fault has been rectified. A fault will be displayed on the BVRD2M front panel and also stored in the BVRD2M fault log.When the faulty amplifier has been replaced it is necessary to press the Fault Reset button on the front of the BVRD2M to restore the system and stop using the reserve amplifier. Each loudspeaker line including spurs must have an End of Line resistor fitted in parallel with the last physical loudspeaker on the line. All loudspeakers must be fitted with a DC Blocking capacitor. The BVRDADC monitors the integrity of the Loudspeaker Line by measuring a small DC current flowing through the End of Line resistors. Any change in this current indicates either a short circuit or open circuit condition on the loudspeaker line. Earth faults are also detected.
