Baldwin Boxall BV3ADIS VIGIL 3 Slave DC Line Monitoring IsolatorChangeover ModThe DC line monitor isolator units are CANBUS modules for the VIGIL voice alarm systems with VIGIL3 amplification consisting of two components BV3ADIM and BV3ADIS.Key FeaturesEnables dual loudspeaker circuits to connect to a single amplifierEach BV3ADIS unit provides both AB circuits for two amplifiersUp to 10 spurs per loudspeaker lineThe BV3ADIM master unit connects to a VIGIL3 amplifierUp to five BV3ADIS can be connected to one BV3ADIMFitting five BV3ADIS enables broadcast and monitoring for up to twenty loudspeaker circuitsThe modules plug directly togetherUtilises DC line monitoring techniques therefore BEL1 end of line monitoring is not required. Please refer to system requirements.Failure of either the A or B circuit from one amplifier will not effect the other circuitIn the event of an amplifier failure reserve amplifiers will automatically operateWith five BV3ADIS fitted a one-in-ten amplifier changeover ratio is enabledReduces rack size and cost for large voice alarm systemsEarth leakage detection
