Baldwin Boxall BV3ADIS VIGIL 3 Slave DC Line Monitoring Isolator/Changeover Mod

Baldwin Boxall BV3ADIS VIGIL 3 Slave DC Line Monitoring Isolator/Changeover Mod

The 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 Features

• Enables dual loudspeaker circuits to connect to a single amplifier
• Each BV3ADIS unit provides both A&B circuits for two amplifiers
• Up to 10 spurs per loudspeaker line
• The BV3ADIM master unit connects to a VIGIL3 amplifier
• Up to five BV3ADIS can be connected to one BV3ADIM
• Fitting five BV3ADIS enables broadcast and monitoring for up to twenty loudspeaker circuits
• The modules plug directly together
• Utilises 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 circuit
• In the event of an amplifier failure, reserve amplifiers will automatically operate
• With five BV3ADIS fitted, a one-in-ten amplifier changeover ratio is enabled
• Reduces rack size and cost for large voice alarm systems
• Earth leakage detection
