• Fitting five BVRDADIS enables broadcast and monitoring for up to twenty loudspeaker circuits.
• The modules plug directly together.
• In the event of an amplifier failure, reserve amplifiers will automatically operate.
• With five BVRDADIS fitted, a one-in-ten amplifier changeover ratio is enabled.
• Reduces rack size and cost for large voice alarm systems.
