The VM-2000 Series' cost-effectiveness allows installation to be basic at first, then expanded as particular requirements dictate. Optional accessories and related equipment are available to meet specific requirements and enhance a unit's operational scope. The VM-2000 Series conforms to most international emergency sound system standards and requirements such as IEC60849 (EN60849).
