The dawn of a new era in public address and voice alarm systems is here with Variodyn D1 – the only system you need for today’s complex world of public safety!
The DOM4-8 is the central control element of the Variodyn D1. It is equipped with 4 independent audio outputs to access 4 channels, and operates 2 zones (8 circuits total). Any complex system configuration can be implemented through the networking of multiple DOM4-8s via the Ethernet.
