The VARES-1500 voice alarm system is a compact and powerful all-in-one solution designed for small to medium-sized applications. It combines the simplicity of a conventional standalone system with the scalability and networking advantages of a distributed system architecture.

The system is expandable to support up to 36 monitored speaker lines in single-channel mode or 18 lines in dual-channel operation. It integrates 600 W or 300 W amplifier capacity and includes an active backup amplifier to ensure system redundancy. Up to 255 control and display units can be connected via a ring topology using peer-to-peer communication—ideal for decentralized building infrastructures.

To maintain system integrity, VARES-1500 continuously monitors all components, including mains power, batteries, amplifiers, microphones, and speaker lines with end-of-line (EOL) functionality. The built-in text module and digital voice memory support automated playback of alert and evacuation messages. With integrated pre- and post-processing software, volume control, routing, mixing, switching, and prioritization can be flexibly managed.
