ELISA III-IP – the new generation of software-based PA systems

ELISA III-IP is a new generation of public address systems for use in railway applications. The product line combines a smart sound processor with a high-quality amplifier and full network capability.

Smart platform for sound and safety

As a smart platform, ELISA III-IP assumes the tasks of a cost-effective software-based passenger information system as well as of voice alarm functions according to EN 54-16. Safety-related passenger warnings are issued immediately and acoustically reliable in case of emergency.

Load functional apps according to your needs – without any hardware change.

Cut your maintenance cost with our Zero Configuration hardware replacement approach: With only a few handgrips a device is changed.

Implement scalable systems for up to 600 Watt per A/B line – as a resilient or even fully redundant high available design.
