Gräf & Meyer GmbH supplied a highly modern voice alarm and public address system for the Munich branch of TRETTER-Schuhe. Professional installation and commissioning were carried out by our partner PHOENIX Professional Audio.

The system meets current fire protection standards (EN 54‑16 / EN 54‑4), offers flexible zone control, and ensures clear announcements in both daily operations and emergency situations.

The store now benefits from maximum safety, optimized speech intelligibility, and easy operation, ensuring that both customers and staff are always well-protected and informed.
