MEDC DB20C Exde, weather-proof Ceiling Speaker

The MEDC DB20C delivers clear and reliable voice announcements in hazardous and demanding industrial environments. Designed for ceiling-mounted installation, it provides an effective public address and alarm notification solution for onshore and offshore oil, gas, petrochemical, and marine applications.

Furthermore, the DB20C is suitable for use in potentially explosive atmospheres and offers a power rating of up to 8W, ensuring clear audio performance even in challenging operating conditions. Its compact design fits into ceiling voids with limited space while maintaining an attractive appearance that blends seamlessly into the surrounding environment.

MEDC has also developed a lightweight, patented mounting system that allows engineers to install the speaker quickly without tools. The self-supporting and self-locking design mounts directly into ceiling tiles between 0.5mm and 55mm thick, while the twist-fit support and locking grille provide access from above or below the ceiling. As a result, installers can fit either the speaker or ceiling assembly first, simplifying installation and maintenance.
