Open system architecture

The open, modular all-in-one system for media technology as well as public address, electroacoustic emergency and voice alarm systems has a multitude of different interfaces for maximum flexibility when connecting other systems. This helps immensely when integrating fire alarm and building management systems/controls or monitoring non-acoustic systems.

Secure interfaces

Intelligence also means that you have direct access to user guidance and system feedback with guaranteed error detection when interfaces suffer interruptions. The automatic and continuous monitoring of these interfaces ensures the system’s prescribed availability even in emergencies:
