Eaton’s FHF-BT Loudspeaker System is an intrinsically safe and cost-efficient solution for speech, signaling, and prestart warnings. This robust, modular, and scalable system is designed to cover long distances and can be seamlessly integrated into our Shaft Signaling System for communication between each level and the surface. It also supports communication along underground galleries and belt conveyors.

Equipped with two powerful speakers, it effectively withstands ambient noise and maximizes sound coverage, ensuring clear and reliable communication in any environment.

Eaton’s FHF-BT WL200 Dispatcher System for underground communication is designed to streamline and enhance your communication infrastructure by organizing loudspeaker, telephone, and wireless systems seamlessly. This advanced system offers a multitude of communication options and combinations:

• Authorized communication between each line from the operator desk at the surface.
• Direct communication from the central desk to the lines and vice versa.
• General messages to the entire mine (all lines) from the control desk. 
• General announcements or flashlight alarm signals to individual lines, groups of lines, or the entire mine.
• Connect single communication lines into a complete, cohesive network.

Eaton’s FHF-BT iVT3 is an intrinsically safe analogue telephone system, designed for reliability and safety. It can be enhanced with additional features such as external loudspeakers and signaling devices for call signals and alarm announcements, with the capability to cover distances up to 12 km.

The system includes battery-buffered telephones, ensuring continuous communication even in high methane gas (CH4) concentrations and during power shutdowns.
