The BCH-620 is a powerful enclosure loudspeaker designed for voice evacuation systems requiring A/B wiring in compliance with DIN EN 60849 / VDE 0828. Featuring two high-performance 5x3 wide-range speakers with integrated tweeter cones and dual transformers, this unit allows for space-efficient, secure A/B line separation within a single housing.

The housing is made of coated MDF wood and is acoustically optimized to be completely resonance- and vibration-free. A rear panel with spring latch simplifies installation, and pre-drilled holes allow for either horizontal or vertical mounting — making this speaker adaptable to diverse environments.

An optional BS-5839 configuration is available, featuring a ceramic terminal, thermal fuse, and fire-resistant cable. Additionally, custom paint finishes can be provided to match architectural requirements.
