The BCH-712 EN is a compact and powerful A/B wall-mounted loudspeaker, certified according to EN 54-24:2008 by a notified certification body. It also complies with DIN EN 50849 / VDE 0828, VDE 0833-4, and BS 5839 Part 8, making it ideal for life-safety paging and evacuation systems.

Equipped with two separate speaker drivers and two 100 V transformers, the unit enables A/B line separation within a single housing – perfect for use in escape routes, stairwells, and other critical areas requiring redundant audio paths.

The shock-resistant MDF enclosure with a robust perforated steel grille is engineered to be resonance- and vibration-free. Integrated ceramic terminals, thermal fuses, and moisture-protected speaker cones provide enhanced operational safety. The unit meets IP 54 protection class and features a quick-mount spring-lock system for easy wall installation.
