Constructed with metal cabinet, the speaker is ideal for use in a Voice Evacuation System. The speaker can be surface- or flush-mounted to the wall. Either concealed in-wall wiring or exposed wiring is possible. The input impedance can be easily changed Two ceramic screw terminal blocks (6 cable to 16 connection type) make bridge connection easier. A built-in 1-inch (1 cm) double cone speaker unit delivers high quality sound.
The BS-680FC is certified with EN 54-24.
