TOA BS-680U 6" Wall-Mount Metal Box Emergency Broadcast Speaker

Constructed with metal cabinet, the TOA BS-680U speaker is great for use in a voice alarm system. It can be surface- or flush- mounted to the wall, with either concealed in-wall wiring or exposed wiring for speaker cable connection. The structure of direct wall-mounting with screws prevents the speaker from falling easily even if an outward force is applied to it. Input impedance can be easily varied by changing the tap position of the transformer. The onboard 16cm double cone speaker unit provides high quality sound. The push-in type input connector makes cable connections a breeze, and allows bridge wiring to be used. The BS-680U is certified to UL 1480 UUMW and ULC-S541 standards, and is designed for indoor use only.
