BS-680U
Wall-Mount Speaker
APPEARANCE AND DIMENSIONAL DIAGRAM
DESCRIPTION
The BS-680U speaker has a strong, all-metal body, and are ideally
suited for voice alarm system applications. 6" double cone speaker
unit ensures high-quality sound. The BS-680U is certified to UL 1480
UUMW (Mass Notification System) and ULC-S541 standards. The
speaker can be quickly and easily installed in either a horizontal or
a vertical orientation. Either concealed in-wall wiring or exposed
wiring can be used for speaker cable connection. A push-in type
input connector allows easy cable connections and bridge wiring.
The selectable input impedance can be easily adjusted by changing
the top position of the unit’s transformer. Both flush-mounting and
surface-mounting are possible. The innovative structural design is
based on the Golden Ratio (1: 1.618), and also permits direct wall
installation with screws, making the speaker unit resistant to falling
even if outward force is applied to it.
