Thank you for purchasing TOA's Wall Mount Speaker. 
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.

Indicates a potentially hazardous situation which,
if mishandled, could result in death or serious
personal injury.

Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.

• Before installation or use, be sure to carefully read

all the instructions in this section for correct and
safe operation.

• Be sure to follow all the precautionary instructions

in this section, which contain important warnings
and/or cautions regarding safety.

• After reading, keep this manual handy for future

reference.

• Install the unit only in a location that can

structurally support the weight of the unit and the
mounting bracket. Doing otherwise may result in
the unit falling down and causing personal injury
and/or property damage.

• Do not use other methods than specified to mount

the bracket. Extreme force is applied to the unit
and the unit could fall off, possibly resulting in
personal injuries.

• Tighten all screws securely. If any is loosely fixed,

this may cause the speaker cabinet or baffle to fall,
resulting in personal injury.

• To avoid electric shocks, be sure to switch off the

amplifier's power when connecting speakers.

• Do not operate the unit for an extended period of

time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.

• Do not stand or sit on, nor hang down from the unit

as this may cause it to fall down or drop, resulting
in personal injury and/or property damage. 

• Constructed with metal cabinet, the speakers are

ideal for use in a voice evacuation system.

• Can be surface- or flush- mounted to the wall. 

• Either concealed in-wall wiring or exposed wiring

can be used for speaker cable connection.

• The speaker structure of direct wall-mounting with

screws prevents the speaker from falling easily
even if an outward force is applied to. 

• The input impedance can be easily changed by

changing the tap position of the transformer.

• Two built-in 6-inch double cone speaker units

deliver high quality sound.

• Two ceramic screw terminal blocks (1 cable to 1

connection type) make bridge connection easier.
(BS-680FC)

• The push-in type input connector makes cable

connections easy and allows bridge wiring. (BS-
680F)

• The BS-680FC complies with British Standard

5839 part 8.
