1. SAFETY PRECAUTIONS
• 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.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
WARNING
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
When Installing the Unit
• Refer all installation work to the dealer from whom
the speaker was purchased. Installation work
requires extensive technical knowledge and
experience. The speaker may fall off if incorrectly
installed, resulting in possible personal injury.
• Install the speaker only in a location that can
structurally support the full weight of the unit and
mounting bracket. Doing otherwise may result in
the speaker falling down and causing personal
injury and/or property damage.
• When installing the speaker in the snowy area,
take appropriate measures to prevent snow from
lying on the speaker. If the snow lies on it, the
speaker may fall, causing personal injuries.
• Do not use other methods than specified to install
the speaker. Extreme force is applied to the
speaker and the speaker could fall off, possibly
resulting in personal injuries.
• Use screws that are appropriate for the ceiling's or
wall's material and structure. Failure to do so may
cause the speaker to fall, resulting in material
damage and possible personal injury.
• Ensure that all screws are securely tightened. If
they are loose after installation, the speaker could
fall down, possibly resulting in personal injury.
• Do not mount the speaker in locations exposed to
constant vibration. The speaker or its mounts can
be damaged by excessive vibration, potentially
causing the speaker to fall, which could result in
personal injury.
2
• Do not use anti-rust lubricant. If it contacts resin or
rubber parts, they could deteriorate and cause the
speaker to fall, possibly resulting in personal injury.
• Avoid installing the speaker near seaside or in
locations exposed to corrosive gas. The speaker or
its parts may be subject to corrosion, which might
cause it to fall or result in personal injury.
• Do not install the speaker in indoor swimming pools
or such locations where liquid chemicals are used.
The parts deteriorate if corroded, causing the
speaker to fall, which could result in personal
injury.
When the Unit is in Use
• If any of the following irregularities occurs,
immediately switch off the amplifier's power, and
inform the shop from where the speaker was
purchased. Further using the speaker may result in
fire or electric shock.
· If you detect smoke or a strange smell coming
from the speaker
· If water or any metallic object gets into the
speaker
· If the speaker falls, or the speaker case breaks
• To prevent a fire or electric shock, never open nor
remove the speaker case. Refer all servicing to
your nearest TOA dealer.
CAUTION
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
When Installing the Unit
• Avoid touching the speaker's sharp metal edge to
prevent injury.
• To avoid electric shocks, be sure to switch off the
amplifier's power when connecting speakers.
When the Unit is in Use
• Do not operate the speaker for an extended period
of time with the sound distorting. Doing so may
cause the speaker to heat, resulting in a fire.
• Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property
damage.
• Have the speaker checked periodically by the shop
from where it was purchased. Failure to do so may
result in corrosion or damage to the speaker or the
mounts that could cause it to fall, possibly causing
personal injury.
2. GENERAL DESCRIPTION AND FEATURES
TOA's SC-615BS Paging horn speaker features an aluminum horn flare and stainless steel bracket for allweather durability. The TOA's unique oval shape horn enhances excellent speech clarity. Other feature
includes a newly developed diaphragm employing special heat-resistant polyimide film to prevent the
diaphragm from absorbing moisture and deformation. High speaker efficiency has also been realized by
minimizing the gap produced when the diaphragm bobbin is installed in the magnetic circuitry slit. The SC615BS is certified to the European Standard EN 54-24: 2008 and the International Standard ISO 7240-24:
2010, and is compliant with the British Standard BS 5839-8: 2008.
• Compact, highly intelligible speaker suited to public address announcement applications.
• Stainless steel bracket and hardware (screws, bolts), and powder-coated horn ensure superb
weatherproofing and corrosion-resistance.
• Shock-resistant aluminum oval horn.
• Certified to EN 54-24, and ISO 7240-24, and compliant with BS 5839-8.
• Equipped with a large steatite terminal block of screw type and thermal fuse.
• Provided with a cable gland on the terminal cover.
• One cable gland can be added, enabling bridge wiring.
• Impedance change available by a rotary switch located inside the terminal cover.

3. IMPEDANCE CHANGE
Input impedance is factory-preset to 670 Ω.
To change the impedance, change the rear panel-mounted rotary switch position using a standard
screwdriver.
Notes
• This speaker is designed to be used for high impedance applications (70 V/100 V). Never connect the
speaker to low impedance line.
• No sound is output from the speaker when the switch is set to the OFF position.
Caution
Never set the switch to "–" position for 100 V line operation, as doing so may result in damage to the speaker.

4. WIRING
The terminal cover is not mounted to the speaker unit when shipped from the factory.
Note
To complete speaker installation, be sure to attach the terminal cover after finishing cable connections.
If the unit is left without the terminal cover attached, water or moisture may get inside the speaker, causing the
unit malfunction.

Step 4. Attach the terminal cover.
Secure the terminal cover using the 4 supplied screws.
In this case, take care not to pinch the wiring, and check that the waterproof gasket is secured into
place.
Note
If wiring or the waterproof gasket is pinched between the terminal cover and the unit case, this causes
water or moisture to get inside the terminal cover.

4.2. When Bridge Connection is Required
Step 1. Punch a knockout hole.
Punch out the knockout on the terminal cover by tapping the center of
the knockout with a screwdriver or other tool.
Note
Clean burrs off the knockout hole after removing the knockout.

5. INSTALLATION PRECAUTION
• When installing the SC-615BS, be sure the drain hole is positioned
toward the ground. Otherwise, rainwater could enter the speaker
inside, and the aging of parts may cause the unit failure.

Less than 12 mm (0.47")
• Be sure that the bolt projection length from wall surface is less than 12 mm (0.47").
If the length is increased beyond 12 mm (0.47"), the bolt touches the speaker's terminal cover, causing the
speaker mounting angle to be limited.
Within 90°
• Do not install the speaker face-up from a horizontal plane. If water accumulates in the horn, this may cause
the speaker malfunction.
