TABLE OF CONTENTS

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.

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.

• Since the unit is designed for in-door use, do not

install it outdoors. If installed outdoors, the aging of
parts causes the unit to fall off, resulting in personal
injury. Also, when it gets wet with rain, there is a
danger of electric shock.

• 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.

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

2. GENERAL DESCRIPTION AND FEATURES

The PJ-154BS is certified according to the European Standard EN 54-24: 2008, the International Standard
7240-24: 2010 and compliant with the British Standard BS 5839-8: 2008 14.8.
The PJ-154BS is a projection speaker designed for wall or ceiling installation.
Considered in architectural design, it can blend in with lighting equipment.
The supplied swivel bracket allows flexible speaker angle adjustment.
The speaker is driven on high-impedance (100 V and 70 V) line, and its input power (impedance) can be
easily switched.

Note

Never dismantle the PJ-154BS in any way even for repainting reason. Since the PJ-154BS is certified in the
form of complete assembly by the above-mentioned standards, it does not meet these standards if
dismantled.

3. IMPEDANCE CHANGE

The input power (impedance) is factory-preset to 15 W (670 Ω)
for 100 V line and 7.5 W (670 Ω) for 70 V line.
When changing this setting, use a standard screwdriver to rotate
the rotary switch on the upper side of the speaker to the desired
position.

Notes

• Switch off the amplifier's power when changing the input
power.

• No sound is output when the switch is set to the OFF position.

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

CAUTION

• 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.

• 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.

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.

4. INSTALLATION

Note

Be sure to make speaker cable wiring via the supplied terminal box. (Refer to Step 3 on the next page.)
The way of wiring without using the terminal box does not fulfill the standards requirements.

Step 1. Secure the swivel bracket to the ceiling or wall with 3 screws.

Loosen the safety screw (for fall prevention) as shown below.

Before installation

Step 2. Mount the speaker to the swivel bracket.

Be sure to remove the Speaker Cord protective
sheet used for packing material.

2-1. Loosen the speaker fixing screws.

Note

These screws are pre-screwed into the bracket at the factory.
Loosen them so that they can slip into the swivel bracket's screw slots.

2-2. Slip 2 speaker fixing screws into the swivel bracket's screw slots.

2-3. Tighten the speaker fixing screws and safety screw.

Note

Ensure that the safety screw is fit into the given hole in the speaker bracket.

Before installation

Be sure to adjust the speaker angle within the
range shown at right. Installing the speaker at
an angle exceeding this range does not meet
the standards requirements.

Note

Loosen the safety screw until it's tip does not stick out from the bracket surface.
If the screw tip sticks out, this obstructs the insertion of the speaker bracket in Step 2.

Tapping screw 4 x 16 (accessory)

Note

If these screws are not appropriate for the ceiling material,
separately prepare the proper screws.
