• 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.
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.

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.
