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

2. GENERAL DESCRIPTION AND FEATURES
The PC-1869EN and PC-2369EN are certified according to the European Standard EN 54-24: 2008 and the
International Standard ISO 7240-24: 2010.
Integrated with a speaker unit and panel, the PC-1869EN and PC-2369EN Ceiling Mount Speakers are of
metallic construction and ideal for use in a voice alarm system. They feature spring catch mechanism for easy
speaker mounting to the ceiling. The input impedance can be easily changed by changing the tap position of
the transformer. The screw terminal (steatite) makes input cable connections easy and allows bridge wiring.
Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.
CAUTION
be damaged by excessive vibration, potentially
causing the speaker to fall, which could result in
personal injury.
• 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.

3. INSTALLATION
Step 1. Make a hole in the ceiling.
In the case of the PC-2369EN, marking-off pins provided on the mounting bracket will help draw the
circle of its diameter on the ceiling.
• PC-1869EN: 150 ±3 mm (5.91 ±0.12") diameter
• PC-2369EN: 200 ±3 mm (7.87 ±0.12") diameter
Step 2. Place the mounting bracket in the hole and secure it with the thumb screws in the 2 ceiling clamps.
Note: A suspension bolt may be used instead for fixing the mounting bracket (PC-2369EN only.)
Step 3. Hook one speaker spring (V-shaped spring) in the spring catcher of the bracket.
Step 4. Make wiring.
4-1. Connect the lead-in cable (the one from the amplifier) to the screw terminal. In this case, bend the
cables as shown below to facilitate the cable insertion into the input terminals.
When connecting the lead-out
cable (the one to the next speaker),
connect both the lead-in and leadout cables of the same polarity to
each corresponding input terminal.
Note*
Raise both pins, and draw a circle with the sharp
pin as its center and another pin as a scriber.
