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.
WARNING

5. SPECIFICATIONS ......................................... 5
• Tighten each nut and bolt securely. Ensure that
the bracket has no loose joints after installation
to prevent accidents that could result in personal
injury.
• Avoid mounting the unit in locations exposed to
constant vibration. The mounting bracket can be
damaged by excessive vibration, potentially causing
the speaker to fall, which could result in personal
injury.
CAUTION
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.
• Use only the specified amplifier output voltage
and impedance, as exceeding the specified limits
could result in fire or other failures (high-impedance
applications).
• To avoid electric shocks, be sure to switch off the
amplifier power when connecting the speaker.
• To avoid accidental air explosions, do not use the
unit around gasoline, thinner or other combustibles.
• 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 unit. Extreme force is applied to the unit and
the unit could fall off, possibly resulting in personal
injuries.
• Avoid installing the unit in humid or dusty locations,
or in locations exposed to heaters, solvents, acid,
alkali, smoke, or steam, as excessive exposure to
these factors could result in the speaker falling off,
electric shock or fire.
• 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.
• Have the unit periodically checked by the shop
from where it was purchased. Failure to do so could
result in the speaker falling off due to damage or
corrosion to the speaker or its mounts, and possible
personal injury.
2. GENERAL DESCRIPTION
TOA's PC-1865BS Ceiling Mount Fire Dome Speaker features an iron-made dome that prevents the fire from
spreading in the ceiling in case of fire.
The speaker can be easily installed using the speaker mounting spring, and the dome can also be easily
mounted in the speaker mounting hole in the ceiling panel.
The PC-1865BS is provided with a steatite terminal block of screw type.
The PC-1865BS is certified according to the European Standard EN 54-24: 2008 and compliant with the British
Standard BS 5839-8: 2008.
3. INSTALLATION
Step 1. Using the supplied paper pattern as a guide, open
a 150 mm (5.91") ±3 mm (0.12") mounting hole in
the ceiling panel.

Step 3. Punch out the knockout hole in the fire dome, then
install the supplied cable entry rubber grommet in
the knockout hole.
Note: ‌The grommet's cable entry hole is covered
with a thin membrane. Cut a hole in the
membrane to match the size of the speaker
cable used.
