Toa PC-1867FC User Manual
1. SAFETY PRECAUTIONS
• Be sure to read the instructions in this section
carefully before use.
• Make sure to observe the instructions in this
manual as the conventions of safety symbols and
messages regarded as very important precautions
are included.
• We also recommend you keep this instruction
manual handy for future reference.
• 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 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.
• 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.
• To avoid electric shocks, be sure to switch off the
amplifier power when connecting the speaker.
• 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.

CEILING MOUNT FIRE DOME SPEAKERS
INSTALLATION MANUAL
2. GENERAL DESCRIPTION (Patent pending)
TOA's PC-1867F and PC-1867FC Ceiling Mount Fire Dome Speakers feature 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-1867F comes with a push-in connector that permits one-touch cable connection as well as bridging
and branch wiring, while the PC-1867FC is provided with a steatite terminal block of screw type.
The PC-1867FC is certified according to the European Standard EN 54-24: 2008 and compliant with the
British Standard BS 5839-8: 2008.
WARNING
Indicates a potentially hazardous situation which,
if mishandled, could result in death or serious
personal injury.
CAUTION
Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.
3. INSTALLATION
Step 1. Using the supplied paper pattern as a guide, open a 156 mm
±3 mm mounting hole in the ceiling panel.
Step 2. 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.
Step 3. Loosen the dome mounting thumbnut.

providing the dome with partial support. If released, a
gap behind the collar of the dome will result (A).
Step 7.
Turn the dome mounting thumbnut clockwise to tighten and firmly secure the dome to the ceiling panel.
Step 4. Feed the speaker cable through the rubber grommet into the dome interior.
