INSTALLATION MANUAL
CEILING MOUNT FIRE DOME SPEAKER
PC-1867F, PC-1867FC
Thank you for purchasing TOA’s Ceiling Mount Fire Dome Speaker.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
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
Indicates a potentially hazardous situation which,
if mishandled, could result in death or serious
personal injury.
• 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.
• 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 moderate or minor
personal injury, and/or property damage.
• 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.
• 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 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.
• 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.
• 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-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.
3. INSTALLATION
ø156 ±3 mm
Step 1. Using the supplied paper pattern as a guide, open a 156 mm
±3 mm mounting hole in the ceiling panel.
Ceiling
Max. 30 mm
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 4. Feed the speaker cable through the rubber grommet into the dome interior.
Step 5. Press the fire dome assembly into the previously prepared hole in the ceiling.
Each leg should settle
on the collar.
Push up the dome assembly pressing
the bracket sides with your fingers.

Caution
Since the dome mounting bracket is not placed on the
ceiling panel at this stage, as shown in the above figure,
the dome could fall if released, so continue to provide
manual support.
Step 6. Push in the dome mounting thumbnut.

Firmly push the thumbnut and screw shaft
in the direction indicated by the arrow.

The legs of the dome mounting bracket will pop open
and settle on the back surface of the ceiling panel,
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.

Note: ‌Hook the two ends of one of the speaker
mounting springs into the hooks in the fire dome
during connection.

corresponding hook in the dome, then push the speaker
up into the fire dome.
Caution
Do not press directly on the front grille, as the grille
could become dented or damaged.

4. INSTALLING THE SAFETY WIRE (prepared separately by the installer)
Step 1. Tie one end of the safety wire around the terminal fitting
metal.
Note: ‌When using a bare safety wire, wrap insulation
tape around it to prevent electrical contact with
the connection terminals, transformer taps, or
other electric parts.
Step 2. Make a cut in the rubber grommet with a knife or a
screwdriver, then run the safety wire through it.
Step 3. Tie snap ring around a secure channel bar or suspension
bracket.
Step 4. Feed the speaker cable through the rubber grommet into
the dome interior.
Step 5. Secure the fire dome assembly in the ceiling, then
connect the speaker cable to the terminal block.
Step 6. Attach the speaker to the fire dome.
Note: ‌If the speaker cable and safety wire are too long,
to prevent them from being tangled inside the fire
dome, gently push them back out of the fire dome
so the rubber grommet does not get removed.
