INSTALLATION MANUAL

CEILING MOUNT FIRE DOME SPEAKER

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.

• Use only the specied amplier output voltage

and impedance, as exceeding the specied limits

could result in re 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 specied 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

amplier 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 re.

• 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 re.

• 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.

Indicates a potentially hazardous situation which,

if mishandled, could result in death or serious

personal injury.

WARNING

Indicates a potentially hazardous situation which,

if mishandled, could result in moderate or minor

personal injury, and/or property damage.

2. GENERAL DESCRIPTION

TOA's PC-1860F, PC-1860BS, and PC-1860BS-C

Ceiling Mount Fire Dome Speakers feature an iron-

made dome that prevents the re from spreading in

the ceiling in case of re.

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-1860F comes with a push-in type input terminal

block that permits one-touch cable connection as well

as bridging and branch wiring, while the PC-1860BS/

PC-1860BS-C are provided with a steatite terminal

block of screw type.

The PC-1860BS/PC-1860BS-C are certied according

to the European Standard EN 54-24: 2008 and

compliant with the British Standard BS 5839-8: 2008.
