Thank you for purchasing TOA’s Ceiling Mount 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.
• 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.
CAUTION
Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.
• Avoid touching the unit's sharp metal edge to
prevent injury.
• To avoid electric shocks, be sure to switch off the
amplifier's power when connecting speakers.
• 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.
2. GENERAL DESCRIPTION
Integrated with a speaker unit and panel, the PC-1860S
Ceiling Mount Speaker is of metallic construction and ideal
for use in a voice alarm system. It features 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 push-in type input terminal block makes cable
connections easy and allows bridge wiring.

the ceiling.

4-2. Change the input impedance as needed.
The speaker's input is factory-preset to 1.7 kΩ.
When changing the input impedance, detach the
black wire connected to the matching transformer,
and reinsert it into the desired input tap referring
to the table below.

Step 5. Hook another speaker spring in another catcher.
Then, press the speaker assembly into the
mounting bracket. Force of the springs will keep
the speaker in place.
Step 2. Place the mounting bracket in the hole and secure
it with the thumb screws in the two ceiling clamps.
Note
A suspension bolt may be used instead for fixing
the mounting bracket.
Step 3. Hook one speaker spring (V-shaped spring) in the
spring catcher of the bracket.
Step 4. Make wiring.
4-1. Insert the lead-in cables (cables from the amplifier)
and lead-out cables (cables to other speakers)
into the input connector.
