CEILING MOUNT SPEAKER
PC-1869S
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.
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-1869S
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.
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.

5. INSTALLATION
Step 1. Make a 150 ±3 mm (5.91 ±0.12 in) diameter hole in
the ceiling. Marking-off pins provided on the
mounting bracket will help draw the circle of its
diameter on the ceiling.

Note
Raise both pins, and draw a circle with the
sharp pin as its center and another pin as a
scriber.

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 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 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.
