Thank you for purchasing TOA’s Ceiling Mount Speaker.
Please carefully follow the instructions in this manual to ensure the long,
trouble-free use of your equipment.
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 that, 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 bracket. Extreme force is applied to the unit and the unit could fall off, possibly resulting in personal injuries.
CAUTION
Indicates a potentially hazardous situation that, 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.
GENERAL DESCRIPTION
Integrated with a speaker unit and panel, the PC-1860 and Ceiling Mount
Speakers are of all metallic construction and ideal for use in a voice alarm
system.
They feature a spring clamp 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.

INSTALLATION
Step 1. Using the supplied paper pattern as a guide, open a mounting hole
of the dimension specified below in the ceiling.
Step 2. Hook the speaker mounting spring into the mounting hole in the
ceiling.
Step 3. Make wiring.
3-1. Insert the lead-in cables (cables from the amplifier) and lead-out cables
(cables to other speakers) into the input connector.
[When making a bridge connection]
3-2. 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 tables below.
| Impedance | 1.7 kΩ | 3.3k Ω | 6.7kΩ | 13 kΩ |
|---|---|---|---|---|
| 100 V line | 6W | 3W | 1.5W | 0.8W |
| 70 V line | 3W | 1.5W | 0.8W | 0.4W |
Step 4. Push the panel surface into the mounting hole.
