CEILING MOUNT SPEAKER
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
CAUTION
Indicates a potentially hazardous situation which,
if mishandled, could result in death or serious
personal injury.
Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.
• 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.
• 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-1860 and PC-2360 Ceiling Mount Speakers are of all metallic construction
and ideal for use in a voice alarm system.
They feature 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.

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.
