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.
• 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
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 bracket.
Extreme force is applied to the unit and the unit could fall off,
possibly resulting in personal injuries.
Integrated with a speaker unit and panel, the PC-1869, PC-2369,
PC-2852, and PC-2869 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 (PC1869, PC-2369 and PC-2869) or 670 Ω (PC-2852).
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.
