INSTALLATION MANUAL

CEILING MOUNT SPEAKERS

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.

• 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.

1. SAFETY PRECAUTIONS

• 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.

Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

CAUTION

• 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.

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 (PC- 1869, 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.

Never connect to the 330 Ω tap in a 100V line system, as excessive input power is applied to the speaker, possibly resulting in damage.

Step 4. Push the panel surface into the mounting hole.

4. 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.
