INSTALLATION MANUAL

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.

• 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

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-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.

Dimensions Weight

• 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.

Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

4-2. 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 table below.

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.

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.

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 4. Make wiring.

4-1. Insert the lead-in cables (cables from the amplifier)

and lead-out cables (cables to other speakers) into the input connector.
