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.
