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.
