2. GENERAL DESCRIPTION

Integrated with a speaker unit and panel, the PC-1860 and PC-2360 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.
