Integrated with a speaker unit and panel, the PC-1869S Ceiling Mount Speaker is of all metallic construction and ideal for use in a voice alarm system. It feature V-shaped 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.
