Designed to minimize installation and adjustment time, the Clarity SX Series paging horns provide several unique features. The ball joint (Omni-Lock System) mounting arrangement allows the horn to be positioned at any angle required. Pop-on mounting of the horn to the base allows easy installation. SX paging horns are weather resistant for both outdoor and indoor paging applications. Fading and streaking due to sunlight and rust are minimized by the use of ultra-violet inhibitors and stainless-steel hardware. The shatter resistant universal base mounts to eight of the most popular electrical boxes. Included with the horn is a clamp that allows mounting directly to metal beams. A built-in diffuser provides better dispersion of the higher frequencies. A rotary selector switch allows adjustment of the audio level in 3 dB adjustments. The paging horns are available in beige, grey and white.
