It delivers a high-visibility audible alert with 101 dB(A) voice output and 110 dB(A) tone at 1 m, with 45 selectable tones across 4 output stages to suit varying alert requirements. Housed in a gray enclosure and rated UL Type 3R\/4\/4X\/13 with IP66 protection, the 855H-R30C is built to withstand dust and water exposure while mounted on equipment or panels. This model is a pure horn device (no beacon) and is specifically designed for installations where a programmable, loud alarm is needed across manufacturing floors, process lines, or safety shutoff systems; its 10–30 V DC supply supports common industrial control voltages, and the four-stage sequence enables flexible signaling patterns without external modules. Ideal for OEMs and maintenance teams seeking a configurable, durable audible warning solution, the 855H-R30C pairs with standard signaling practices on Allen-Bradley control architectures and can be integrated into safety interlock and machine alarm schemes where a robust, programmable audio response is essential.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51659284349230,"sku":null,"price":666.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e0ed0c3c-46fa-4a73-8744-713a4653e932.jpg?v=1769529016","url":"https:\/\/plgautomation.com\/products\/allen-bradley-855h-r30c-audible-warning-device","provider":"PLG Automation ","version":"1.0","type":"link"}
