Allen-Bradley 855H-BA10CD Industrial Audible Alarm Horn

Allen-Bradley 855H-BA10CD Industrial Horn is a rugged 115V AC audible alarm designed for demanding industrial environments. It delivers 112 dB at 1 meter with 32 selectable tones and draws 20 mA at 115V AC (50/60 Hz). The horn is housed in a gray ABS cover with a plastic enclosure and mounts on a standard base suitable for surface or wall installation with conduit openings and hole plugs. Built for tough conditions, it carries NEMA 4X and IP66 protection, along with a vibration rating of 3 G peak and a shock rating of 15 G peak, and operates in temperatures down to -25°C with storage down to -40°C. This variant is part of Rockwell Automation’s 855H signaling family and is listed as discontinued by Rockwell as of March 31, 2022, reflecting its status as a legacy signaling option. The 855H-BA10CD is designed for standalone audible signaling and can be integrated into broader plant alarm systems where a high-decibel tone is required to warn personnel on machinery, on production lines, or in other industrial spaces.
