Allen-Bradley 855H-BD30CD Industrial Horn Base delivers a high-visibility 112 dB signaling tone from a gray ABS-housed base, designed for surface or on-the-wall mounting with conduit openings and hole plugs for back-feed or conduit feeds. It operates from 10 to 30 V DC, draws about 25 mA, and offers 32 selectable tones for versatile signaling in industrial environments. The unit is rugged for harsh settings with IP66 and NEMA 4X protection, a operating temperature range of -25 °C and storage temperature of -40 °C, and is built to withstand 15 G shock and 3 G vibration. The horn cover and base are made of ABS plastic, and the assembly is an electric horn (not pneumatically operated).
