Allen-Bradley 855T-B24TC5 Amber Orange Stack Light Sound Unit combines a visual amber/orange indicator with a built-in audible signal for the 855T Control Tower Stack Light system. Designed to mount on a Control Tower base, it supplements status indication with an audible alert to draw operator attention in noisy factory environments. As part of the 855T family, it is intended to be used with compatible stack-light bases and can be paired with other light modules to form a signaling tower. Typical applications include manufacturing lines and process controls where quick, unambiguous signaling of status or alarms is required.
