Allen-Bradley 855T-B24BC4 Beacon Strobe Sounder

The Allen-Bradley 855T-B24BC4 Beacon Strobe Sounder is a 24 V AC/DC signaling module in the 855T Control Tower Stack Light family that combines an amber beacon, a built-in strobe, and an audible sounder in a single compact unit. Designed for industrial signaling on machines and control panels, it delivers both visual and audible cues to indicate alarms, status changes, or process conditions in a shared signaling stack. The B24BC4 designation indicates 24-volt operation and amber beacon color with incandescent illumination, making it suitable for warning or caution signals within multi-light configurations. As part of the 855T family, this module integrates with standard stack-light setups to form cohesive signaling towers and is intended for environments where quick, at-a-glance status cues are essential for operator response and safety.
