Allen-Bradley 855T-B24TA1 Dual Tone Tower Light

Allen-Bradley 855T-B24TA1 is a transducer-style dual-tone sound module for 70 mm 855T control tower stack lights, featuring a black housing and a 24 V AC/DC supply. It supports up to 15 distinct tone combinations and offers adjustable audible signaling with volume from 85 to 103 dB at 1 meter, plus programmable tone frequency and tone speed to match different operating environments. The module carries UL Type 12 and IP54 ratings, providing protection suitable for industrial settings, and is designed to pair with light modules within the 855T family to deliver integrated light-and-sound alerts. Typical applications include signaling machine status or alarm conditions on production lines, manufacturing cells, and packaging or process-control equipment where both visual and audible cues are needed.
