Allen-Bradley 856T-BTR3 Tone Tables Sound Module

Allen-Bradley 856T-BTR3 Tone Tables Sound Module is a 70 mm, black-housing audible signaling device designed for use with the 856T stack-light family; it mounts as the top sound module and includes a transducer to produce audible alerts. It provides 16 tone tables, each with seven tones, enabling a broad library of alert sounds that can be configured via the 856T DIP settings for varied industrial signaling needs. Power is supplied from 24 V AC/DC, and the unit delivers loud output suitable for industrial environments, rated at 105 dB(A) at 1 m. With three independent circuits, the 856T-BTR3 allows combinations and sequencing of tones by energizing different circuits, enabling diverse alarm patterns for process control, manufacturing lines, or packaging facilities when paired with 856T top-mount signal towers.
