Allen-Bradley 855P-B10LE22 is a panel-mount audible alarm sounder with a black housing designed for 120 VAC signaling in industrial control panels. It features a 65 mm diameter enclosure with a 22.5 mm mounting hole and delivers audible output in the 85–103 dB range at 1 m, making it suitable for audible signaling in noisy environments and standard machine-safety alarms. At 120 VAC, the nominal current draw is about 40 mA, and this model is part of the 855P family of compact signaling devices used for standalone sound indication within control panels.
