Industrial Workstation Andon Signal Light : Designed for industrial workstations and production lines, this 4-Stack LED Andon tower with built-in buzzer and 16-ft extension cord provides clear visual and audible status signals, supporting lean manufacturing, reducing response time, and improving operational efficiency. Industrial-Grade Construction with High-Visibility LEDs : Constructed with PC lens, ABS housing, and aluminum alloy pole for long-lasting durability in industrial environments. Red/Yellow/Green/Blue LEDs each feature 6 high-brightness LEDs, wide viewing angles, and minimal light degradation, ensuring reliable visibility over time. ABB Selector Switch Control & Adjustable LEDs : Equipped with a 2-hole control box and genuine ABB industrial selector switches. Each LED layer can be independently set to steady (ON) or flashing mode, with a flash rate of 65 times per minute. Operators can flexibly indicate machine or process status while maintaining reliable manual control via ABB switches. Built-in Buzzer – Clear Audible Alerts : Integrated buzzer provides a maximum volume of 85 dB, ensuring audible alerts are clearly heard even in noisy industrial environments. Combined with visual signals, it enhances safety and response efficiency. Mean Well Industrial Power Adapter & 16-ft Extension Cord – Stable and Plug-and-Play : Powered by a genuine Mean Well AC-DC industrial adapter with a 2-pin USA plug and 16-ft extension cord for flexible installation. Input range 85–264VAC; extremely low no-load power (<0.075W). Flame-retardant 94V-0 housing and double insulation enhance electrical safety. Plug-and-play design for quick workstation or machinery installation. Suitable for indoor industrial applications such as factories, warehouses, workshops, labs, and maintenance areas. Wide Voltage Compatibility: Universal power supply accepts 85-264V AC input, making this signal tower compatible with electrical systems worldwide for flexible installation across different regions and facilities 360-Degree Visibility Design: High-intensity LED modules emit light in all directions, ensuring signals are visible from any angle in large industrial spaces, improving response time and communication efficiency The ANDONT 4-Stack LED Andon Tower Light with Buzzer and 16-ft extension cord is a robust industrial signaling solution for workstations and production lines. Its Red/Yellow/Green/Blue LED stack provides highly visible status indication, while the 85 dB buzzer ensures audible alerts even in noisy environments. Industrial-grade construction (PC lens, ABS housing, aluminum alloy pole) and ABB selector switches allow each LED layer to operate in steady or flashing mode, offering flexible and reliable machine/process status display. The included 16-ft extension cord and plug-and-play design allow easy installation on workstations or machinery. Ideal for lean manufacturing, enhancing response time, and improving operational safety and efficiency. Fully compatible with other ANDONT tower versions for a consistent industrial signaling system.
