AD16-22SM Red LED Indicator Buzzer – 220V AC, 22mm Panel Mount

The AD16-22SM Red Indicator Buzzer is a compact panel-mounted audible and visual signaling device designed for 220V AC electrical and industrial control systems.

It combines a red LED warning indicator with an integrated buzzer, allowing operators to receive both visual and audible notification of alarms, faults, equipment status, or other control conditions.

The standard 22mm panel-mount design makes it suitable for electrical cabinets, machinery, automation panels, power distribution systems, and industrial control equipment.

Audible & Visual Warning

The AD16-22SM combines two signaling functions in a single compact panel device.

The red indicator provides a clear visual warning, while the integrated buzzer provides an audible alarm to attract the operator's attention.

This combination is particularly useful in environments where a visual indicator alone may not be noticed immediately.

22mm Panel Mount

The indicator is designed for installation in a standard 22mm control-panel opening, making it suitable for use alongside push buttons, selector switches, emergency controls, and other industrial panel components.

Its compact construction allows it to be easily integrated into new control panels or used as a replacement indicator in existing equipment.

Applications

Ideal for industrial control panels, machinery, CNC equipment, electrical cabinets, power distribution panels, automation systems, PLC panels, fault alarms, warning systems, HVAC equipment, production machinery, and equipment-status indication.

It can be used to indicate conditions such as machine faults, power status, warnings, process alarms, or equipment requiring operator attention.

Important Note

AD16-22SM products are manufactured in several voltage, sound, illumination, and construction variants. This product should therefore be identified specifically as the red 220V AC version.

Exact sound level, flashing behavior, protection rating, and continuous/intermittent buzzer operation can vary between manufacturers. Check the markings on the supplied unit when these characteristics are critical to the application.

Safety Warning

This indicator operates directly from 220V AC mains voltage.

Always disconnect power before installation, wiring, or servicing. Use correctly rated wiring and install the device in a suitable electrical enclosure or control panel.

Installation in mains-voltage systems should be performed by a qualified electrician or appropriately trained technician.
