KEY FEATURES
Dual Audio-Visual Warning
The unit combines two warning functions in one compact device:
- Flashing LED light for visual notification
- Built-in piezo buzzer for audible notification
This makes it useful for machine alarms, water-level warnings, fault indication and equipment-status alerts.
High-Visibility Flashing LED
The bright LED provides a clear flashing visual signal that can be easily noticed from the machine operator’s position.
It is particularly useful in industrial environments where machinery, lighting and background activity can make conventional indicator lamps difficult to notice.
Built-in Piezo Buzzer
The integrated buzzer provides an audible alert to draw attention to the associated machine or control-panel condition.
- Low water level
- Machine fault
- Pump status
- Boiler alarm
- Emergency warning
- Equipment status
220V AC Operation
Designed for compatible 220V AC control-panel applications.
Always verify the actual voltage rating printed on the product before electrical connection.
Standard 22mm Panel Mount
The AD16-22SM is designed for a standard 22mm panel cutout, making it suitable for many industrial control panels and electrical enclosures.
Durable Housing
The indicator uses a durable, flame-resistant style housing suitable for demanding control-panel environments.
Screw-Terminal Connections
The rear connection arrangement allows convenient wiring in compatible electrical panels and control systems.

For example, it can provide a visual and audible warning when a water-level controller detects a low-water condition, provided the controller’s output circuit is compatible.
INDUSTRIAL CONTROL PANELS
Suitable for compatible:
- Electrical control panels
- Machine-control cabinets
- Automation panels
- Distribution boards
- Pump control panels
- Motor control systems
- Industrial machinery
- Process-control equipment
MOUNTING COMPATIBILITY
22mm Panel Cutout
The indicator is designed for standard 22mm panel mounting.
It is suitable for control panels where the existing mounting hole matches the AD16-22SM/AD16 series dimensions.
Panel Thickness
Always verify the available panel thickness and threaded-barrel length before installation.
COMMON WARNING APPLICATIONS
Low-Water Alarm
Provides an audible and flashing visual warning when a connected water-level controller detects a low-water condition.
Boiler Alarm
Can indicate a boiler-related warning condition in compatible steam equipment.
Pump Warning
Can alert the operator when a pump-control system detects a fault or abnormal condition.
Machine Fault
Can provide an audio-visual indication when connected to a compatible machine fault circuit.
Power / Status Indication
Can be used as a visual status indicator for a compatible electrical circuit.
Emergency Warning
Can be integrated into suitable control systems requiring a flashing light and audible alarm.
HOW IT WORKS
The indicator operates as part of the machine’s electrical control circuit.
When the connected circuit provides the appropriate 220V AC supply, the device activates its warning functions according to its specific configuration.
The operator can then receive:
Electrical Signal → LED Flashing + Buzzer Alert → Operator Warning
The actual triggering condition depends entirely on the control circuit in which the indicator is installed.
