M22-30V-12VB

Alarms, Buzzers, And Sirens Overview

The Omega M22-30V-12VB is a dual-tone signaling alarm from the M22 series, designed for panel mounting with a 30 mm diameter. It operates on a supply voltage range of 12 Vac/Vdc to 24 Vac/Vdc and draws 20 mA at 24 V. The unit produces an acoustic output between 80 dBa and 85 dBa at a frequency of 3.5 kHz. It supports both pulse and continuous operation modes and features internally driven magnetic technology with screw terminals.

Alarms, Buzzers, And Sirens Feature Summary

• Dual-tone audio signaling capability
• Selectable pulse or continuous operation modes
• Internally driven magnetic driver mechanism

Alarms, Buzzers, And Sirens Applications

• Industrial machine status indication
• Harsh environment safety alarms
• Control panel auditory alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific voltage rating (12-24 VAC/DC) against your system power supply before procurement. Confirm that the required sound pressure level (80-85 dBA) meets site noise regulations. Ensure the 30 mm mounting hole dimension matches existing panel cutouts. Check for necessary IP65/NEMA 4X environmental sealing requirements for the installation location.

Alarms, Buzzers, And Sirens Selection Notes

Select this model if a dual-tone signal is required rather than a single tone. Choose this part when the operating voltage is strictly within the 12-24 VAC/DC range. Consider this unit for applications requiring NEMA 4X or IP65 ingress protection ratings. Opt for this component when a 30 mm panel mount footprint is specified in the design.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Omega M22 series of audio signal indicators. The series includes variants with different voltages, tones, and colors. The M22-30V-12VB specifically denotes the 30 mm size, 12-24 VAC/DC voltage class, and dual-tone configuration within the broader product line.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other M22 series units with identical 30 mm mounting dimensions and compatible voltage ranges. Verify that replacement parts maintain the same IP65/NEMA 4X rating if environmental sealing is critical. Ensure the substitute also offers dual-tone functionality if that feature is required.
