M22-30K-120VB

Alarms, Buzzers, And Sirens Overview

The Omega M22-30K-120VB is a dual-tone signaling alarm designed for panel mounting with a 30 mm diameter housing. It operates on a 120 Vac supply and delivers an acoustic output of 65 dBa to 70 dBa. The unit supports both pulse and continuous sound modes, emitting a main frequency of 3500 Hz. It features NEMA 4X and IP65 ratings for protection against harsh environments. Electrical specifications include a turn-on leakage current of at least 3 mA and terminals compatible with 14 AWG (2.5 mm2) wire. The operating temperature range spans from -13°F to 140°F (-25°C to 60°C).

Alarms, Buzzers, And Sirens Feature Summary

• Dual-tone audio output capability for distinct auditory alerts.
• NEMA 4X and IP65 rated enclosure for harsh environment durability.
• Supports both pulse and continuous signaling operation modes.
• Panel mount design with 30 mm diameter form factor.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix configuration against official Omega Engineering documentation to ensure correct voltage and acoustic rating alignment. Confirm that the required mounting hardware matches the 30 mm panel cutout specification. Check terminal compatibility for 14 AWG wiring before installation. Ensure environmental conditions remain within the stated temperature limits. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a 120 Vac power source is available and a moderate acoustic level of 65-70 dBa is sufficient for the application area. The dual-tone feature aids in distinguishing alarms in noisy settings. Consider the IP65 rating if exposure to dust or water jets is expected. Verify that the 30 mm diameter fits the existing panel constraints. Evaluate whether pulse or continuous mode meets the operational signaling requirements.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Omega M22 Series of audio signal indicators. The series offers various voltage options and acoustic outputs. The M22-30K-120VB specifically addresses applications requiring 120 Vac input and robust environmental sealing. It complements other models in the lineup that may offer different frequencies or higher decibel ratings.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 120 Vac supply, 30 mm diameter, and dual-tone functionality. Verify equivalent IP65/NEMA 4X ratings for environmental compatibility. Ensure the replacement maintains the 3500 Hz frequency and similar acoustic output levels. Confirm terminal type and torque specifications align with existing wiring practices.
