BRP3922L-12-CT3

Overview

The Intervox BRP3922L-12-CT3 is a piezo audio buzzer designed for alarm and indicator applications. It operates at a rated voltage of 12 VDC with an operating range of 6 to 15 VDC. The device draws 95 mA at rated voltage and produces a sound pressure level of 107 dB at one meter. Its acoustic frequency is specified as 2800 Hz, falling within the broader 2300 Hz to 3300 Hz range. The unit features flange mounting with wire leads and measures 1.520 inches in diameter by 0.866 inches in height.

Feature Summary

• Internally driven piezo construction for direct connection
• Flange mount design with integrated wire leads
• High output sound pressure level for clear alerting

Applications

• Industrial alarm systems
• Machine status indicators
• Control panel audio feedback

Procurement Notes

Verify that the 12 VDC rated voltage matches your system power supply. Confirm the 95 mA current draw does not exceed driver capabilities. Ensure mechanical dimensions fit the enclosure space. Check RoHS3 compliance requirements for your project specifications.

Selection Notes

Choose this component when a high-decibel internal drive buzzer is required. The 12 VDC rating suits standard low-voltage control circuits. Consider the flange mount style for secure installation. Verify the 2800 Hz tone meets auditory detection needs.

Part Context

This part belongs to the BRP3922L series of piezo buzzers from Intervox. Similar models include variants with different voltage ratings such as 24 VDC options. The series shares common physical dimensions and mounting styles across voltage configurations.

Replacement Considerations

Direct substitutes may include other BRP3922L series parts with adjusted voltage ratings. Verify electrical parameters match before substitution. Physical compatibility remains consistent within the series.
