MSE14LSU2S

Alarms, Buzzers, And Sirens Overview

The MSE14LSU2S is a piezoelectric buzzer from the Mallory Sonalert MSE series, designed for panel or board mounting. It operates on a DC input voltage range of 7 to 14 VDC with a current consumption of 50 mA. The device features an internal driver circuit and produces a fast speed-up tone at a frequency of 3.9 kHz. Its acoustic output reaches 85-95 dBA, measured at a distance of 10 cm. The unit utilizes solder pin termination for through-hole installation and maintains a compact form factor of 23 mm x 23 mm x 13.5 mm.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates an internal driver circuit for direct connection to power sources without external oscillators.
• Generates a fast speed-up audio alert pattern that increases in pitch over time.
• Constructed with sealed piezoelectric technology suitable for washable environments.
• Features top-mounted ports for directional sound projection.

Alarms, Buzzers, And Sirens Applications

• Medical equipment alarm systems
• Industrial control panels
• Security and safety signaling devices

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'SU2S' against official Mallory Sonalert documentation to confirm the fast speed-up waveform configuration. Ensure the operating voltage aligns with the 7-14 VDC specification. Confirm RoHS3 compliance requirements if applicable to your assembly process. Cross-reference the datasheet for exact mechanical tolerances before finalizing PCB or panel layouts.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a rising pitch alert is required rather than a continuous tone. The 50 mA current draw necessitates appropriate power supply sizing. The 23x23mm footprint allows for standard mounting holes. Consider the 85-95 dBA output level relative to ambient noise conditions. The sealed design supports cleaning procedures in regulated environments.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSE series of piezoelectric buzzers manufactured by Mallory Sonalert Products Inc. The series offers various waveforms including sirens, pulses, and whoops within a standardized 23x23mm package. These components are widely used in applications requiring high-intensity audible alerts with integrated driving electronics.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 23x23mm dimensions, 7-14VDC rating, and fast speed-up waveform. Verify that alternative parts maintain the same 50 mA current draw and 85+ dBA output level. Check for identical solder pin configurations and washable sealing ratings.
