MSE14MSU2

Alarms, Buzzers, And Sirens Overview

The MSE14MSU2 is a piezoelectric buzzer from the MSE series by Mallory Sonalert Products Inc. It features an internal driver circuit and accepts DC input within a voltage range of 7 to 14 VDC. The device operates at a current of 50 mA with a sound pressure level of 75 to 85 dBA. Its primary function is a fast speed-up alarm mode, characterized by a pulse rate ranging from 0.5 to 8 pulses per second increasing over 30 seconds. The unit utilizes through-hole PC pin termination for board mounting.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix against the manufacturer's official part numbering guide to ensure correct acoustic output and operational mode. Confirm mechanical dimensions and terminal type compatibility with the target printed circuit board layout prior to procurement. Check RoHS compliance status if required by project specifications.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a dynamic accelerating alert is required rather than a continuous or steady-tone signal. Ensure the application environment supports the specified operating temperature range. Verify that the 50 mA current draw is compatible with the available power supply capacity on the host system.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the MSE series of miniature board mount buzzers. The series offers various acoustic modes including chimes, whoops, and pulses. The MSE14MSU2 specifically provides a speed-up variation within this family, distinguished by its changing pulse rate profile compared to constant frequency alternatives.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult the Mallory Sonalert part numbering guide for exact functional equivalents. Substitutes must match the 7-14 VDC operating range, 50 mA current consumption, and 23 mm x 23 mm form factor.
