Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific acoustic tone configuration against project requirements before ordering. Confirm that the 20-28 VDC operating range aligns with the target system power supply. Ensure the through-hole footprint matches the printed circuit board layout. Check for any regional compliance certifications required for the intended deployment environment.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, internally driven buzzer is needed for high-volume assembly. The 23x23mm form factor suits space-constrained enclosures. Consider the 50 mA current draw for power budget calculations. Verify that the 85 dB SPL meets audibility standards for the application environment.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSE series of miniature board mount buzzers from Mallory Sonalert. The series offers various acoustic profiles including chimes and ringtones. The MSE28LPS1 specifically provides a standard continuous tone suitable for general alarm applications.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other MSE28 variants such as MSE28MCM3 or MSE28LTT3 if different acoustic tones are acceptable. Verify pin compatibility and mounting dimensions before substituting.
