Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix or variant against official East Electronics documentation to ensure compatibility with required voltage and acoustic specifications. Confirm that the wire lead configuration matches the target assembly design. Cross-reference datasheet parameters such as SPL and operating temperature against application requirements before finalizing procurement decisions.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a simple, passive piezoelectric solution is required for audible alerts. Ensure the driving circuit can provide the necessary voltage within the 3V-24V range. Consider the 32mm form factor for spatial constraints in the enclosure design. Verify that the 10mA current draw aligns with the power budget of the host system.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the East Electronics line of alarms, buzzers, and sirens. It is categorized as a piezoelectric buzzer intended for general-purpose signaling. The product is distinct from active buzzers or electromagnetic types due to its specific construction and lack of integrated driver electronics.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Generic replacements may differ in SPL, frequency, or physical dimensions. Do not assume interchangeability based solely on voltage ratings without verifying acoustic and mechanical specifications.
