Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'Q' against the manufacturer's datasheet to confirm compliance requirements and terminal specifications. Ensure the PCB footprint matches the through-hole lead spacing. Confirm that the external drive circuit can supply the required 55mA current at the target operating voltage within the 9-15V range.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an externally driven solution is preferred over internal oscillator types. It is suitable for designs requiring a specific 2kHz tone generated by the host microcontroller or driver IC. Consider the 85dB SPL level for audibility in moderate noise environments.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the PB series of magnetic buzzers from Mallory Sonalert. Unlike piezoelectric models, magnetic buzzers typically offer higher sound pressure levels and are driven by an external square wave signal rather than containing an internal oscillator.
