Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct voltage and acoustic specifications. Confirm that the external driver circuit can supply the required 70 mA current at the specified peak-to-peak voltage. Ensure mechanical compatibility with the target printed circuit board layout regarding pin spacing and mounting requirements.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an externally driven solution is preferred over internally driven piezoelectric alternatives. It is suitable for designs requiring a specific magnetic transducer frequency response. Consider the 85 dBA output level relative to the ambient noise environment of the final assembly. Verify that the 4.5 to 5.5 V input range aligns with the system's available signal levels.
