Procurement Notes

Verify the specific suffix against official Mallory Sonalert documentation to confirm exact acoustic and electrical characteristics. Ensure compatibility with the target PCB layout regarding the 44.45 mm diameter footprint and 15 mm height clearance. Confirm that the 630 mA current draw aligns with the system power supply capabilities before integration.

Selection Notes

Select this component when a dedicated cardiac alert tone is required for medical or safety devices. The high current rating necessitates appropriate driver circuitry on the PCB. Verify that the 9-12 VDC operating range matches the available system voltage rails. Consider the 15 mm profile height during mechanical enclosure design to ensure adequate space for the transducer assembly.
