Procurement Notes
Verify the specific suffix against official Mallory Sonalert documentation to confirm electrical characteristics and compliance status. Confirm availability with authorized distributors as supply levels fluctuate. Ensure the component meets the required environmental specifications for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this component when a self-contained, high-intensity audible alert is required for panel-mounted applications. The internal drive circuitry simplifies design by eliminating external oscillator requirements. Verify that the 85 dBA output level satisfies regulatory noise constraints for the specific installation location.
Part Context
This part belongs to the Mallory Sonalert SBT series of piezoelectric buzzers. The series is recognized for providing reliable audio signaling solutions across industrial, medical, and transportation sectors. The manufacturer maintains a long-standing reputation for producing standardized alarm components with consistent performance metrics.
Replacement Considerations
Consult official Mallory Sonalert cross-reference lists for verified substitutes. Generic replacements may not match the internal drive circuitry or acoustic profile. Ensure any alternative part supports the same voltage range and mounting configuration.
