Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix SU2 against official Mallory Sonalert documentation to confirm the exact tone pattern and electrical characteristics. Ensure the application voltage matches the 16-28 VDC rating. Confirm that the terminal block interface is compatible with the intended wiring harness or PCB layout before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a high-intensity 95 dBA signal is required in harsh environments due to its IP66 rating. The ZA series offers a compact 30.74 mm form factor suitable for tight panel spaces. Consider the 40 mA current draw for power supply sizing. Verify that the terminal block termination method aligns with the assembly process.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the ZA series of panel-mount alarms manufactured by Mallory Sonalert Products Inc. The series is characterized by robust piezoelectric elements and standardized dimensions for easy integration into industrial enclosures. The ZA028 prefix indicates a 30.74 mm diameter housing.

Alarms, Buzzers, And Sirens Replacement Considerations

Check for direct substitutes within the ZA series with different suffixes for varied tones. Cross-reference with other Mallory Sonalert series like SCE if size constraints differ. Ensure any replacement maintains the 16-28 VDC operating range and terminal block connectivity.
