Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix SU2B corresponds to the required fast speed-up tone and terminal configuration. Confirm that the 48-120V AC input range matches the system supply voltage. Ensure the panel cutout dimensions accommodate the 42.85mm diameter. Check for updated UL/cUL certification status before final integration.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a fast speed-up tone is required for AC-powered industrial applications. The internal driver simplifies wiring by eliminating external components. Consider the 95dB output level for noise environment suitability. Verify that the panel mount style fits the enclosure design constraints.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Mallory Sonalert SCE series of piezoelectric buzzers. The series offers various tones and voltage ratings for industrial audio indication. The SCE120XA3SU2B specifically targets higher voltage AC inputs with a distinct fast speed-up pattern. It provides a standardized solution for panel-mounted alerting needs.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference other SCE series part numbers with matching 48-120V AC ratings and 2.9kHz frequency. Verify that alternative models support the same fast speed-up tone pattern. Ensure replacement units maintain identical panel mounting dimensions and terminal block configurations.
