Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix QOA against official Floyd Bell documentation to confirm terminal type and acoustic specifications. Ensure the application environment supports the required 40-120V AC input range. Confirm that the 2.9kHz frequency aligns with system design requirements. Check for UL or UR listing compliance if mandated by local safety regulations. Validate physical dimensions for panel cutout compatibility before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when an internally driven solution is required for AC-powered systems. The wide voltage tolerance accommodates varying line conditions. The muteable feature allows for operational flexibility in noisy environments. Consider the 97dB output level for audibility needs. Ensure the quick connect interface matches existing wiring harnesses. Verify that the panel mount style fits the enclosure design constraints.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the OC-19 series of piezo buzzers from Floyd Bell Inc. The series includes variants with different terminal styles and acoustic outputs. The OC-19-201-QOA specifically denotes the quick connect blade configuration. Other models in the family may offer screw terminals or different mounting options. All units share similar internal driver architectures.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include OC-19-201-QO and OC-19-201-QM from the same manufacturer. These alternatives share identical electrical parameters and form factors. Verify terminal compatibility when swapping between QO, QOA, and QM suffixes. Cross-reference datasheets to ensure acoustic performance meets system requirements.
