Alarms, Buzzers, And Sirens Procurement Notes

Verify that the specific suffix (F) matches the required lead configuration and housing material specifications in the official datasheet. Confirm UL and UR approval agency listings are current for the target market. Ensure the operating voltage aligns with the 5 to 25 VDC range to maintain the specified 70 dB SPL output. Check for any updated environmental compliance certifications prior to final procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when high ingress protection is critical due to the IP68 rating. The wide voltage tolerance allows flexibility in power supply design. Consider the physical size constraints as the diameter is approximately 35.81 mm. Verify that the top-mounted wire leads suit the enclosure design compared to side or bottom exit options available in other series models.

Alarms, Buzzers, And Sirens Part Context

This model is part of the Audiolarm II product line from Floyd Bell Inc. It shares the standard form factor and piezo acoustic mechanism found across similar panel mount chimes in the series. The designation indicates specific terminal and housing variations distinct from non-suffixed or differently suffixed variants within the same manufacturer catalog.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with MB-09-516-Q(M) for dimensional compatibility if substituting within the same manufacturer's lineup. Verify electrical parameters match before replacing units in existing assemblies.
