MB-09-530-W(U)

Alarms, Buzzers, And Sirens Overview

The MB-09-530-W(U) is a panel mount chime alarm from the Audiolarm II series manufactured by Floyd Bell Inc. It utilizes piezo technology for sound generation and features an internally driven indicator circuit. The device operates on a DC voltage range of 5 to 25 volts with a power consumption current between 5 and 25 mA. It produces a frequency of 2.9 kHz and achieves a sound pressure level of 70 dB at 5 volts measured at a distance of 61 cm. The unit is designed for top port wiring and offers IP68 protection against dust and water ingress, functioning within a temperature range of -20°C to 65°C.

Alarms, Buzzers, And Sirens Feature Summary

• IP68 rated enclosure providing dust tight and waterproof sealing
• Panel mount construction with top wire lead connections

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indication
• Control panel alarm signaling
• Enclosure-mounted warning systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix (U) against official documentation to confirm any distinct material or termination variations compared to standard variants. Ensure the required operating voltage aligns with the 5 to 25 VDC specification. Confirm that the 70 dB SPL meets the acoustic requirements for the intended installation environment. Check UL/UR approval agency listings if regulatory compliance is mandatory for the final assembly.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a rugged, waterproof audible indicator is required for panel mounting. The wide voltage tolerance allows compatibility with various DC power supplies. The high ingress protection rating makes it suitable for harsh environments where exposure to moisture or dust is likely. Consider the physical dimensions and top-entry wiring configuration during mechanical design integration.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Audiolarm II series of piezo chimes. It shares the same form factor and core acoustic characteristics as other models in the line, such as the CH-V09-525-W(F). The primary differentiators are typically found in the ordering suffixes which may denote specific packaging or minor manufacturing revisions rather than functional changes.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other Audiolarm II models like CH-V09-525-W(F) for dimensional and electrical compatibility. Verify that substitute parts maintain the IP68 rating and UL certification if required. Ensure the replacement supports the same 5-25 VDC input range and provides equivalent acoustic output.
