MB-V09-301-S(U)

Alarms, Buzzers, And Sirens Overview

The MB-V09-301-S(U) is a panel mount chime alarm manufactured by Floyd Bell Inc, belonging to the Audiolarm II series. 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 rated frequency of 2.9 kHz. It produces a sound pressure level of 70 dB at 5V measured at a distance of 61 cm. Power consumption ranges from 5 to 25 mA depending on the input voltage. The unit is designed for top port mounting and offers IP68 protection against dust and water ingress. Operating temperatures span from -20°C to 65°C. Physical dimensions include a diameter of 1.410 inches (35.81 mm) and a maximum installation height of 1.480 inches (37.59 mm).

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the specific suffix (U) matches the required configuration for the Audiolarm II series, as manufacturer documentation may define specific lead times or packaging variations for this designation. Confirm that the wire leads termination style aligns with the assembly requirements. Ensure the UL and UR approval agency certifications are valid for the intended regional application standards before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a robust, waterproof chime is required for harsh environments due to its IP68 rating. The wide voltage range allows flexibility in system design without needing external regulation for standard low-voltage DC supplies. Verify that the 70 dB SPL meets the ambient noise requirements of the installation site. Consider the physical dimensions to ensure adequate clearance for the 1.480-inch height during panel integration.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Floyd Bell Audiolarm II series, which specializes in piezo-based audible signaling devices. The series is characterized by high reliability and resistance to environmental factors. The MB prefix typically denotes a specific form factor within the lineup, distinct from other series like the CH or XC lines. This model represents a standard panel-mount solution for general-purpose industrial and commercial signaling needs.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official Floyd Bell cross-reference documents for verified substitutes. Generic replacements may not match the IP68 sealing or specific 2.9 kHz frequency response. Ensure any alternative maintains the same voltage range and SPL output characteristics.
