MB-V09-530-S(U)D

Alarms, Buzzers, And Sirens Overview

The MB-V09-530-S(U)D is a piezoelectric chime alarm manufactured by Floyd Bell Inc, belonging to the Audiolarm II series. Designed for panel mounting, this internally driven indicator utilizes wire leads for connection and operates within a DC voltage range of 5 to 25 volts. It generates an acoustic signal at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5V and 61cm. The unit draws between 5 and 25 mA of power and features IP68 ingress protection, ensuring it is dust-tight and waterproof. It functions reliably across an operating temperature range of -20°C to 65°C and holds UL and UR approval agency certifications.

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the specific suffix (U)(D) matches the required environmental sealing and terminal configuration for your application. Confirm that the 5-25V DC operating range aligns with your system's power supply. Ensure the panel cutout dimensions accommodate the 35.81mm diameter and 37.59mm maximum height. Check for current UL/UR listing requirements in your target market before finalizing the order.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when both audible signaling and high environmental protection are required. The IP68 rating distinguishes it from standard indoor chimes, making it suitable for washdown or outdoor use. The wide voltage tolerance allows compatibility with various DC bus voltages without external regulation. Consider the 70dB SPL output against ambient noise levels to ensure adequate audibility.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Audiolarm II family of piezoelectric chimes from Floyd Bell Inc. These components are designed as robust, self-contained acoustic indicators. The series emphasizes durability and environmental resistance, catering to industries where standard electronic components might fail due to moisture or particulate ingress. It serves as a direct replacement for older mechanical or lower-rated piezo units.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference physical dimensions and electrical parameters when substituting. Verify that any alternative part meets the same IP68 rating and UL/UR certification standards. Ensure the replacement supports the 5-25V DC input range and provides comparable acoustic output at the specified distance.
