UB-09-515-S(F)D

Overview

The UB-09-515-S(F)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 61 cm. The unit draws between 5 and 25 mA during operation and functions reliably in temperatures ranging from -20°C to 65°C. It features UL and UR approval agencies certification and meets IP68 standards for dust tightness and waterproofing. Physical dimensions include a diameter of 35.81 mm and a maximum installation height of 37.59 mm.

Feature Summary

• Internally driven piezoelectric mechanism for direct DC input
• IP68 rated enclosure providing dust tight and waterproof protection
• Panel mount construction with top-positioned port and wire lead termination

Applications

• Industrial equipment status indication
• Appliance audio signaling
• Control panel alarm systems

Procurement Notes

Verify that the specific suffix (F)D matches the required lead configuration and housing material specifications for your assembly. Confirm that the operating voltage aligns with the 5-25V DC range to ensure proper actuation. Check that the physical mounting hole dimensions accommodate the 35.81 mm diameter. Ensure environmental conditions do not exceed the specified temperature limits or compromise the IP68 seal integrity during installation.

Selection Notes

Select this component when a robust, waterproof audible indicator is required for harsh environments. The wide voltage tolerance allows flexibility in power supply design. Consider the 70 dB output level against ambient noise requirements. Verify that the internal driver circuitry suits the control logic without requiring external amplification components.

Part Context

This part belongs to the Floyd Bell Audiolarm II series, which specializes in piezoelectric chimes and alarms. The series offers various mounting styles and acoustic outputs. This specific model emphasizes environmental sealing and durability, distinguishing it from standard indoor indicators through its IP68 rating and UL/UR certifications for safety compliance in diverse applications.

Replacement Considerations

Cross-reference with other Floyd Bell models in the same series for dimensional compatibility. Ensure substitute parts maintain equivalent IP ratings and electrical characteristics if environmental sealing is critical.
