US-09-515-W

Overview

The US-09-515-W is a panel mount piezoelectric chime alarm from the AudioLarm II series by Floyd Bell Inc. It features an internally driven indicator circuit and accepts DC input within a voltage range of 5 to 25 volts. The device operates at a frequency of 2.9 kHz, producing a sound pressure level of 70 dB at 5 volts measured at a distance of 61 cm. Power consumption ranges between 5 and 25 mA across the specified voltage spectrum. The unit utilizes wire leads for termination and includes top-mounted ports. It is rated IP68 for dust tightness and waterproofing, with UL and UR approval agencies. Operating temperatures span from -20°C to 65°C.

Feature Summary

• IP68 rated enclosure providing dust tight and waterproof protection for harsh environments
• Internally driven indicator circuit simplifies integration without external drivers
• Piezoelectric technology ensures reliable chime output with low power consumption
• Top ported design facilitates direct wiring access for panel mounting applications

Applications

• Industrial machinery status indication
• Panel mounted safety alarms
• Equipment fault signaling in control cabinets
• Waterproof environmental monitoring systems

Procurement Notes

Verify that the specific part number matches the required voltage range and acoustic specifications for your application. Confirm that the IP68 rating meets the environmental exposure requirements of the installation site. Ensure that the wire lead termination style is compatible with the existing wiring harness or connection points. Check for any specific UL or UR listing requirements mandated by local electrical codes or facility standards before finalizing procurement.

Selection Notes

Select this component when a durable, waterproof audible indicator is required for panel mounting. The internal drive capability reduces system complexity compared to externally driven buzzers. Consider the 70 dB SPL output against ambient noise levels to ensure audibility. The wide operating temperature range supports use in both cold storage and heated industrial settings. Verify that the physical dimensions fit the available panel space and mounting hole constraints.

Part Context

This model belongs to the AudioLarm II series, recognized as a widely used industrial alarm line. It represents a standard solution for basic chime and alarm functions where reliability and environmental sealing are prioritized over high-volume sound projection. The series offers various configurations, but this specific variant focuses on robust construction with integrated driving electronics for straightforward deployment in automated systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, match the voltage range, frequency, and SPL characteristics closely. Ensure replacement units maintain equivalent IP ratings and approval agency listings to comply with existing safety certifications.
