UW-09-515-S(F)

Overview

The UW-09-515-S(F) 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 output 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 during operation and functions reliably in temperatures ranging from -20°C to 65°C. It features IP68 ingress protection against dust and water, ensuring durability in demanding environments.

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 wire leads

Applications

• Industrial equipment status indication
• Marine or outdoor control panels requiring waterproofing
• HVAC system alarm signaling

Procurement Notes

Verify that the specific suffix (F) matches the required lead configuration and housing material specifications. Confirm that the operating voltage aligns with the 5-25V DC range to ensure proper actuation. Check environmental ratings against site conditions to validate IP68 suitability. Ensure panel cutout dimensions accommodate the specified diameter and height constraints.

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 SPL for applications where moderate volume is sufficient without excessive noise pollution. Verify thermal limits if the installation area exceeds standard ambient temperatures.

Part Context

This part belongs to the Audiolarm II family of piezoelectric alarms from Floyd Bell Inc. These devices are engineered for high reliability in industrial settings. The series offers various voltage and frequency options, but this specific model emphasizes environmental sealing and broad voltage compatibility for versatile integration into control systems.

Replacement Considerations

Cross-reference physical dimensions and electrical parameters when substituting. Ensure any alternative maintains IP68 rating and compatible mounting style.
