UC-09-515-W

Overview

The UC-09-515-W 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 features a top-mounted port. It operates on a DC voltage range of 5 to 25 volts with a power consumption of 5 to 25 mA. The device 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 distance. Constructed to withstand harsh environments, it offers IP68 protection against dust and water ingress. The unit functions reliably within an operating temperature range of -20°C to 65°C and holds UL and UR approval agency certifications.

Feature Summary

• Internally driven piezoelectric mechanism for direct DC operation
• IP68 rated enclosure providing dust tight and waterproof protection
• Panel mount design with top-mounted acoustic port
• UL and UR approved for safety compliance

Applications

• Industrial equipment status indication
• Environmental monitoring systems requiring weather resistance
• Control panels in outdoor or wet locations
• Safety alarm circuits in hazardous areas

Procurement Notes

Verify that the specific part number matches the required voltage and frequency specifications for your application. Confirm that the panel cutout dimensions accommodate the 35.81 mm diameter housing. Ensure the installation environment remains within the specified -20°C to 65°C operating temperature range. Check that the wire lead termination method aligns with your system's wiring requirements. Validate that UL/UR certification meets your regional regulatory standards before finalizing procurement.

Selection Notes

Select this component when a robust, weather-resistant audible indicator is required for panel mounting. The IP68 rating makes it suitable for applications exposed to moisture or dust. Choose this model if the system operates within the 5 to 25 VDC range and requires a 2.9 kHz tone. Consider the 70 dB SPL output for environments where moderate volume is sufficient. Verify that the internal driver circuit simplifies integration compared to externally driven alternatives.

Part Context

This component is part of the Audiolarm II series from Floyd Bell Inc, which specializes in piezoelectric signaling devices. The series includes various models tailored for different voltage and acoustic requirements. The UC-09-515-W specifically addresses needs for durable, panel-mount indicators in industrial settings. Its design emphasizes reliability and environmental sealing, distinguishing it from standard indoor alarms.

Replacement Considerations

Cross-reference with other Audiolarm II models for similar form factors. Verify compatibility regarding voltage range, frequency, and SPL before substituting. Ensure any replacement maintains the IP68 rating and UL/UR approvals if required by the original design specifications.
