UT-09-515-W

Overview

The UT-09-515-W is a piezoelectric panel mount 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 with a sound pressure level of 70 dB at 5V measured at 61 cm. Power consumption ranges from 5 to 25 mA. It provides IP68 protection against dust and water, ensuring durability in harsh environments. The unit utilizes wire leads for termination and is designed for top port placement.

Feature Summary

• IP68 rated enclosure providing dust tight and waterproof protection for reliable operation in wet or dusty conditions
• Internally driven indicator circuit simplifies integration by eliminating the need for external driver components
• Piezoelectric technology delivers consistent acoustic performance across the specified operating temperature range

Applications

• Industrial machinery status indication
• Automated manufacturing equipment alarms
• Heavy duty vehicle warning systems

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact electrical ratings and termination style. Ensure the selected variant matches the required voltage range and mounting configuration for the target application. Cross-reference approval agency listings such as UL or UR if regulatory compliance is mandatory for the end product deployment.

Selection Notes

Select this component when high environmental resistance is required alongside standard audible alerting functions. The internal drive capability reduces board space requirements compared to externally driven alternatives. Confirm that the 70 dB output level meets the ambient noise requirements of the installation site without necessitating additional amplification stages.

Part Context

This model belongs to the AudioLarm II series, which represents a widely used line of industrial alarms known for durability. The series combines piezoelectric sounders with visual indicators in compact panel-mount housings. This specific model emphasizes environmental sealing and straightforward DC operation for robust field performance.

Replacement Considerations

Consult official substitution guides for direct replacements. Verify pinout compatibility and acoustic output levels before integrating alternative models into existing designs.
