US-19-230-S

Overview

The US-19-230-S is a piezoelectric panel mount chime alarm manufactured by Floyd Bell Inc, belonging to the AudioLarm II series. 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 measured at 5V and 61 cm. Power consumption ranges from 5 to 25 mA depending on the applied voltage. It offers IP68 protection against dust and water ingress, ensuring durability in harsh environments. The unit utilizes wire leads for termination and is designed for top port mounting.

Feature Summary

• Piezoelectric technology provides reliable acoustic signaling without external drivers
• IP68 rated enclosure ensures complete protection against dust and waterproofing
• Internally driven indicator circuit simplifies integration into control panels
• Top-mounted port design facilitates direct airflow and sound projection

Applications

• Industrial machinery status indication
• Panel mount alarm systems requiring environmental sealing
• Automotive equipment monitoring
• Heavy-duty appliance safety alerts

Procurement Notes

Verify the specific suffix configuration against official Floyd Bell documentation to ensure compatibility with required voltage and acoustic specifications. Confirm that the wire lead termination style matches existing harness designs. Cross-reference the IP68 rating requirements with operational environment standards to validate suitability for wet or dusty conditions before finalizing procurement orders.

Selection Notes

Select this component when high environmental resistance is critical due to its sealed construction. The internal drive capability reduces bill of materials complexity by eliminating external driver components. Ensure the operating voltage falls within the specified 5 to 25 VDC range to maintain optimal performance and prevent damage to the piezoelectric element during continuous operation.

Part Context

This model is part of the AudioLarm II family, recognized as a widely used industrial alarm series. It represents a standard solution for durable audible signaling where reliability and environmental sealing are prioritized over extreme volume output. The design focuses on robustness and ease of installation for permanent panel mounting applications.

Replacement Considerations

Consult official Floyd Bell substitution guides for verified equivalents. Generic replacements may lack the specific IP68 sealing or internal drive characteristics required for proper system integration.
