US-09-515-Q

Overview

The US-09-515-Q is a piezoelectric chime alarm manufactured by Floyd Bell Inc, belonging to the AudioLarm II series. Designed for panel mounting, this internally driven indicator accepts DC input within a voltage range of 5 to 25 volts. It operates at a frequency of 2.9 kHz and delivers a sound pressure level of 70 dB when measured at 5 volts and a distance of 61 cm. The unit features wire leads with ports located on the top side. Its physical dimensions include a diameter of 35.81 mm and a maximum installation height of 37.59 mm. The device is rated for an operating temperature between -20°C and 65°C and holds UL and UR approval agencies.

Feature Summary

• Internally driven piezoelectric technology for reliable chime signaling
• Panel mount construction with top-positioned wire lead connections
• IP68 rating providing dust tight and waterproof protection
• UL and UR agency approvals for industrial safety compliance

Applications

• Industrial machinery status indication
• Control panel audio alerts
• Equipment fault signaling systems
• Automated manufacturing process monitoring

Procurement Notes

Verify that the specific part number matches the required voltage range and acoustic output specifications for the target application. Confirm that the IP68 rating meets environmental exposure requirements. Ensure compatibility with existing panel cutouts given the specified diameter and height constraints. Check for current UL/UR certification validity if regulatory compliance is mandatory for the end-use environment.

Selection Notes

Select this component when a robust, waterproof chime alarm is required for harsh industrial environments. The internal drive circuit simplifies integration by eliminating the need for external driver components. Consider the 70 dB output level relative to ambient noise conditions. Verify that the 5 to 25 VDC input aligns with available system power supplies. The panel mount style suits applications requiring direct enclosure installation rather than PCB mounting.

Part Context

This model belongs to the AudioLarm II series, recognized as a widely used industrial alarm line. It represents a standard piezoelectric solution for durable industrial machines. The design prioritizes reliability and environmental sealing over complex tone variations. It serves as a fundamental audio indicator within broader control systems where clear, loud chimes are necessary for operator awareness.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other AudioLarm II models only if electrical parameters and mounting dimensions match exactly.
