US-09-515-S

Overview

The US-09-515-S is a panel mount chime alarm manufactured by Floyd Bell Inc, belonging to the AudioLarm II series. It utilizes piezo technology for sound generation and features an internally driven indicator circuit. The device operates on DC input with a voltage range of 5 to 25 volts. It produces 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. The unit has IP68 ingress protection, rated dust tight and waterproof. Operating temperature spans -20°C to 65°C. Physical dimensions include a diameter of 35.81 mm and a maximum installation height of 37.59 mm. Termination is provided via wire leads positioned at the top.

Feature Summary

• IP68 rated enclosure providing dust tight and waterproof protection for harsh environments
• Internally driven piezo driver circuit simplifies integration into control panels
• Top-mounted wire lead termination facilitates straightforward electrical connections

Applications

• Industrial machinery status indication
• Panel mounted safety alarms
• Equipment chime signaling in manufacturing settings

Procurement Notes

Verify the specific suffix against official Floyd Bell documentation to confirm exact termination style and acoustic specifications. Ensure the operating voltage aligns with the 5 to 25 VDC range specified for this model. Confirm environmental requirements match the IP68 rating and temperature limits before deployment. Cross-reference the part number with current manufacturer catalogs to ensure availability and active status.

Selection Notes

Select this component when a robust, waterproof piezo chime is required for panel mounting. The internal drive capability reduces external component count compared to externally driven alternatives. Consider the 70 dB output level relative to ambient noise conditions. Verify that the physical dimensions fit the available panel cutout space and that the wire lead termination suits the wiring harness design.

Part Context

This part belongs to the AudioLarm II series, described as a widely used industrial alarm line. It competes within the category of durable industrial machine audio devices. The product is distinct from the Turbo or Twin Turbo series which offer higher output or combined lighting features. It serves as a standard chime solution rather than a high-intensity siren.
