US-05-515-P

Overview

The US-05-515-P 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 a DC input voltage range of 5 to 25 volts. It operates at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5 volts and 61 cm distance. The unit draws between 5 and 25 mA of power. Physical dimensions include a diameter of 35.81 mm and a maximum installation height of 37.59 mm. It features wire leads for termination and an IP68 rating for dust tightness and waterproofing. Operating temperatures range from -20°C to 65°C, and it holds UL and UR approvals.

Feature Summary

• Internally driven piezoelectric chime mechanism
• IP68 rated for dust tightness and waterproofing
• UL and UR agency approved
• Panel mount design with top port location

Applications

• Industrial equipment status indication
• Control panel alarm signaling
• Appliance audio feedback systems

Procurement Notes

Verify the specific manufacturer part number against official Floyd Bell documentation to ensure compatibility with system voltage requirements. Confirm that the internal drive circuit matches the control logic interface. Check for updated certification marks such as UL or UR if required for final product compliance. Ensure environmental ratings meet the operational temperature and ingress protection needs of the installation site.

Selection Notes

Select this component when a self-contained, internally driven audible signal is required without external driver circuits. The wide voltage range allows flexibility in power supply design. Consider the physical size constraints due to the 35.81 mm diameter. Verify that the 70 dB SPL is sufficient for the ambient noise environment. The IP68 rating makes it suitable for harsh or wet conditions where standard indicators would fail.

Part Context

This part belongs to the Audiolarm II series of piezoelectric chimes from Floyd Bell Inc. These devices are designed for reliable audio signaling in various industrial and commercial applications. The series offers different voltage and frequency options to suit specific system requirements while maintaining consistent build quality and certification standards.

Replacement Considerations

Consult official Floyd Bell documentation for direct cross-references. Verify pinout, voltage, and SPL compatibility before substituting with other brands.
