UB-09-515-Q(F)D

Overview

The UB-09-515-Q(F)D is a piezoelectric chime alarm manufactured 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 measured at 5 volts and 61 cm distance. Power consumption ranges from 5 to 25 mA across the operating voltage spectrum. Designed for panel mounting, it includes wire leads for connection and offers IP68 protection against dust and water ingress. The unit functions reliably in temperatures between -20°C and 65°C.

Feature Summary

• Internally driven piezoelectric driver circuit
• IP68 rated waterproof and dust-tight enclosure
• Wide DC voltage operational range

Applications

• Panel mount industrial control panels
• Equipment status indication
• Alarm signaling systems

Procurement Notes

Verify the specific suffix (F)D against official datasheets to confirm lead wire configuration and termination style. Ensure the required voltage matches the 5-25V DC specification. Confirm that the 70 dB SPL meets acoustic requirements for the intended installation environment. Check UL/UR approval agency listings if regulatory compliance is mandatory for the application.

Selection Notes

Select this component when a self-contained, internally driven audible indicator is required. The wide voltage tolerance allows flexibility in power supply design without external drivers. The IP68 rating makes it suitable for harsh environments where moisture or dust exposure is expected. Verify that the 2.9 kHz tone frequency is appropriate for the alert context.

Part Context

This part belongs to the AudioLarm II series of piezoelectric chimes. These devices are designed as direct replacements for older mechanical chimes in various industrial and commercial equipment. The series provides reliable visual and audible feedback through integrated internal driving electronics.

Replacement Considerations

Cross-reference dimensions and terminal types with existing installations. Verify that the replacement maintains the same IP68 sealing integrity and electrical interface specifications.
