UB-05-515-P(F)

Overview

The UB-05-515-P(F) is a piezoelectric panel mount chime alarm manufactured by Floyd Bell Inc. It operates on a DC voltage range of 5 to 25 volts and draws between 5 and 25 mA. The device produces a sound pressure level of 70 dB at 5V measured from a distance of 61 cm. It features an internally driven indicator circuit and emits a frequency of 2.9 kHz. The unit is designed for top port mounting and offers IP68 protection against dust and water ingress. It functions within a temperature range of -20°C to 65°C and holds UL and UR approval agencies.

Feature Summary

• Piezoelectric technology for reliable acoustic output
• Internally driven driver circuit for simplified integration
• IP68 rated enclosure providing dust tight and waterproof protection
• UL and UR agency approvals for safety compliance

Applications

• Panel mounted industrial equipment alarms
• Waterproof control panel indicators
• Dust-tight machinery status signaling

Procurement Notes

Verify the specific suffix (F) matches the required lead wire configuration and termination style. Confirm that the operating voltage aligns with the 5 to 25 VDC specification to ensure proper activation. Check that the 70 dB SPL meets the environmental noise requirements for the intended installation location. Ensure the panel cutout dimensions accommodate the 35.81 mm diameter housing.

Selection Notes

Select this component when a rugged, sealed audible indicator is required for harsh environments. The IP68 rating makes it suitable for outdoor or washdown applications where standard buzzers would fail. The wide voltage input range allows flexibility in power supply design without needing external regulation for the drive signal.

Part Context

This part belongs to the AudioLarm II series of piezoelectric chimes. It is distinct from magnetic or electromagnetic buzzers due to its higher efficiency and durability. The model number indicates a 5-volt nominal operation with specific mounting and wiring characteristics defined by the manufacturer's coding system.

Replacement Considerations

Direct substitutes must match the 35.81 mm diameter, 5-25 VDC input, and IP68 sealing. Verify that any replacement maintains the 2.9 kHz frequency and 70 dB SPL to ensure equivalent audibility.
