UB-19-230-S(F)

Overview

The UB-19-230-S(F) 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 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 5V and 61 cm. The unit draws between 5 and 25 mA of power and features wire leads for connection. Certified by UL and UR agencies, it offers IP68 protection against dust and water ingress, functioning within an operating temperature range of -20°C to 65°C.

Feature Summary

• Piezoelectric technology providing reliable acoustic signaling
• Internally driven circuitry simplifies integration
• IP68 rated enclosure ensures waterproof and dust-tight performance
• UL and UR agency approvals for safety compliance

Applications

• Industrial control panel status indication
• Equipment fault alarms in harsh environments
• Safety warning systems requiring high ingress protection

Procurement Notes

Verify the specific suffix (F) matches the required lead configuration and termination style. Confirm that the 5-25V DC input aligns with the system power supply. Ensure the panel cutout dimensions accommodate the 35.81mm diameter housing. Check for updated certification marks if the application requires current regulatory standards.

Selection Notes

Select this model when high environmental resistance is critical due to its IP68 rating. The wide voltage tolerance allows flexibility in various DC power architectures. Consider the 70 dB SPL output for audible alerts in moderately noisy settings. Verify that the top-mounted port position suits the installation orientation.

Part Context

This component is part of the AudioLarm II family from Floyd Bell Inc, specializing in piezoelectric chimes and alarms. The series is known for robust construction and internal drive capabilities, suitable for demanding industrial applications where reliability and environmental sealing are paramount.

Replacement Considerations

Cross-reference physical dimensions and electrical parameters with existing designs. Ensure any substitute maintains the IP68 rating and UL/UR certifications. Verify compatibility with the mounting hole size and wire lead specifications.
