UW-19-230-S(F)

Overview

The UW-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 features wire leads for connection and operates within a DC voltage range of 5 to 25 volts. It produces an audible output 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 current during operation. Physical dimensions include a diameter of 1.410 inches (35.81 mm) and a maximum installation height of 1.480 inches (37.59 mm). It is rated IP68 for dust tightness and waterproofing, with an operating temperature range of -20°C to 65°C.

Feature Summary

• Piezoelectric technology provides reliable audio signaling without external drivers.
• IP68 rating ensures protection against dust ingress and water immersion.
• Internally driven circuit simplifies integration into control panels.
• Top port location allows for direct sound projection.

Applications

• Industrial equipment status indication
• Control panel alarm systems
• Waterproof enclosure signaling

Procurement Notes

Verify the specific suffix (F) corresponds to the required lead wire configuration and termination style. Confirm that the 5-25V DC input matches the system power supply rails. Ensure the panel cutout dimensions accommodate the 1.410-inch diameter. Check environmental ratings against the installation site conditions to validate IP68 suitability.

Selection Notes

Select this component when a rugged, waterproof chime is required for panel-mounted applications. The wide voltage tolerance supports various low-voltage DC systems. Consider the 70 dB SPL for environments requiring moderate acoustic presence. Verify thermal constraints against the -20°C to 65°C operating range.

Part Context

This part belongs to the AudioLarm II series from Floyd Bell Inc, which specializes in piezoelectric signaling devices. The series offers various mounting styles and acoustic outputs. The UW-19-230-S(F) represents a standard panel-mount option with integrated driving capabilities, distinct from externally driven or battery-operated variants in the broader catalog.

Replacement Considerations

Cross-reference with other AudioLarm II models for similar form factors. Verify electrical compatibility before substituting with different series components. Ensure replacement parts maintain the same IP68 rating if environmental sealing is critical.
