UW-09-628-S(F)D

Overview

The UW-09-628-S(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 chime mechanism
• IP68 rated waterproof and dust-tight enclosure
• Wide DC voltage compatibility

Applications

• Industrial equipment status signaling
• Marine instrument alarms
• Outdoor security systems

Procurement Notes

Verify the specific suffix (F)D against official datasheets to confirm lead wire configuration and termination style. Ensure the required sound pressure level meets application needs, as output varies with voltage. Confirm UL/UR approval requirements for the target market before finalizing procurement specifications.

Selection Notes

Select this component when high environmental resistance is required due to its IP68 rating. The wide voltage range allows flexibility in power supply design without external drivers. Consider the 70 dB SPL at 5V as the baseline acoustic performance metric for audible alert applications in moderately noisy environments.

Part Context

This part belongs to the AudioLarm II series of panel mount chime alarms. It utilizes piezoelectric technology for reliable operation. The product line focuses on durable signaling devices suitable for harsh conditions. Internal driving simplifies integration into control circuits.

Replacement Considerations

Cross-reference with other AudioLarm II models for similar form factors. Verify that substitute parts maintain the same IP68 rating and internal drive capability. Check dimensional compatibility for existing panel cutouts.
