UW-09-628-Q(S)

Overview

The UW-09-628-Q(S) is an internally driven piezoelectric alarm from Floyd Bell Inc. It operates on a DC supply voltage range of 6 to 28 volts and draws a current between 20 and 50 mA. The device produces a slow beep tone at a frequency of 2.1 kHz with a sound pressure level of 109 dB measured at 28 V. The acoustic output is rated at 109 dBA at a distance of 61 cm (2 feet).

Feature Summary

• Internally driven piezoelectric design for direct connection to power sources.
• Produces a slow beep audio warning tone.
• Ultra-loud acoustic output capability.

Applications

• Industrial equipment status indication
• Vehicle safety alarms
• Home security system sirens

Procurement Notes

Verify the specific suffix codes against official Floyd Bell documentation to confirm tone type and mounting configuration. Ensure the operating voltage matches the 6-28VDC requirement. Confirm acoustic performance specifications align with application noise environment requirements before finalizing procurement.

Selection Notes

Select this component when an internally driven, high-decibel piezoelectric alarm is required. The 6-28VDC input range allows compatibility with various standard DC power systems. Consider the 2.1kHz slow beep characteristic for distinct auditory alerts in noisy environments.

Part Context

This part belongs to the Floyd Bell Ultra Series of piezoelectric alarms. These devices are designed for robust audio warning applications requiring high volume and reliable operation across a wide voltage range without external driving circuitry.

Replacement Considerations

Cross-reference with other Floyd Bell models such as UT-09-628-Q or UC-09-628-Q for similar form factors. Verify that replacement units maintain the same internal drive capability and acoustic output levels to ensure functional equivalence.

FAQ

Is the UW-09-628-Q(S) externally or internally driven?

It is an internally driven piezoelectric buzzer, meaning it can be connected directly to a DC power source within its specified voltage range.

What is the operating voltage range for this alarm?

The device operates on a DC supply voltage ranging from 6 to 28 volts.
