UT-09-628-S

Overview

The Floyd Bell UT-09-628-S is an ultra-loud piezoelectric alarm from the Ultra Series. It operates on a DC supply voltage range of 6 to 28 volts and draws approximately 50 mA. The device features a staccato tone output with a center frequency of 2 kHz. It achieves an acoustic output of 108 dBA measured at two feet distance. The unit utilizes flame-retardant Noryl thermoplastic construction rated UL 94V-0. It is designed for panel mounting with a diameter of 35.81 mm.

Feature Summary

• Generates high-intensity audible alarms using piezoelectric technology
• Features internally driven indicator circuitry for direct connection
• Constructed with flame-retardant Noryl thermoplastic housing
• Produces a distinct staccato tone pattern for attention-grabbing alerts

Applications

• Industrial machinery safety interlocks
• HVAC system fault indication
• Commercial appliance status signaling
• Automotive or mobile equipment warning systems

Procurement Notes

Verify the specific suffix designation against official Floyd Bell documentation to confirm electrical characteristics and mechanical dimensions. Ensure the selected variant matches the required voltage input and acoustic output specifications for the target application environment. Cross-reference part numbers carefully as minor suffix changes may alter performance parameters.

Selection Notes

Select this component when high-decibel audio warning is required in compact spaces. The 2 kHz frequency provides effective penetration in noisy environments. Verify that the 6-28 VDC operating range aligns with the available power supply. Confirm that the panel mount hole size accommodates the 35.81 mm diameter requirement.

Part Context

This model belongs to the Ultra Series of piezoelectric alarms manufactured by Floyd Bell Inc. The series is characterized by high sound pressure levels and robust construction materials. These devices are engineered for reliable operation in demanding industrial and commercial settings where clear auditory signals are critical for safety and operational awareness.

Replacement Considerations

Consult official cross-reference tools for parametrically similar parts. Ensure substitutes match the 6-28 VDC input range, 2 kHz frequency, and panel mount dimensions. Verify that alternative components offer comparable acoustic output and environmental resistance ratings.
