Overview
The Floyd Bell Inc US-09-628-Q is a piezoelectric alarm siren designed for high-volume acoustic signaling. It operates within a DC voltage range of 6 to 28 volts and draws a current of 50 mA. The device produces a continuous sound level of 109 dBA at a distance of 2 feet, with an operating frequency of 2.1 kHz. It features panel mount installation and utilizes quick connect blade termination for electrical connection.
Feature Summary
- Produces ultra-loud continuous tone signaling for critical alerts
- Internally driven piezoelectric mechanism for reliable operation
- Panel mount case design with quick connect blade termination
Applications
- Industrial machinery safety alarms
- Vehicle warning systems
- Security system sirens
Procurement Notes
Verify the specific suffix designation against official datasheets to confirm exact tone characteristics and termination type. Ensure the input voltage matches the 6-28VDC specification. Confirm that the panel cutout dimensions align with the physical housing requirements for proper installation.
Selection Notes
Select this component when a high-decibel continuous alert is required in environments where visual signals are insufficient. The internally driven nature simplifies circuit design by eliminating the need for external oscillators. Verify compatibility with existing wiring harnesses due to the specific quick connect blade interface.
Part Context
This model belongs to the Floyd Bell Turbo series of piezoelectric alarms. It is part of a family of panel-mount devices designed for durability and high output. Similar models in the series may vary in voltage range or tone type, requiring careful comparison of technical specifications before substitution.
Replacement Considerations
Direct substitutes include other Floyd Bell models with identical mounting and electrical interfaces, such as the UC-09-628-Q for continuous tone variants. Verify that any replacement maintains the 109 dBA output level and 6-28VDC operating range to ensure functional equivalence.
