US-19-230-Q

Overview

The US-19-230-Q is a piezoelectric panel-mount siren manufactured by Floyd Bell Inc. It belongs to the Turbo series and features an internally driven indicator circuit. The device accepts DC input within a voltage range of 20 to 30 volts. It utilizes quick connect blades for electrical termination and includes screws for secure mechanical mounting. The unit produces an ultra-loud siren tone, designed for high-visibility audible alerting applications in industrial or commercial environments.

Feature Summary

• Produces an ultra-loud siren tone for effective audible warning
• Internally driven indicator circuit simplifies integration
• Panel mount design with included screws for stability
• Quick connect blade terminals facilitate rapid wiring

Applications

• Industrial machinery safety alarms
• Commercial building emergency notification systems
• Vehicle warning systems requiring loud audible alerts
• Security system sirens

Procurement Notes

Verify the specific voltage rating and tone type against the official datasheet before procurement. Confirm that the quick connect blade dimensions match existing harness connectors. Ensure the panel cutout size accommodates the 35.81mm diameter. Check for RoHS compliance status if required by project specifications. Validate that the internal drive circuit matches the control logic voltage levels.

Selection Notes

Select this model when an ultra-loud siren tone is required rather than a standard buzzer sound. The internally driven feature eliminates the need for external oscillators. Ensure the operating environment supports the specified DC voltage range. Consider the panel mount form factor for fixed installations where vibration resistance is needed. Verify terminal type compatibility with available wiring methods.

Part Context

This component is part of Floyd Bell's Turbo series of piezoelectric alarms. It shares the same physical housing and mounting style as other models in the 19-series but differs in acoustic output characteristics. The US prefix typically denotes the siren tone variant within the product line. It serves as a direct replacement for older models requiring similar mounting and electrical interfaces but with enhanced audibility.

Replacement Considerations

Direct substitutes may include other Floyd Bell models with identical mounting dimensions and voltage ranges. Verify that replacement units maintain the ultra-loud siren tone specification. Ensure terminal types and spacing are compatible with existing PCBs or wiring harnesses. Cross-reference datasheets for any changes in acoustic pressure levels or frequency response.
