TUHS-88Y-930-Q

Overview

The TUHS-88Y-930-Q is a panel-mount piezoelectric siren from the Twin Turbo series by Floyd Bell Inc. It features an internally driven indicator circuit and accepts DC input within a voltage range of 9 to 30 Vdc. The unit operates at a frequency of 3000±250 Hz, producing an extra loud siren tone. Its physical dimensions include a diameter of 1.300 inches (33.02mm) and a maximum seated height of 1.180 inches (29.97mm). The device is rated for operation between -20°C and 65°C and withstands 300 hours of salt spray exposure.

Feature Summary

• Internally driven indicator circuitry for simplified integration
• Extra loud siren tone generation capability
• Robust construction withstanding 300 hours of salt spray exposure

Applications

• Industrial alarm systems requiring high visibility and audibility
• Marine or coastal equipment installations due to salt spray resistance
• Panel-mounted safety warning devices in harsh environments

Procurement Notes

Verify that the operating environment temperature remains within the specified -20°C to 65°C range. Confirm that the supply voltage does not exceed the 30 Vdc maximum limit to prevent component damage. Ensure the mounting hole diameter accommodates the 33.02mm form factor. Check for RoHS compliance requirements if applicable to your assembly standards.

Selection Notes

Select this model when an extra loud siren tone is required rather than a standard buzzer sound. The internal driver simplifies design by removing the need for external oscillating circuits. Consider the 300-hour salt spray rating for corrosive environments. Verify that the 9-30 Vdc input range matches the available system power supply.

Part Context

This component belongs to the Twin Turbo series of alarms and buzzers manufactured by Floyd Bell Inc. It is designed as a direct replacement for similar panel-mount sirens requiring high decibel output. The yellow color coding aids in visual identification within control panels. It serves as a critical notification device in industrial automation and safety infrastructure.

Replacement Considerations

The TMC-86-948-Q is a comparable internally driven piezo buzzer but operates on a wider 9-48 Vdc range. The TUHS-88B-930-Q shares similar physical dimensions but may differ in acoustic output characteristics. Verify pinout compatibility and mounting hole alignment before substituting.
