TUHCH-V88Y-930-Q(S)

Overview

The TUHCH-V88Y-930-Q(S) is a panel mount chime alarm manufactured by Floyd Bell Inc, belonging to the Audiolarm II series. It features an internally driven piezo driver circuit and accepts DC input within a voltage range of 5 to 25 volts. The device operates at a frequency of 2.9 kHz with a sound pressure level of 70 dB at 5V measured at 61 cm. Power consumption ranges from 5 to 25 mA. It offers IP68 protection against dust and water ingress and is rated for operation between -20°C and 65°C. Physical dimensions include a 1.410-inch diameter and a maximum installation height of 1.480 inches, with wire leads for termination.

Feature Summary

• Internally driven piezo technology for direct DC connection
• IP68 rated enclosure providing dust tight and waterproof protection
• Panel mount design with top ported wire lead termination

Applications

• Industrial equipment status indication
• Appliance audio signaling
• Control panel audible alerts

Procurement Notes

Verify the specific suffix Q(S) against official Floyd Bell documentation to confirm exact pinout or mounting variations. Ensure the required operating voltage aligns with the 5-25V DC specification. Confirm that the 70 dB SPL meets acoustic requirements for the intended environment. Check UL/UR listing compliance if required for your region. Validate physical clearance for the 1.480-inch height constraint.

Selection Notes

Select this component when a robust, waterproof audible indicator is required for panel integration. The internal drive simplifies circuit design by eliminating external drivers. Consider the 2.9 kHz tone and 70 dB output for audibility needs. The wide voltage range supports various DC power systems. Ensure the operating temperature range suits the deployment environment.

Part Context

This part belongs to the Audiolarm II family of panel mount chimes. It shares the general form factor and piezo technology with other models in the series but differs in specific electrical ratings and acoustic output. The product line focuses on reliable, low-power audible signaling solutions for industrial and commercial applications.

Replacement Considerations

Consult official Floyd Bell substitution guides for compatible Audiolarm II replacements. Verify mechanical fit and electrical compatibility before swapping. No public substitute part numbers are confirmed.
