10900077

Overview

The Werma 10900077 is an electronic audible alarm buzzer designed for continuous tone signaling. It operates on a voltage range of 115 VAC or VDC and produces a sound pressure level of 80 dB at a distance of one meter. The unit features a 2.1 kHz tone frequency and consumes 0.03 W of power. It utilizes an M22 flush-mount interface with a 22.5 mm diameter, housed in ABS/polycarbonate material.

Feature Summary

• Generates a continuous piercing tone to alert personnel in industrial environments
• Flush-mounted design compatible with standard M22 control device ranges
• Simple connection facilitated by integrated connector system

Applications

• Industrial machinery status indication
• Factory floor hazard alerts
• Control panel audible signaling

Procurement Notes

Verify the specific voltage requirement (115 VAC/VDC) against your system supply before procurement. Confirm the M22 mounting hole diameter matches your existing panel cutouts. Ensure the 80 dB output level is sufficient for the ambient noise conditions of the installation site. Check for any regional certification requirements such as CE or UKCA if applicable to your deployment location.

Selection Notes

Select this model when a compact, flush-mounted audible signal is required for M22 series installations. It is suitable for applications needing a continuous tone rather than intermittent pulsing. Consider the 80 dB acoustic output relative to background noise levels. Verify that the 115 VAC/VDC operating voltage aligns with available control circuitry. This component serves as a direct replacement for older mechanical buzzers in modern control panels.

Part Context

This component belongs to the Werma audible alarm product line, specifically engineered for integration into industrial control systems. It complements visual signaling devices by providing critical auditory feedback. The M22 form factor ensures compatibility with widely used switch and indicator standards, facilitating easy retrofitting into existing equipment architectures without major panel modifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and mounting dimensions carefully when considering generic alternatives. Ensure any replacement maintains the 115 VAC/VDC rating and M22 interface specification.
