MC-09-201-W

Alarms, Buzzers, And Sirens Overview

The MC-09-201-W is an internally driven piezoelectric buzzer manufactured by Floyd Bell Inc. It operates within a voltage range of 30 to 120 VAC and draws a supply current between 7 and 40 mA. The device produces a sound pressure level of 95 dB at a distance of 61 cm when driven at 120 V. Its operating frequency is fixed at 2.9 kHz. This component utilizes piezo technology for acoustic signal generation.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric design eliminates the need for external oscillators
• Panel mount construction with wire leads for direct installation
• Capable of high-volume acoustic output suitable for alarm applications

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indication
• Safety alarm systems requiring audible warnings
• Control panel indicator circuits

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific AC voltage rating against your system requirements, as this model supports a wide range up to 120 VAC. Confirm that the 2.9 kHz frequency aligns with your auditory signaling standards. Ensure the panel mounting hole dimensions accommodate the physical size of the unit. Check for any environmental ratings if the application involves harsh conditions.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a self-contained, high-decibel audible indicator is required for AC-powered systems. It is suitable for applications where space constraints prevent the use of separate driver circuits. Consider the 95 dB output level to ensure audibility in noisy environments. Verify compatibility with existing panel cutouts before procurement.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Floyd Bell Inc. line of alarms, buzzers, and sirens. It is distinct from DC-operated variants like the TMC series or models with volume controls such as the MC-V09-201-S. The MC-09-201-W is specifically designed for AC mains or transformer-derived voltages, differentiating it from low-voltage DC counterparts.

Alarms, Buzzers, And Sirens Replacement Considerations

The MC-09-201-SR is a related variant but is discontinued. No direct active substitute is confirmed in public documentation. When replacing, verify that the new component matches the 30-120 VAC input range and 2.9 kHz frequency to maintain system compatibility.
