PM-100

Overview

The PM-100 is a panel-mount piezoelectric alarm manufactured by Floyd Bell Inc. It operates on a voltage range of 3 to 6 VDC and draws 10 to 60 mA. The device produces a continuous tone at a frequency of 2.9 kHz with a sound pressure level of 95 to 102 dBA. Physical dimensions are approximately 45.72 mm in diameter and 27.18 mm in height, featuring a flange for mounting and right-angle wire leads.

Feature Summary

• Internally driven piezoelectric technology for continuous tone generation
• Panel mount design with integrated flange for secure installation
• Right-angle wire leads for simplified wiring connections
• Flame retardant construction for enhanced safety

Applications

• Low-voltage industrial control panels
• Security system audible alerts
• Appliance status indicators
• Medical equipment alarms

Procurement Notes

Verify the specific datasheet version to confirm exact acoustic output levels and electrical characteristics, as specifications may vary slightly between production batches. Ensure the operating voltage aligns with the 3–6 VDC requirement. Confirm that the right-angle wire lead configuration matches the assembly layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a high-decibel audible alert is required for panel-mounted applications. The internal driver simplifies circuit design by eliminating external drive components. Consider the physical size constraints and the need for flame-retardant materials. This part is suitable for designs requiring a robust, self-contained alarm solution without complex driving electronics.

Part Context

Floyd Bell Inc specializes in piezoelectric audible alarms and smart speakers. The PM-100 belongs to their line of compact, high-output alarms designed for reliability in various electronic systems. The company holds ISO 9001 certification, indicating standardized manufacturing processes for these audible signaling devices.

Replacement Considerations

The M-100 is a PCB-mounted alternative from the same manufacturer offering similar electrical characteristics but differing in mounting style. Verify mechanical fit and lead configuration differences when substituting.
