Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix configuration against official Floyd Bell documentation to ensure correct terminal type and acoustic output specifications. Confirm that the required mounting hole dimensions align with the specified 35.81 mm diameter. Ensure the application voltage falls within the 5 to 25 VDC range to maintain the rated 70 dB SPL performance. Check for UL and UR approval requirements relevant to the target installation region.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a rugged, waterproof audible indicator is required for panel mounting. The IP68 rating makes it suitable for washdown or outdoor industrial settings where standard indicators would fail. Compare the 2.9 kHz tone and 70 dB output against ambient noise levels to ensure audibility. Verify that the wire lead termination style matches the existing wiring harness or connection method of the host equipment.

Alarms, Buzzers, And Sirens Part Context

This model belongs to the AudioLarm II series of piezo chimes and alarms. The series is characterized by robust construction and high sound pressure levels relative to size. Similar models in the lineup may vary in voltage ratings, mounting styles, or acoustic frequencies, but share the core piezo driver technology and durable housing materials designed for industrial reliability.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference physical dimensions and electrical parameters with alternative suppliers. Ensure any substitute part meets the same IP68 rating and UL/UR certifications. Verify compatibility with the existing control circuit driving the signal input.
