MB-09-516-W(S)

Alarms, Buzzers, And Sirens Overview

The MB-09-516-W(S) is a panel mount chime alarm manufactured by Floyd Bell Inc. It belongs to the Audiolarm II series and features an internally driven piezo driver circuit. The device operates on a DC voltage range of 5 to 25 volts with a power consumption current between 5 and 25 mA. It produces a sound pressure level of 70 dB at 5V measured from a distance of 61 cm, emitting a frequency of 2.9 kHz. The unit utilizes wire leads for termination and is designed for top port positioning. It offers IP68 protection against dust and water ingress, functioning within a temperature range of -20°C to 65°C.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix designation (W or S) during procurement, as it may indicate variations in terminal configuration or housing material. Confirm that the operating voltage aligns with the 5 to 25 VDC specification to ensure proper function. Ensure the installation environment meets the IP68 rating requirements for dust and water exposure. Check UL and UR agency approvals if required for the specific application region.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained, high-intensity audible signal is required for panel mounting. The wide voltage input range allows compatibility with various control system power supplies. The IP68 rating makes it suitable for harsh environments where standard indicators would fail. Consider the 70 dB output level relative to ambient noise levels to ensure audibility.

Alarms, Buzzers, And Sirens Part Context

This model is part of the Audiolarm II product line from Floyd Bell Inc., which specializes in industrial chimes and alarms. The series is characterized by robust construction and reliable piezo-based sound generation. It serves as a replacement or upgrade for legacy panel-mounted signaling devices requiring higher durability and environmental resistance.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other models in the Audiolarm II series for dimensional compatibility. Verify that substitute parts maintain the same voltage range and SPL output. Ensure the replacement supports the required IP68 rating if used in wet or dusty conditions.
