MW-09-948-S(F)

Alarms, Buzzers, And Sirens Overview

The MW-09-948-S(F) 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, drawing between 5 and 25 mA. It produces a sound pressure level of 70 dB at 5V measured from a distance of 61 cm. The unit has a frequency of 2.9 kHz and is rated for an operating temperature range of -20°C to 65°C. It carries UL and UR approval agencies and meets IP68 standards for dust tightness and waterproofing. The physical dimensions are 1.410 inches in diameter and 1.480 inches in maximum height, with wire leads for termination.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix (F) against the manufacturer's current datasheet to confirm terminal configuration and lead type. Ensure the required sound pressure level and voltage compatibility match the system specifications. Confirm that the IP68 rating meets the environmental exposure requirements of the installation site. Check for any recent regulatory updates regarding UL/UR certifications.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained, internally driven audible indicator is required for panel mounting. The wide voltage input range allows flexibility in power supply design. The IP68 rating makes it suitable for harsh environments where moisture or dust ingress is a concern. Compare the 70 dB SPL output against ambient noise levels to ensure audibility.

Alarms, Buzzers, And Sirens Part Context

This part is part of the Floyd Bell Audiolarm II series, which focuses on reliable piezoelectric signaling devices. The series typically offers various mounting styles and acoustic outputs. The MW-09-948-S(F) specifically addresses needs for robust, weather-resistant alarms in industrial settings.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official substitution guides for equivalent piezo chimes with similar SPL and voltage ratings. Verify mechanical fitment due to the specific 1.410-inch diameter and 1.480-inch height constraints.
