SCE048SD3SS1B

Alarms, Buzzers, And Sirens Overview

The SCE048SD3SS1B is an internally driven piezo audio indicator from the SCE series by Mallory Sonalert. It operates on a voltage range of 28 to 48 VDC with a current rating of 40 mA. The device produces a constant tone at a frequency of 3 kHz and features a soft sound profile. It delivers a sound pressure level of 65 dB measured at 28 V and 61 cm. Designed for panel mounting, it utilizes a terminal block interface for electrical connections.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology for direct connection
• Constant tone output mode for steady state indication
• Soft acoustic profile suitable for industrial environments
• Panel mount construction with terminal block termination

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indicators
• Control panel alarm systems
• Medical device auditory alerts
• General equipment failure signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix SS1B against official Mallory Sonalert documentation to confirm the constant tone variant and terminal block configuration. Ensure input power supplies strictly adhere to the 28-48 VDC operating range to prevent component damage. Confirm that the 65 dB SPL meets the required audibility standards for the intended installation environment.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a continuous audible signal is required without external oscillation circuitry. The internal drive simplifies PCB or wiring design compared to passive buzzers. Consider the 3 kHz frequency and soft volume for applications where high-intensity noise is unnecessary or undesirable.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of electronic alarms and buzzers. The series includes variants with different voltage ratings, sound patterns, and acoustic profiles. The SCE designation indicates a standard industrial-grade piezo indicator designed for reliable performance in demanding operational conditions.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference part numbers such as SCE048SA3SS1B for AC voltage compatibility or SCE048SD3SP1B for alternative sound profiles within the same voltage class. Verify mechanical dimensions and pinout configurations before substituting to ensure physical fit and electrical correctness.
