SCE048LA3DT8B

Alarms, Buzzers, And Sirens Overview

The SCE048LA3DT8B is an internally driven piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 28 to 48 VDC and draws a current of 40 mA. The device produces a sound pressure level of 85 dB at 28 V measured at a distance of 61 cm, with a fundamental frequency of 2.9 kHz. Designed for panel mounting, it utilizes terminal block connections for electrical interface. The unit features a slow double pulse operating mode and is certified under cUL and UL standards.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric design eliminates the need for external oscillators
• Slow double pulse acoustic output pattern for distinct alert signaling
• Terminal block connection method facilitates secure wiring integration

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indication
• Medical device alarm systems
• Control panel audible alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix DT8B against official Mallory Sonalert documentation to confirm the terminal block configuration and internal drive circuitry. Ensure the application voltage remains within the 28-48 VDC range to maintain specified performance levels. Confirm that the panel mount dimensions accommodate the physical housing requirements of the target enclosure design.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-intensity, internally driven alarm is required for industrial or medical environments. The terminal block interface suits applications where vibration resistance and secure wiring are prioritized over through-hole or wire lead options. Verify compatibility with existing control logic for the slow double pulse timing characteristics.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series of industrial-grade audio indicators from Mallory Sonalert. The series offers various acoustic patterns and mounting styles.
