SCE028MD3DL1B

Alarms, Buzzers, And Sirens Overview

The SCE028MD3DL1B is an industrial-grade piezoelectric audio indicator from the Mallory Sonalert SCE series. It operates on a 16-28 VDC supply with a rated voltage of 28 V and draws 40 mA. The device emits a medium volume sound at a frequency of 3 kHz. Its operational mode features a 10-second delay followed by continuous output. Designed for panel mounting, it utilizes terminal block connections for secure electrical interfacing in demanding environments.

Alarms, Buzzers, And Sirens Feature Summary

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix DL1B to confirm the 10-second delay and continuous operation mode. Ensure the power supply matches the 16-28 VDC range to prevent damage. Confirm terminal block compatibility with existing wiring harnesses. Check RoHS compliance requirements against project specifications. Validate that the medium sound level meets environmental noise criteria.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a delayed start is required for alarm sequences. Choose the SCE series for industrial durability over consumer variants. Opt for the 28 V rating if operating within the specified DC range. Consider the medium volume setting for moderate ambient noise levels. Verify panel cutout dimensions match the physical housing constraints.
