SCE120LA3DT8B

Alarms, Buzzers, And Sirens Overview

The SCE120LA3DT8B is an industrial-grade piezoelectric audio indicator manufactured by Mallory Sonalert. It operates on a voltage range of 30-120VAC and draws a current of 40mA. The device emits a loud sound at a frequency of 3kHz with a slow warble tone pattern. It features a 10-second delay followed by continuous operation mode. The unit utilizes terminal block connections for installation.

Alarms, Buzzers, And Sirens Feature Summary

• Incorporates internal drive circuitry for direct AC connection without external drivers
• Provides a slow warble acoustic signal for distinct auditory alerts
• Features a programmable 10-second delay before initiating continuous output
• Designed for panel mounting in industrial environments

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Factory safety alarm systems
• Process control panel notifications
• Heavy equipment operational alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the exact suffix DT8B against official Mallory Sonalert documentation to confirm the specific delay and tone configuration. Ensure the input power supply matches the 30-120VAC rating. Confirm terminal block compatibility with existing wiring harnesses. Check for RoHS compliance requirements specific to your region. Validate that the panel cutout dimensions accommodate the physical housing size.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a delayed start-up warning is required alongside a continuous alert. The 3kHz frequency offers high audibility in noisy settings. The wide voltage range allows flexibility across different industrial power standards. Consider the loudness specification if background noise levels are significant. Ensure the slow warble pattern meets regulatory or operational signaling protocols.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of electronic alarms from Mallory Sonalert. The series is characterized by robust construction suitable for harsh industrial conditions. These indicators typically integrate the driver electronics directly into the transducer assembly. This design simplifies integration into control panels compared to passive buzzers requiring separate drivers.

Alarms, Buzzers, And Sirens Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify electrical parameters such as voltage, current, and frequency against potential alternatives. Ensure mechanical dimensions and mounting styles match the existing enclosure design. Confirm that the replacement maintains the required delay and tone characteristics.
