SC110HR

Overview

The SC110HR is a piezoelectric industrial alarm from the Mallory Sonalert SC series. It operates on 30 to 120 VAC or VDC with a continuous tone at 4500 Hz. The unit draws 20 mA and produces an 81 dBA sound level. It features screw terminals for connection and panel mount installation. Dimensions are approximately 43 mm in diameter and 36 mm in height, weighing 45 g.

Feature Summary

• Piezoelectric technology for reliable audio signaling
• Wide voltage compatibility for AC and DC systems
• Screw terminal connections for secure mounting

Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Safety equipment monitoring

Procurement Notes

Verify the specific datasheet version for the SC110HR to confirm current manufacturing status and compliance certifications. Ensure the input power supply matches the 30-120V AC/DC rating. Confirm that the panel cutout dimensions align with the 43 mm diameter requirement for proper installation.

Selection Notes

Select this model when a continuous audible alert is required for high-voltage industrial environments. The 4500 Hz frequency provides distinct audibility. Verify that the 81 dBA output meets the ambient noise requirements of the application site without exceeding safety limits.

Part Context

This component belongs to the SC series of industrial alarms designed for harsh environments. It utilizes internal drive circuitry to simplify integration into control systems. The series is known for robust construction and consistent performance across varying temperature ranges.

Replacement Considerations

The SC110HPR offers a fast pulse tone instead of continuous operation. The SC110DJR provides a slow pulse variant. Both maintain similar voltage ratings and form factors but differ in acoustic pattern.
