SC110NJR

Overview

The SC110NJR is an industrial-grade piezoelectric alarm manufactured by Mallory Sonalert. It operates on a voltage rating of 30-120 VAC/120 VDC with a current draw of 24 mA. The device produces a slow pulse tone at a frequency of 2.9 kHz, achieving a sound pressure level of 98 dBA. It features screw terminals for connection and panel mount installation. The unit has an IP66 rating and measures 43 mm in diameter by 1.41 inches in height.

Feature Summary

• Piezoelectric technology for reliable audio signaling
• Slow pulse tone generation capability
• High sound pressure output for loud alerting
• IP66 rated enclosure for environmental protection

Applications

• Industrial machinery fault indication
• Control panel status monitoring
• Safety system alarm signaling
• Class I Division II hazardous area alerts

Procurement Notes

Verify the specific ordering suffix to confirm the slow pulse characteristic and voltage compatibility. Ensure the application environment meets Class I Division II requirements if utilizing this certification. Confirm panel cutout dimensions match the 43 mm diameter specification before procurement.

Selection Notes

Select this model when a distinct pulsing alert is required rather than a continuous tone. The 98 dBA output suits noisy industrial environments. Verify that the 24 mA current consumption aligns with the available power supply capacity at 120 VAC or VDC.

Part Context

This component belongs to the SCH series of industrial alarms from Mallory Sonalert. The series focuses on high-volume audible indicators designed for harsh operational conditions. It utilizes standard piezoelectric transducer technology housed in a ruggedized enclosure suitable for permanent panel integration.

Replacement Considerations

SC110N is a constant tone variant within the same series. LSC110N offers a different mounting style and higher current draw. Verify functional equivalence regarding tone pattern and electrical ratings before substitution.
