SC110

Overview

The SC110 is a piezoelectric buzzer and sound indicator from Mallory Sonalert Products Inc., designed for industrial applications. It operates on AC or DC input voltages ranging from 30V to 120V, with specific variants rated at 120VAC/120VDC or lower voltage ranges like 6-28V. The device features internal drive circuits and offers various acoustic outputs including continuous tones and pulse modes at frequencies such as 1.9kHz, 2kHz, 2.9kHz, and 4.5kHz. Sound pressure levels vary by model, typically between 55dBA and 95dBA. Installation is achieved via panel mount using screw terminals or quick-connect tabs, with physical dimensions generally around 43mm in diameter.

Feature Summary

• Piezoelectric technology with integrated internal driver circuitry
• Supports both AC and DC power inputs across multiple voltage ratings
• Available in continuous tone and pulse operating modes
• Panel mount construction with screw or quick-connect terminal options

Applications

• Industrial alarm systems
• Equipment status indication
• Safety warning devices
• Control panel audio alerts

Procurement Notes

Verify the specific suffix code (e.g., D, F, H, M) to confirm electrical parameters such as frequency, sound level, and mounting style. Confirm RoHS compliance status as it varies by variant. Check lead times as production cycles may range from four to thirteen weeks depending on the specific configuration and manufacturer stock availability.

Selection Notes

Select based on required voltage rating, desired acoustic pattern (continuous vs. pulse), and necessary sound pressure level. Ensure the mounting method matches the enclosure design, choosing between screw terminals or quick-connect tabs. Verify environmental certifications if used in regulated industries.

Part Context

The SC110 belongs to the SC series of industrial alarms manufactured by Mallory Sonalert. This family includes numerous variants differentiated by acoustic output, voltage compatibility, and terminal type. The series is widely recognized for rugged construction suitable for demanding industrial environments requiring reliable audio signaling.

Replacement Considerations

Direct replacements are limited due to specific parameter variations. Consider models within the same SC series with matching voltage and frequency ratings. Verify that any substitute maintains the required sound pressure level and mounting interface compatibility.
