SC110QR

Overview

The SC110QR is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting. It operates on 30 to 120V AC only and features an internal driver circuit. The device emits a chirp tone at a frequency of 2900 Hz with a sound pressure level of 92-99 dBA. It utilizes screw terminals for connection and holds cUL approval.

Feature Summary

• Generates a chirp audio signal using piezoelectric technology
• Includes an internal driver circuit for direct voltage application
• Compatible with 30 to 120V AC power sources
• Features screw terminal connections for secure installation

Applications

• Industrial alarm systems requiring audible warnings
• Panel-mounted status indicators in control cabinets
• Safety alert devices in manufacturing environments

Procurement Notes

Verify that the application supply is strictly AC, as this model does not support DC input. Confirm the required sound pressure level range of 92-99 dBA meets environmental noise standards. Ensure the mounting hole diameter accommodates the 42.85mm housing and that screw terminal wiring matches the available torque specifications.

Selection Notes

Select this model when a chirp tone is specifically required rather than continuous or pulse sounds. It is suitable for applications needing high volume output without external drivers. Compare against SC110R if DC operation is needed, or SC110HPR for different frequency requirements within the same industrial series.

Part Context

This component belongs to the SC series of industrial alarms manufactured by Mallory Sonalert Products Inc. The series is characterized by robust piezoelectric construction and versatile mounting options. The SC110QR variant specifically addresses needs for high-decibel chirp alerts in AC-powered industrial settings.

Replacement Considerations

SC110R: Continuous tone, supports AC/DC. SC110HPR: Pulse tone, 4500Hz, supports AC/DC. SC110DJR: Slow pulse tone, 2kHz, supports AC/DC.
