Overview
The SC110EPR is a piezoelectric industrial alarm from the SC series, designed for panel mounting. It operates on 30-120V AC/DC with a rated voltage of 120V and current consumption of 13 mA. The device emits a fast pulse tone at 1900 Hz with a sound pressure level of 74-85 dB. It features screw terminals for connection and measures 42.85 mm in diameter by 36 mm in height.
Feature Summary
- Piezoelectric construction for reliable audio signaling
- Integrated internal driver circuitry
- Screw terminal electrical connections
- Panel mount installation style
Applications
- Industrial control panels
- Machine status indication
- Safety alarm systems
- Process monitoring alerts
Procurement Notes
Verify the specific acoustic output rating against official Mallory Sonalert documentation, as sources indicate a range of 74-85 dB. Confirm that the 13 mA current rating aligns with the 120 VAC/120 VDC specification. Ensure the screw terminal type matches the required wiring configuration for the target application environment.
Selection Notes
Select this model for applications requiring a fast pulse audible alert within the 30-120V AC/DC operating range. The 1900 Hz frequency provides distinct auditory feedback. Consider the 42.85 mm diameter for panel cutout requirements. Verify environmental ratings if exposure to moisture or dust is expected, as IP ratings vary across the SC series.
Part Context
Part of the SC series industrial alarms, the SC110EPR utilizes piezoelectric technology for high-volume sound generation. It is designed for direct connection to standard industrial control voltages without external drivers. The unit is intended for permanent panel mounting in machinery and equipment requiring visual and audible status indicators.
Replacement Considerations
SC110DPR offers a similar form factor but operates at 2 kHz with different acoustic characteristics. SC110FPR provides a higher sound pressure level of 74-85 dB. Evaluate these alternatives based on specific frequency and volume requirements while maintaining the 30-120V AC/DC input compatibility.
