Overview
The SC110DR is a piezoelectric industrial alarm from the Mallory Sonalert SC series, designed for panel mounting. It operates on AC or DC voltages ranging from 30 to 120 VAC/DC with a current draw of 6 to 21 mA. The device emits a slow pulse tone at a frequency of 2 kHz (1900 Hz) and achieves a sound pressure level of 60 dBA at 30V measured at 61 cm. Physical dimensions include a diameter of 42.85 mm and a maximum height of 35.54 mm. It utilizes screw terminals and quick-connect tabs for electrical connections and is certified by cUL.
Feature Summary
- Features an internal driver circuit for direct connection to AC or DC power sources without external components.
- Provides audible alerts using a piezoelectric transducer technology for reliable industrial signaling.
- Includes both screw terminal and quick-connect tab options for flexible wiring integration.
Applications
- Industrial machinery status indication
- Control panel alarm signaling
- Equipment fault detection systems
Procurement Notes
Verify the specific suffix DR against official Mallory Sonalert documentation to confirm the slow pulse characteristic and voltage range. Ensure the required operating voltage aligns with the 30-120 VAC/DC specification. Confirm that the panel cutout dimensions match the 42.85 mm diameter requirement for proper installation.
Selection Notes
Select this model when a slow pulsing audible alert is required for high-voltage industrial environments. The integrated driver simplifies design by eliminating the need for external oscillators. Verify that the 60 dBA output level meets the ambient noise requirements of the intended application area.
Part Context
