• Supports wide DC input voltage range from 28 to 48 volts
• Utilizes screw terminals for secure electrical connection
• Designed for direct panel mounting installation

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Factory safety alarm systems
• Equipment fault warning alerts
• Process control auditory notifications

Alarms, Buzzers, And Sirens Procurement Notes

Verify the exact suffix configuration against official Mallory Sonalert documentation before ordering, as minor variations in terminal type or acoustic output may exist within the SCE series. Confirm that the 28-48VDC operating range aligns with your system power supply specifications. Ensure panel cutout dimensions accommodate the 43 mm diameter requirement for proper physical integration.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a continuous slow siren tone is required for high-noise industrial environments. The 40 mA current draw is suitable for standard control circuits. Verify that screw terminal wiring is preferred over wire leads for your specific enclosure design. Consider the 3 kHz frequency for optimal audibility in typical factory settings compared to higher pitched alarms.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of industrial audio indicators manufactured by Mallory Sonalert Products Inc. The series is characterized by robust construction for harsh environments and compliance with international safety standards including cUL certification. These devices are engineered for reliable long-term operation in critical infrastructure and heavy industrial applications requiring clear auditory warnings.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference part numbers within the SCE series for alternative voltage ratings or acoustic profiles. Verify that any substitute maintains the same 43 mm mounting diameter and screw terminal interface to ensure mechanical compatibility without modifying existing panel enclosures.
