Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix requirements against official Mallory Sonalert documentation before ordering. Confirm that the wire lead termination matches your assembly interface. Ensure the operating voltage remains within the 6-28 VDC range to maintain performance and longevity. Check for any recent RoHS or environmental compliance updates in the latest datasheet revision.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a continuous audible alert is required at high volume levels. The 2900 Hz frequency provides distinct audibility in noisy environments. Consider the wire lead option if screw terminals are not preferred. Verify space constraints as the unit requires a 43 mm diameter cutout for panel installation.

Alarms, Buzzers, And Sirens Part Context

Part of the SC series, established since the 1960s as a foundational component for electronic sound alarms. Mallory Sonalert manufactures these devices in Indianapolis, leveraging decades of expertise in piezoelectric audio technology. The SC series is widely recognized as a standard for industrial and medical audio indicators globally.

Alarms, Buzzers, And Sirens Replacement Considerations

SC628NLR offers identical electrical specifications but may differ in packaging or minor mechanical tolerances. SC628NDR provides a similar continuous tone but operates at a different frequency (2 kHz) and uses screw terminals instead of wire leads.
