Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific voltage rating against the application's AC supply, as the component supports a wide range from 48V to 120V. Confirm that the required sound pressure level of 95dB meets the environmental noise requirements. Ensure the panel mount hole dimensions accommodate the 42.85mm diameter and that the 38.39mm height fits within the available enclosure space. Check for cUL and UL certification compliance if required by local safety regulations.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when an internally driven AC buzzer is required for industrial environments. The SCE series provides electronic volume control options via accessories like SCVC. Consider the 2.9kHz frequency for optimal audibility in noisy settings. Verify that the slow pulse mode aligns with the desired alert pattern compared to continuous or fast pulse alternatives.
