Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix (F) against official documentation to confirm lead-free compliance or plating specifications. Confirm that the internal drive circuit matches the system's logic levels without external components. Ensure the mounting hole diameter accommodates the 35.81 mm dimension and that the enclosure meets required environmental ratings for the installation site.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained, high-volume audible indicator is required for harsh environments. The integrated driver simplifies circuit design by eliminating the need for external oscillators. Verify that the 2.9 kHz frequency is appropriate for the application's noise floor and that the 70 dB SPL is sufficient for the intended listening distance.

Alarms, Buzzers, And Sirens Part Context

This part is part of the Audiolarm II family of panel mount alarms. It shares the standard form factor and mounting characteristics common to the 09-series housing. The product line focuses on reliable, maintenance-free signaling solutions for industrial and commercial applications requiring robust environmental sealing.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other Audiolarm II models for alternative frequencies or SPL ratings. Verify mechanical compatibility with existing panel cutouts before substituting.
