Alarms, Buzzers, And Sirens Procurement Notes

Verify that the specific suffix (U) matches the required lead-free or halogen-free compliance standards if mandated by project specifications. Confirm that the operating voltage aligns with the 5-25V DC range to ensure proper function within the specified current limits. Ensure the mounting hole diameter accommodates the 35.81 mm body size and that the 37.59 mm height fits the available clearance.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a robust, waterproof audible indicator is required for harsh environments. The wide voltage tolerance allows flexibility in power supply design without requiring additional regulation. The high sound pressure level ensures audibility in noisy settings. Consider the physical dimensions and wire lead termination method during the mechanical layout phase to ensure compatibility with the target enclosure.

Alarms, Buzzers, And Sirens Part Context

This part is part of the Audiolarm II series, which focuses on reliable piezoelectric signaling solutions. The manufacturer specializes in audible and visual indicators for industrial and commercial applications. This specific model emphasizes environmental sealing and durability, distinguishing it from standard indoor-only chimes.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other models in the Audiolarm II series for similar form factors. Verify that any substitute maintains the IP68 rating and compatible voltage/frequency characteristics to ensure functional equivalence.
