Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix (S) against official manufacturer documentation to confirm exact terminal type or mounting variations. Ensure the required operating voltage aligns with the 5-25V DC specification. Confirm that the IP68 rating meets the environmental exposure requirements of the intended installation site. Cross-reference the UL/UR approval agency listings for compliance in regulated regions.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained, internally driven audible indicator is required for harsh environments. The wide voltage tolerance allows flexibility in power supply design. The compact cylindrical form factor facilitates integration into limited panel spaces. Verify that the 70 dB SPL output is sufficient for the ambient noise levels of the application area.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Audiolarm II family of piezo chimes designed for reliable visual and audible signaling. The series emphasizes durability through high ingress protection ratings. Components in this line are typically used where standard electronic components might fail due to moisture or particulate intrusion. The model number indicates specific physical and electrical characteristics within the broader product portfolio.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official substitution lists for equivalent piezo chimes with matching voltage and SPL requirements. Verify dimensional compatibility for panel cutouts if replacing existing units. Ensure replacement parts maintain the same IP68 certification and UL/UR approvals.
