Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific part number IP521512-1 against official DB Unlimited documentation to confirm active status and specifications. Ensure compatibility with 12 V power supplies and verify mounting hole dimensions match the 52 mm diameter requirement before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-decibel siren alert is required in a 12 V system. The active nature eliminates the need for external oscillators. Confirm that the 125 dBA output meets regulatory noise limits for the intended environment and that the flange mount fits the available enclosure space.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the DB Unlimited piezoelectric indicator series. It is designed for visual and auditory signaling applications where reliable, self-contained sound generation is necessary without complex driver circuits.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult manufacturer cross-reference lists for direct equivalents. Verify that any substitute maintains the 12 V rating, 4 kHz frequency, and 125 dBA SPL to ensure functional parity.

Alarms, Buzzers, And Sirens FAQ
