Low-power audio signaling systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific operating voltage requirements against the system design, as this component is rated for 1.5 VDC. Confirm that the external drive circuit can supply the required 18 mA current to achieve the specified 80 dB output. Ensure the PCB layout accommodates the 12 mm x 8.5 mm footprint and through-hole PC pin spacing for proper mechanical installation.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when low-voltage operation is critical and an external driver is available. It is distinct from self-excited buzzers, requiring an external signal source. Consider the 2.048 kHz frequency for specific auditory alert requirements. Compare dimensions and mounting style against space constraints in the target enclosure.

Alarms, Buzzers, And Sirens Part Context
