• Status alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'S' when ordering, as it denotes the sealed variant with the fast warble tone. Confirm that the application voltage falls within the 7 to 14 VDC range to ensure proper operation. Check official distributor availability, as stock levels may vary. Ensure the PCB layout accommodates the 23x23 mm footprint and 14 mm height constraints.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven, sealed buzzer with a distinct warble tone is required. It is suitable for applications needing 85-95 dB output within a compact 23x23 mm form factor. Consider the 7-14 VDC operating range and 50 mA current draw during circuit design. Verify compatibility with through-hole assembly processes using solder pins.

Alarms, Buzzers, And Sirens Part Context
