Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version from East Electronics to confirm exact dimensional tolerances and acoustic performance curves. Ensure the 12V DC rating matches the target circuit design. Confirm that the 90dB SPL specification meets regulatory noise limits for the intended installation environment. Check for any updated compliance certifications prior to final procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a 12V DC powered audible indicator is required. The 3.7kHz frequency provides distinct audibility in moderate noise environments. The 41.2mm diameter allows for standard mounting holes. Consider the wire lead termination method if PCB mounting is not feasible. Compare against similar models like FM-12C-900L only if different acoustic or electrical parameters are needed.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the East Electronics FM series of piezoelectric buzzers. These components are generally used for simple tone generation without complex driving circuits. The FM-12C-901L variant specifically denotes the 12V rating and 90dB output level within this product line.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes may include other 12V piezoelectric buzzers with similar 90dB SPL and 3.7kHz frequency. Verify mechanical dimensions, particularly the 41.2mm diameter and mounting hole spacing, before substitution. Electrical compatibility requires matching 12V DC operation and comparable current draw.
