• Designed for direct AC line voltage operation without external drivers
• Utilizes through-hole PC pins for secure PCB integration

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indicators
• Commercial appliance alert systems
• Security panel acoustic signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version from East Electronics to confirm mechanical dimensions and electrical tolerances. Ensure the application circuit supports the 220 V rated input. Confirm that the 2.9 kHz frequency aligns with regulatory requirements for the target environment. Cross-reference the 43 mm depth against enclosure constraints before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-volume, low-cost acoustic indicator is required for mains-voltage applications. The 220 V rating eliminates the need for additional step-down transformers or driver circuits. Consider the 90 dB output level relative to ambient noise conditions. Verify that the through-hole form factor fits the existing assembly process and board layout.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the East Electronics FM series of piezoelectric buzzers. These components are typically used in simple alarm circuits where microcontroller control is unnecessary. The series offers various voltage ratings and frequencies. The FM-220A-901A specifically targets regions using 220 V AC power standards for direct connection applications.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 220 V rating, 2.9 kHz frequency, and 43 mm diameter. Check pin spacing and seated height compatibility. Verify that alternative brands offer similar SPL at the specified distance. Ensure the replacement maintains the same through-hole package type.
