AI-4228-P-FP250

Alarms, Buzzers, And Sirens Overview

The AI-4228-P-FP250 is an internally driven piezo buzzer transducer manufactured by PUI Audio. It operates at a rated voltage of 220 VAC with a maximum supply voltage of 250 VDC and draws a maximum operating current of 18 mA. The device produces a fast pulse tone at a resonant frequency of 2.8 kHz, generating a sound pressure level of 94 dBA measured at a distance of 100 mm. Designed for panel mounting via screw terminals, it functions within a frequency range of 2300 Hz to 3300 Hz.

• Control panel audio feedback

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct voltage rating and tone configuration. Confirm mechanical dimensions and mounting hole patterns match the target enclosure requirements. Check for RoHS compliance status if required by project specifications. Ensure input power sources align with the 220 VAC rated voltage to prevent component damage.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when high-volume acoustic output is required in industrial environments without external driver circuits. The integrated drive simplifies PCB layout compared to passive buzzers. Consider the 2.8 kHz resonant frequency for optimal audibility in noisy settings. Verify that the 18 mA current draw fits within the available power budget of the control system.

Alarms, Buzzers, And Sirens Part Context

This part belongs to PUI Audio's line of internally driven piezo buzzers designed for direct connection to AC or DC power sources. The series offers various voltage ratings and tone configurations to suit different signaling needs. The AI-4228 model specifically targets applications requiring robust, high-decibel alerts in machinery and control panels.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other PUI Audio models sharing the same form factor and electrical characteristics. Verify that substitute parts maintain the 94 dBA SPL and 2.8 kHz frequency for equivalent performance. Ensure mechanical compatibility with existing panel cutouts and mounting hardware.
