AI-4228-P-SP250

Alarms, Buzzers, And Sirens Overview

The PUI Audio AI-4228-P-SP250 is an internally driven piezoelectric audio indicator designed for high-voltage AC applications. It operates within a voltage range of 60 to 250 VAC and features a rated voltage of 220 V. The device produces a continuous tone at a resonant frequency of 2.8 kHz with a sound pressure level of 94 dBA measured at 10 cm. It draws a maximum operating current of 18 mA. The unit utilizes screw terminal connections for secure wiring and supports panel mounting. It is certified under UL file number E244385, ensuring compliance with safety standards for industrial equipment.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific voltage rating requirement against the application's supply voltage, as this model is optimized for 220 VAC environments. Confirm that the mounting hole dimensions accommodate the 42.5 mm diameter housing. Ensure the installation environment allows for adequate sound propagation from the top port. Check for any specific regional certification requirements beyond the standard UL listing provided in the documentation.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained, high-decibel alarm is required for 220 VAC circuits without external drivers. Compare the 94 dBA output against lower voltage counterparts like the 12 VDC models if ambient noise levels are high. Consider the screw terminal style if vibration resistance is critical compared to quick-connect options. Evaluate the physical depth constraints against the specified height specifications before finalizing the enclosure design.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the AI series of industrial-grade audio indicators manufactured by PUI Audio. The series includes various voltage ratings and tone configurations, such as chimes and pulses. The AI-4228-P-SP250 specifically addresses the need for direct AC drive solutions, distinguishing it from low-voltage DC variants that require external oscillators or driver circuits. It shares the same form factor as other 42 mm diameter units in the lineup.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct replacements must match the 220 VAC rating and 2.8 kHz frequency. Verify that substitute parts support screw terminals and similar mounting dimensions. Note that lower voltage equivalents like the AI-4228-P-C48-R require different power supplies and are not electrically interchangeable without circuit modification.
