CPE-422AC

Alarms, Buzzers, And Sirens Overview

The CPE-422AC is an internally driven piezoelectric audio indicator buzzer manufactured by Same Sky. It features a flange panel mount design with wire leads for secure installation. The device operates on AC or DC voltage within a rated range of 60 to 250 VAC, specifically rated at 220 VAC. It produces a continuous single-tone sound at a frequency of 3 kHz with a sound pressure level of 92 dB measured at 220 V and 30 cm distance. The unit draws a supply current of 13 mA and has physical dimensions of 41.8 mm in diameter and 22 mm in height.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific voltage rating and acoustic performance requirements against the official datasheet before procurement. Confirm that the operating environment falls within the specified temperature limits. Ensure the mounting hole diameter matches the 41.8 mm flange dimension. Check for compliance with regional safety standards relevant to the final application. Validate lead time availability through authorized distributors as production cycles may vary.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-contained, high-decibel audio signal is required without complex driver circuitry. The wide voltage tolerance allows flexibility in power supply design. Consider the 92 dB output level for environments with moderate background noise. The wire lead termination simplifies wiring compared to solder-pin alternatives. Evaluate the 3 kHz frequency for optimal human auditory detection in critical alarm scenarios.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CPE series of piezoelectric buzzers from Same Sky, formerly CUI Devices. The series offers various sizes and mounting options for different industrial and consumer applications. The CPE-422AC represents a larger form factor designed for higher volume output and robust panel mounting needs in professional equipment.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 41.8 mm diameter, 220 VAC rating, and 92 dB SPL. Verify internal driver compatibility if replacing with similar models. Ensure the replacement maintains the same flange mounting configuration and wire lead termination type for mechanical fit.
