CPI-2825-85PM

Alarms, Buzzers, And Sirens Overview

The CPI-2825-85PM is an internally driven piezoelectric buzzer manufactured by Same Sky. It operates at a nominal voltage of 12 VDC with a current consumption of 10 mA. The device produces a sound pressure level of 85 dB when measured at a distance of 12 inches (30 cm). Its operating frequency is centered at 3.5 kHz. The unit features a 28 mm diameter flange design intended for panel mounting applications.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric mechanism eliminates the need for external oscillators
• Flanged housing design facilitates secure panel mounting
• Compact circular form factor suitable for space-constrained enclosures

Alarms, Buzzers, And Sirens Applications

• Electronic equipment status indication
• Alarm systems requiring audible alerts
• Consumer appliance control panels

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the required sound pressure level and operating frequency align with system acoustic specifications. Confirm that the 12 VDC supply voltage matches the target circuit design. Ensure the panel cutout dimensions accommodate the 28 mm flange diameter for proper installation and sealing.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an integrated audio solution is preferred over active buzzers requiring driver circuits. The fixed 3.5 kHz tone and 85 dB output are suitable for general alerting purposes. Consider the through-hole wire lead termination method during PCB layout planning to ensure adequate clearance and mechanical stability.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the CPI series of piezoelectric indicators from Same Sky. The series offers various voltage ratings and decibel outputs. The specific suffix indicates the 12 VDC rating and 85 dB acoustic performance level within the 28 mm form factor family.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other 12V, 85dB, 3.5kHz piezo buzzers with 28mm flanges. Verify pinout compatibility and mounting hole patterns before swapping manufacturers.
