PS-552Q

Overview

The Mallory Sonalert PS-552Q is an industrial-grade piezoelectric buzzer designed for high-volume audible signaling. It operates on a nominal voltage of 12 VDC within a range of 5 to 15 VDC, drawing a current of 200 mA. The device produces a warble tone at a frequency of 2.5 kHz with a sound pressure level of 105 dB. It features wire lead termination and bracket mount installation. Physical dimensions are 54 mm in diameter and 41 mm in height.

Feature Summary

• Generates a distinct warble acoustic signal for effective alerting
• Utilizes piezoelectric technology for reliable industrial operation
• Supports bracket mounting for secure panel integration

Applications

• Industrial machinery fault warnings
• Equipment status indication
• General purpose audible alarms

Procurement Notes

Verify the specific operating voltage requirements against the 5-15 VDC range before procurement. Confirm that the 200 mA current draw is compatible with the power supply circuitry. Ensure the bracket mount style and wire lead termination match the mechanical design constraints of the target enclosure.

Selection Notes

Select this component when a high-decibel warble tone is required for critical alerts. The 12 VDC nominal rating suits standard low-voltage DC systems. Consider the physical size of 54x41 mm for panel space availability. Compare with other PS series models if different tones or voltages are needed.

Part Context

This part belongs to the PS series of industrial audio indicators from Mallory Sonalert. The series is characterized by robust construction suitable for demanding environments. The PS-552Q specifically offers a warble tone option within this lineup, distinguishing it from continuous or pulse variants.

Replacement Considerations

Consult official substitution guides for equivalent parts. Verify that any replacement maintains the same voltage, current, and acoustic output specifications.
