PS-531Q

Overview

The PS-531Q is an industrial piezoelectric siren from the Mallory Sonalert PS series. It operates on a DC voltage range of 5 to 15VDC with a rated voltage of 12VDC. The device produces a siren tone at a frequency of 3.5 kHz and achieves a sound pressure level of 100 dB. Electrical consumption is specified at 300 mA. Physical dimensions are 50 mm in diameter and 18 mm in height, weighing approximately 27.6 g. It utilizes wire lead termination and flange mount installation.

Feature Summary

• Generates a continuous siren audio signal for high-visibility alerting
• Constructed with piezoelectric technology for reliable operation
• Designed for direct panel or flange mounting applications

Applications

• Industrial machinery safety alarms
• Process control status indication
• Emergency warning systems

Procurement Notes

Verify the specific voltage rating and current draw requirements against the system power supply before integration. Confirm that the physical mounting hole dimensions align with the 50 mm diameter specification. Ensure the enclosure provides adequate acoustic transmission for the required decibel output. Cross-reference the terminal type with existing wiring harnesses to confirm compatibility.

Selection Notes

Select this model when a distinct siren tone is required rather than a constant beep. The 5-15VDC operating range offers flexibility for various low-voltage DC systems. Consider the 300 mA current draw for power budget calculations. The flange mount style simplifies installation compared to screw-terminal variants. Evaluate the 100 dB output against ambient noise levels to ensure audibility.

Part Context

This component belongs to the PS series of industrial audio indicators manufactured by Mallory Sonalert Products Inc. The series is characterized by robust construction suitable for demanding environments. The PS-531Q specifically addresses applications requiring a siren waveform. It represents a standard solution for audible alerts where clear differentiation from other alarm tones is necessary.
