Overview
The PS-554F-12V-VRQ is an internally driven piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a 12 VDC supply with a current draw of 200 mA. The device produces a fast pulse tone at an oscillation frequency of 2800 ± 500 Hz. Acoustic performance includes a sound pressure level ranging from 85 to 100 dBA. The unit features wire lead termination and utilizes bracket mount installation. Its physical dimensions are 54 mm x 41 mm.
Feature Summary
- Internally driven piezoelectric design for direct voltage application
- Fast pulse tone generation capability
- Bracket mount configuration for secure panel attachment
Applications
- Industrial machinery status indication
- Equipment alarm signaling
- Control panel audio alerts
Procurement Notes
Verify the specific acoustic output requirements against the 85 to 100 dBA range provided in official documentation. Confirm that the 200 mA current draw is compatible with the target power supply circuitry. Ensure the bracket mounting style aligns with the mechanical assembly constraints of the intended enclosure or panel structure.
Selection Notes
Select this component when an internally driven solution is required to simplify circuit design. The 12 VDC rating suits standard low-voltage industrial control systems. The fast pulse mode provides distinct auditory feedback compared to continuous tones. Verify that the 54 mm x 41 mm footprint fits within the available space constraints of the application housing.
Part Context
This part belongs to the PS series of industrial-grade audio indicators from Mallory Sonalert. These devices are designed for robust performance in demanding environments. The series typically offers various mounting styles and acoustic outputs to meet diverse signaling needs across automation and manufacturing sectors.
Replacement Considerations
Cross-reference with PS-554F-12V-VRQ equivalents ensuring identical 12 VDC operation, 200 mA current draw, and 2800 Hz frequency. Verify matching 54 mm x 41 mm dimensions and bracket mount compatibility before substitution.
