ZT028LAFP1R

Overview

The ZT028LAFP1R is an industrial-grade audible and visual alarm indicator manufactured by Mallory Sonalert. It operates on a 28 VDC supply with a current draw of 40 mA. The device features a piezoelectric sounder producing a loud pulse tone at 3.9 kHz with a sound pressure level of 95 dBA. An integrated red LED provides visual indication. It utilizes terminal block connections for panel mounting and offers IP66 ingress protection against dust and water jets.

Feature Summary

• Combines high-decibel audible alerting with bright red LED visual signaling in a single unit
• Engineered for harsh environments with IP66 rated sealing against dust and water exposure
• Features internal drive circuitry for direct connection to control systems without external drivers

Applications

• Industrial machinery status monitoring and fault alarms
• Control panel integration for process safety warnings
• Heavy equipment operator alert systems

Procurement Notes

Verify the specific suffix configuration against the official Mallory Sonalert datasheet to ensure compatibility with required voltage, tone pattern, and LED color specifications. Confirm that terminal block wiring methods align with the installation environment requirements. Cross-reference the part number with the latest manufacturer documentation to validate current production status and regional availability constraints before finalizing procurement orders.

Selection Notes

Select this model when both audible and visual alerts are required simultaneously in a compact panel-mount form factor. Ensure the application environment meets the IP66 rating requirements for dust and water resistance. Verify that the 28 VDC power supply matches the system architecture and that the 40 mA current load is supported by the control circuitry. Consider the terminal block termination style for wiring convenience during assembly.

Part Context

This component belongs to the ZT series of industrial audio indicators and alarms from Mallory Sonalert. The series is designed for demanding industrial applications requiring reliable performance under various environmental conditions. The ZT series typically integrates piezoelectric transducers with electronic drivers to provide consistent output levels across operating temperatures.

Replacement Considerations

Consult the official Mallory Sonalert replacement guide for verified substitute part numbers. Direct replacements must match the 28 VDC rating, 95 dBA output, pulse tone characteristics, and IP66 sealing specifications. Verify physical dimensions and terminal block orientation to ensure mechanical compatibility.
