ZT028MDFP1R15

Overview

The ZT028MDFP1R15 is an industrial-grade audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a voltage range of 20 to 28 VDC and draws a current of 40 mA. The device produces a sound pressure level of 95 dBA at a frequency of 3.9 kHz with a fast pulse tone. It features an integrated red LED for visual indication. The unit utilizes terminal block connections and is designed for panel mounting. Its physical dimensions are approximately 30.7 mm in diameter and 43.44 mm in height, meeting IP66 ingress protection standards.

Feature Summary

• Combines audible alarm with visual red LED indication
• Fast pulse tone generation for urgent alerts
• Integrated internal driver circuitry
• High ingress protection rating for harsh environments

Applications

• Industrial machinery status monitoring
• Factory safety alarm systems
• Control panel warning indicators
• Heavy equipment operational alerts

Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct voltage, tone, and LED color specifications. Confirm terminal block type and panel cutout requirements match the installation design. Check for RoHS compliance status and relevant safety certifications such as UL or cUL before finalizing procurement orders.

Selection Notes

Select this model when both high-decibel audible warning and immediate visual confirmation are required in a single component. Ensure the operating environment supports the specified DC voltage range and that the panel mounting style fits the enclosure design. Consider the IP66 rating for suitability in dusty or wet industrial conditions where standard indicators would fail.

Part Context

This component belongs to the ZT series of industrial audio indicators from Mallory Sonalert. The series is characterized by robust construction suitable for demanding factory floor applications. These units typically integrate piezoelectric sounders with LED indicators to provide comprehensive alerting solutions without requiring external drivers.

Replacement Considerations

Consult official Mallory Sonalert cross-reference guides for verified substitutes. Ensure any replacement matches the 20-28 VDC input, 95 dBA output, and terminal block connection method. Verify dimensional compatibility for existing panel mounts.
