ZT028LAIC1R

Overview

The ZT028LAIC1R is an industrial-grade audio indicator and alarm manufactured by Mallory Sonalert. It operates on a voltage range of 20 to 28 VDC with a rated current of 25 mA. The device produces a continuous tone at a frequency of 3.9 kHz, achieving a sound pressure level of 95 dBA. It features terminal block termination and panel mount installation. The unit has an IP66 rating for environmental protection and measures 30.7 mm in diameter by 43.44 mm in height.

Feature Summary

• Combines audible alarm signaling with visual LED indication for dual-status alerting
• Provides high-intensity acoustic output suitable for noisy industrial environments
• Features robust construction with IP66 ingress protection against dust and water

Applications

• Industrial machinery status monitoring and fault indication
• Control panel integration for process alarms
• Safety systems requiring combined audio-visual warnings

Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct voltage, tone, and LED color specifications. Confirm that the terminal block interface matches the intended wiring harness or PCB layout requirements. Check for any recent updates to the datasheet regarding compliance certifications or mechanical dimensions prior to finalizing procurement orders.

Selection Notes

Select this model when a dedicated industrial alarm requires both audible and visual alerts within a compact form factor. Ensure the operating environment supports the specified DC voltage range and that the mounting space accommodates the 30.7 mm diameter and 43.44 mm height. Consider the IP66 rating if exposure to harsh conditions is expected.

Part Context

This component belongs to the ZT series of industrial alarms from Mallory Sonalert. The series is designed for demanding applications requiring reliable audio-visual signaling. The ZT028LAIC1R specifically denotes a variant with continuous tone characteristics and integrated LED functionality, distinct from pulse-tone or audio-only models within the same family.

Replacement Considerations

Consult the official Mallory Sonalert cross-reference guide for verified substitutes. Ensure replacement parts match the 20-28 VDC input, 3.9 kHz frequency, and terminal block mounting style.
