Overview
The ZT028LACTY30 is an industrial-grade piezoelectric alarm and indicator manufactured by Mallory Sonalert. It operates on a 120 VAC supply with a current rating of 40 mA. The device produces a continuous tone at a frequency of 3.9 kHz, achieving a sound pressure level of 95 dBA. Key physical specifications include a diameter of 30.74 mm and a height of 43.5 mm. It utilizes terminal block connections for installation and is designed for panel mounting.
Feature Summary
- Integrated audible alarm and visual LED indicator in a single unit
- Capable of producing a continuous acoustic tone
- Constructed for industrial environment durability
- Features terminal block electrical connections
Applications
- Industrial machinery status indication
- Factory floor safety alarms
- Control panel audio-visual alerts
- Heavy equipment operational warnings
Procurement Notes
Verify the specific voltage requirement against the system power supply, as this model is rated for 120 VAC. Confirm that the terminal block connection type matches the existing wiring infrastructure. Ensure the panel cutout dimensions accommodate the 30.74 mm diameter and 43.5 mm height to guarantee proper fitment during installation.
Selection Notes
Select this component when both high-decibel audible warning and visible light indication are required simultaneously. It is suitable for applications needing a continuous tone rather than pulsed signals. Consider the 120 VAC input constraint and ensure the operating environment meets the industrial classification standards associated with this series.
Part Context
This part belongs to the ZT series of industrial audio indicators from Mallory Sonalert. The series is characterized by robust construction and integrated alarm functions. The ZT028LACTY30 specifically denotes the 120 VAC variant within this lineup, distinguished by its yellow LED and continuous tone output capabilities for critical alert scenarios.
Replacement Considerations
Direct substitutes within the same series may vary by voltage or tone pattern. Verify compatibility by comparing the 120 VAC rating, 95 dBA output, and terminal block interface. Cross-reference with other ZT models only if electrical and mechanical parameters align exactly.
