ZT028LACTB15

Alarms, Buzzers, And Sirens Overview

The ZT028LACTB15 is a 22mm industrial alarm and sound indicator manufactured by Mallory Sonalert. It operates on a voltage range of 20-28 VAC/DC with a rated current of 40 mA. The device produces a continuous sound for 15 seconds at a frequency of 3.9 kHz. The acoustic output is rated at 85 dB when measured at 20V. It features an integrated LED light and utilizes a panel mount terminal block for installation.

Alarms, Buzzers, And Sirens Feature Summary

• Integrates audible alarm and visual LED indicator in a single unit
• Features internal driver circuitry for simplified connection
• Designed for 22mm panel mounting applications

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Factory automation control panels
• Equipment fault signaling systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage and sound characteristics. Confirm that the 22mm cutout dimension matches the enclosure design. Check RoHS compliance documentation if environmental regulations apply to the deployment site. Ensure the 40 mA current draw is supported by the power supply circuit.

Alarms, Buzzers, And Sirens Selection Notes

Select this model where combined audio and visual alerts are necessary within a standard 22mm panel opening. The 3.9 kHz frequency provides distinct audibility against background noise. The 15-second continuous operation mode suits periodic status checks rather than constant alarms. Verify that the 85 dB output level meets the ambient noise requirements of the installation environment.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the 22mm Industrial Alarms with LED Lights series from Mallory Sonalert. These devices are designed for board-level or panel-mount integration in electronic systems. The series emphasizes high-performance audible and visual warning capabilities under the Sonalert brand name, targeting industrial and commercial control applications.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official Mallory Sonalert substitution guides for compatible alternatives. Verify that any replacement maintains the 22mm form factor and 20-28 VAC/DC operating range. Ensure electrical parameters such as current draw and sound pressure level remain consistent with system requirements.
