ZT120LAFP1R

Overview

The ZT120LAFP1R is an industrial-grade audible and visual alarm indicator manufactured by Mallory Sonalert Products Inc. It operates on a 28 VDC supply with a current draw of 40 mA. The unit features a piezoelectric buzzer producing a fast pulse tone at 3.9 kHz with a sound pressure level of 95 dBA, paired with a red LED light. Designed for panel mounting, it utilizes terminal block connections and meets IP66 ingress protection standards.

Feature Summary

• Combines high-decibel audible alarm with visual LED indication in a single compact housing
• Features internal drive circuitry for direct connection to control systems without external drivers
• Constructed with robust materials to withstand harsh industrial environments and moisture exposure

Applications

• Industrial machinery status monitoring
• Process control system alarms
• Safety interlock verification indicators

Procurement Notes

Verify the specific voltage rating matches the application circuit, as this model is designated for 28 VDC operation. Confirm that the terminal block wiring method aligns with existing panel infrastructure. Ensure the IP66 rating satisfies environmental exposure requirements for the installation site. Cross-reference the fast pulse audio pattern with system signaling protocols to avoid confusion with other alarm types.

Selection Notes

Select this component when both visual and audible alerts are required from a single point source. The 28 VDC specification limits its use to low-voltage DC control circuits. The IP66 rating makes it suitable for washdown areas or dusty environments where standard indicators would fail. Consider the physical dimensions and panel cutout requirements during the mechanical design phase.

Part Context

This part belongs to the ZT series of industrial alarms, which integrates audio and visual signals. The series is designed for heavy-duty applications requiring reliable notification in noisy or visually obstructed environments. Mallory Sonalert products are widely used in automation and manufacturing sectors for critical state indication.

Replacement Considerations

Direct replacements must match the 28 VDC input, terminal block termination, and IP66 sealing. Verify that substitute models maintain the 95 dBA output and red LED color coding to ensure consistent signaling across the system.
