ZT120LACTB

Overview

The ZT120LACTB is an internally driven piezoelectric buzzer and audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a rated voltage of 120 VAC with a current consumption of 40 mA. The device features a continuous tone at a frequency of 3.9 kHz and produces a sound pressure level of 95 dBA. It is designed for panel mounting using terminal block connections. The unit measures approximately 30.74 mm in diameter and 43.5 mm in height, incorporating a yellow LED indicator.

Feature Summary

• Integrates a piezoelectric buzzer with a visible yellow LED indicator for combined audible and visual signaling.
• Features internal driver circuitry allowing direct connection to AC power sources without external oscillators.
• Constructed with a durable housing suitable for industrial environments requiring reliable alarm indication.

Applications

• Industrial machinery status and fault alarms
• Control panel indicator systems
• Safety warning devices in manufacturing equipment

Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct voltage, tone, and LED color specifications. Confirm terminal block compatibility and panel cutout dimensions prior to integration. Cross-reference part numbers with authorized distributors to validate authenticity and current production status.

Selection Notes

Select this component when a self-contained, high-decibel alarm with visual confirmation is required for 120 VAC applications. Ensure the panel mount style and terminal block termination meet the enclosure design constraints. Compare acoustic output requirements against the 95 dBA specification to verify suitability for the intended noise environment.

Part Context

This model belongs to the ZT series of industrial-grade audio indicators from Mallory Sonalert. The series is characterized by robust construction and integrated LED options for enhanced visibility. It serves as a specialized solution for environments where standard buzzers lack sufficient audibility or require immediate visual acknowledgment of alarm states.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Generic replacements may not match the specific terminal block interface or acoustic profile. Verify that any substitute maintains the 120 VAC rating and IP compliance if environmental sealing is required.
