ZT120LACTR15

Overview

The ZT120LACTR15 is an industrial piezoelectric buzzer with integrated LED indicator manufactured by Mallory Sonalert Products Inc. It operates on a 90 to 120 VAC input and draws 40 mA of current. The device produces a continuous tone at a frequency of 3.7 kHz with a sound pressure level of 85 dB measured at 61 cm from the source. It features a red LED for visual signaling and utilizes terminal block connections for installation. The unit is designed for panel mounting in industrial environments.

Feature Summary

• Integrates audible alarm and visual red LED indicator
• Operates directly on high voltage AC without external drivers
• Features internal timer for 15-second continuous operation cycles

Applications

• Industrial machinery status indication
• Process control panel alarms
• Safety warning systems in manufacturing
• Equipment fault detection alerts

Procurement Notes

Verify that the specific suffix R15 corresponds to the required 15-second operational cycle duration. Confirm compatibility with existing panel cutouts and terminal block wiring configurations. Ensure the 90-120 VAC rating matches the target system voltage. Check for any regional certification requirements such as CE or UL for the intended deployment location.

Selection Notes

Select this model when a combined audio and visual alert is necessary for high-voltage AC applications. The internal timing mechanism simplifies circuit design by eliminating external control components. Consider the 85 dB output level for ambient noise conditions. Verify that the terminal block connection method suits the available wiring infrastructure.
