Liebert LT460-Z20S Module

The Liebert LT460-Z20S is a high-performance zone leak detection module designed for critical infrastructure monitoring. Engineered for seamless integration with Liebert environmental units and building management systems (BMS), this Liqui-tect 460 kit provides immediate notification of conductive fluid presence to prevent equipment damage in data centers and mechanical rooms. This specific configuration includes a 20-foot leak detection cable (LT500Y), offering a supervised solution that monitors for leaks, internal circuit faults, and power failures.

Operating on a standard 24 VAC power supply, the module features dual Form-C relay outputs (rated at 3A, 24VAC) for simultaneous signaling to local alarm panels and remote monitoring platforms. The rugged NEMA 1 enclosure houses a user-accessible circuit board with four-position DIP switches, allowing technicians to customize alarm filter delays and operational modes to eliminate nuisance trips. Designed for perimeter sensing or serpentine subfloor coverage, the LT460-Z20S ensures reliable water detection and system integrity in high-stakes HVACR environments.

Key Benefits

• Dual Contact Outputs: Features two independent Form-C dry contacts to trigger local alarms and remote BMS monitoring simultaneously.
• Supervised Circuitry: Constant monitoring of the leak detection cable ensures alerts are triggered not just for leaks, but for cable breaks or power loss.
• Customizable Sensitivity: Integrated DIP switches provide selectable reporting delays (up to 2 minutes) to prevent false alarms from temporary moisture.
• OEM Compatibility: Specifically engineered to interface with the Liebert SiteScan Web and diverse thermal management controllers.
• Compact Enclosure: The metal IP30-rated housing includes a hinged cover for rapid access to terminal blocks and configuration switches.

Common Questions

• Can I extend the cable length of this kit? No, the LT460-Z20S is a pre-packaged kit with a 20-foot cable that cannot be shortened or extended. For systems requiring up to 100 feet, the module and LT500Y sensing cables must be purchased as separate components.
• What types of fluids does the LT460-Z20S detect? It is designed to sense conductive aqueous fluids, making it ideal for monitoring chilled water piping, glycol leaks, and condensate pump overflows.
• Does the alarm reset automatically once the cable is dry? Yes, the module is non-latching; the alarm condition clears once the moisture sensing cable is wiped clean and dried.
