Introduction

1.0INTRODUCTION

The Liebert Liqui-tect Monitoring System is the ultimate in leak detection and retrofitting capabili- ties for computer rooms and other large areas. The Liqui-tect Monitoring System provides direct-read at the control unit location, as well as the ability to communicate with the Liebert SiteScan Web enterprise monitoring system or a building management system.

The Liqui-tect Monitoring System features an easy-to-use liquid crystal display (LCD) panel with readout of normal and alarm conditions, as well as leak location. Display and measurement modules are contained in a single compact package.

The Liqui-tect Monitoring System can monitor up to 10,000 ft. (3048m) of Liebert LT500Y leak detec- tion cable. Points along the cable may be mapped by one person, making it easy to configure within the critical space and pinpoint the location of leaks when they occur. The system determines the loca- tion of the water on the detection cable and reports the distance from the Liqui-tect panel in feet or meters. To ensure proper protection, the system continuously monitors operation, signaling system normal, leak detected and cable fault.

The Liqui-tect panel offers these and other features to protect your installation from leak damage:

•audible and visual alarms

•adjustable sensitivity setpoints for leaks and contamination

•continuous scrolling of data

•history logs

•connection to a building management system

•automatic detection of broken cables and contaminated cables

•password protection

•retention of configuration after a power failure

Two interfaces permit easy access and configuration of the Liqui-tect panel:

•LCD on the front of the enclosure

•Liebert’s SiteScan Web enterprise monitoring system through a dedicated connection port

1.1Equipment Inspection

Upon arrival of the unit, inspect all items for visible and concealed damage. Damage should be imme- diately reported to the carrier and a damage claim filed with a copy sent to Liebert or to your sales representative.
