LIEBERT® LIQUI-TECT™ 410

POINT LEAK DETECTION SENSOR

Product Specification/Installation Guide

The Liebert® Liqui-Tect™ 410 (LT410) provides single-point detection of leaks. The point-detection sensor has two gold-plated sensing probes to prevent corrosion and to provide accurate readings. The LT410 constantly monitors for leaks, internal faults, and power failures and warns of any abnormal conditions. Mounting brackets allow for sensor height adjustment and leveling.

The LT410 is the ideal solution for sensing leaks under a raised computer floor or air conditioning drip pans.

Two independent outputs provide added flexibility with the capacity to signal both a local alarm panel, Liebert cooling unit and a remote building management system or external equipment, such as motorized water shutoff valves.

LT410 APPLICATIONS

The LT410 is ideally suited for:

• Glycol and chilled water cooling,

• Humidification supply water piping,

• Condensate pumps and drains,

• Unit and ceiling auxillary drip pans,

• Overhead piping troughs.

LOCATIONS/PLACEMENT

The LT410 is an excellent choice for:

• Large scale network control centers,

• Data centers,

• Server rooms and closets,

• Unattended, remote shelters,

• Mechanical equipment rooms,

• Sensitive areas with overhead piping,

• Industrial process control rooms.

COMPONENTS OF THE

LIQUI-TECT™ 410 MODULE

The LT410 consists of a metal enclosure with a hinged top door that provides access to the internal wiring termination. It includes side access through a box connector for installation of the power and contact wiring. The mounting brackets attach to the enclosure with adjustable slots to allow custom setting of the height of the sensing probes.
