LIEBERT LIQUI-TECT® 460 KITS Zone Leak Detection Module With Cable Product Specification Sheet Components Liqui-tect 460 Module Description The LT460 consists of a metal enclosure with a hinged top door providing access to the internal circuit board for wiring termination and configuration of DIP switches. The LT460 will monitor up to 100 feet of connected LT500Y leak detection cable. The Liebert Liqui-tect 460 (LT460) provides zone detection of leaks, protecting equipment by constantly monitoring the area for leaking liquids. The LT460 is the ideal solution for perimeter sensing or serpentine coverage of areas requiring up to 100 feet of cable. LT500Y Leak Detection Cable Two independent outputs provide a signal to a local alarm panel, Liebert environmental unit, remote building management system or external equipment, such as motorized water shut-off valves. The cable material and construction allow the cable to lie flat when used with hold-down clips. The LT500Y is plenum-rated and UL-listed for safe operation. • If obtained separately, cables are available in lengths of 15, 35 and 50 feet. These cables can be connected incrementally to monitor from 15 feet up to 100 feet. An end terminator and hold-down clips (two clips required for each 6-8 ft. of cable) must be ordered separately. • If obtained in a kit, cables are available in lengths of 20, 25, 30, 35 and 45 feet. Cables in kits cannot be lengthened. Hold-down clips are provided. Refer to the matrix on page 2 (Prepackaged Sizes for Liebert Units) to select a preconfigured kit sized to specific lengths for Liebert environmental units. The LT460 kit is ideally suited for the following: Configuration Switch Settings Selectable modes of operation provide flexible alarming options and protection for the cable. The LT460 constantly monitors a zone for leaks, internal faults and power failures and warns of any abnormal conditions. Top cover LEDs provide status indication and also ensure the cable is properly installed and operational under raised floors. A four-position DIP switch is used to select two alarm (filter) delays and three mutually exclusive alarm modes. The switches are located next to the wiring termination blocks.
