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.
