Liebert Liqui-tect® Leak Detection Sensors install quickly and work
simply for reliable detection of conductive aqueous fluid leaks.

The Liqui-tect 460 Sensor provides zone protection using the easy-to­install and quick-drying Liebert leak detection cable. LEDs located on
the top cover of the module provide visual indication. A reset button
provides optional manual acknowledgement of alarms.

The top cover is hinged, allowing easy access to the electronics housed
inside the steel enclosure. Terminal blocks allow easy interconnection
of power and alarm outputs.

Dual Form-C relay outputs can simultaneously signal the local alarm
panel and remote monitoring system. The Liqui-tect 460 Sensor fea­tures supervised operation through alarms for cable faults, circuit fail­ure or loss of power, ensuring a completely self-monitored leak
detection system.

The LT460 is conveniently available in packaged kits with 20, 25, 30,
35 or 45 feet of leak detection cable and hold-down clips. Note that

additional cable cannot be added to packaged kits.

The LT460 sensor can also be purchased independently. The sensor
can accommodate up to 100 feet of leak detection cable if the sensor
and leak detection cables are purchased as independent components.
