Liebert Liqui-Tect LT410

Provides single-point detection of leaks


Liebert LT410 point detection modules install quickly and work simply for reliable warning of potentially hazardous moisture leaks at critical points under a raised floor. A simple two-wire connection signals the alarms to a Liebert environmental unit monitor panel or at another monitoring panel.

Liebert LT point leak detection sensors provide single-point detection of leaks, using two gold-plated sensing probes. 50/60Hz, 24VAC.

Liebert LT410 has two independent outputs with the capacity to signal both a local alarm panel and a remote building management system or external equipment, such as motorized water shut-off valves.

The system may be used to detect leaks from:

•Glycol, condenser water, and chilled water cooling piping
•Humidification feed water piping
•Unit and ceiling auxiliary drip pans
•Overhead piping troughs
