EASY-TO-INSTALL POINT LEAK DETECTION MODULES

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 auxilliary drip pans
• Overhead piping troughs
