Leak Detection Monitors LDRA6

Leak Detection Monitors


The RLE Technologies LDRA6 leak detection monitor detects the presence of water, conductive fluids, and chemicals. When a leak is detected, the unit annunciates an alarm for the corresponding zone. The Model LDRA6 accommodates up to six inputs which can be configured for zone leak detection or as remote alarm annunciators. Each of the six zones can accommodate up to 1,000 ft (305m) of sensing cable or 700 ft (213m) of chemical sensing cable. As a remote alarm status panel, each of the six inputs can be configured to relay and annunciate alarms from equipment and sensors that provide a digital dry contact signal.
