1.1 Description
The LD5200 is a distance-read leak detection controller. It can operate as a stand-alone device
or connect to multiple RLE leak detection controllers through its Ethernet or EIA-485 ports.
When coupled with up to 10,000 feet (3084m) of RLE’s sensing cable, it reports the presence
of water and other conductive liquids. When a conductive liquid comes in contact with the
sensing cable, the following occurs:
♦ An audible alarm sounds.
♦ The distance to the leak is shown on the LD5200’s LCD touch screen and on the LD5200’s
web interface. An integrated reference map within the web interface will also show the
location of the leak.
♦ Notification is sent via email or Modbus/SNMP/BACnet/SMTP to a central control
location, such as a building management system (BMS).
1.2 Operation
1.2.1 Supervised System
The LD5200 is a supervised system - it continually monitors sensing cable, spot detectors, and
connected leak detection controllers for continuity and produces alarms for the following
conditions:
♦ Leak detection
♦ Cable break
♦ Cable contamination
♦ Loss of communications
