1.1. Description
The LD2000 is a complete monitoring system that detects and reports the presence of water
and other conductive liquids. The LD2000 couples the SeaHawk Leak Detection Cable
(sensing cable) with an advanced control panel. Each LD2000 monitors up to 2000 feet
(609m) of sensing cable. When a conductive liquid comes in contact with the sensing cable,
the distance to the leak is shown on the LD2000's front panel display. Alarm notifications are
distributed via user-configurable Modbus (EIA-485 or TCP/IP), BACnet (IP), SNMP, SMTP
(email), or Relay output.
1.2. Operation
When the LD2000's analog circuitry measures a current in excess of the user-defined leak
threshold, the unit's microprocessor computes the distance to the leak. The unit then
annunciates the leak and logs the alarm in its event log. The summary relay has one output.
The LD2000 provides a webpage interface to allow users to check updates on the unit's
conditions via the Internet or local area network. The LD2000 also provides Modbus outputs
via EIA-485, twisted-pair wire, or TCP/IP.
The LD2000 is a supervised system—it continually monitors the cable for continuity. A cable
break or excess contamination of the cable causes a cable break indication and activates a
relay. The LD2000 sends alarm notifications to predetermined recipients when an alarm
sounds. The LD2000 produces an alarm during the following conditions:
 Leak detection
 Cable break
 Cable contamination
