1 Product Overview
1.2. Operation
Supervised System
The LD2100 is a supervised system — it continually monitors the leak detection cable and spot
detectors for continuity. In addition to a leak triggering an alarm condition, a cable break or
excess contamination of the cable causes a cable fault indication and activates a relay. The
LD2100 sends alarm notifications to predetermined recipients when an alarm sounds. The
LD2100 produces an alarm during the following conditions:
♦ Leak detection
♦ Cable break
♦ Cable contamination
Distance-Read Leak Detection
When the LD2100's circuitry measures a current in excess of the user-defined leak threshold,
the unit's microprocessor computes the distance to the leak. The LD2100 then annunciates the
leak and logs the alarm in its event log. The summary relay has one output.
User Communication
A Web-based user interface provides information about the LD2100’s conditions. The user
interface can be used on site or remotely via network communications. The chapters and
appendices in this manual describe how to use the interface to accomplish specific
configuration and operation tasks.
The LD2100 also provides Modbus outputs via EIA-485, twisted-pair wire, or TCP/IP, as well
as BACnet/IP or BACnet/MSTP and SNMP outputs.
