1 PRODUCT DESCRIPTION
The Liqui-tect LP3000 is a complete monitoring system that reports the presence of water and other
conductive liquids. Liqui-tect LP3000 is an advanced leak-detection controller that monitors up to
5,000ft (15243048m) of sensing cable. When a conductive liquid comes in contact with the sensing
cable:
•An audible alarm sounds.
•The distance to the leak is shown on the front-paneldisplay and via the web user interface.
•Alarm notifications may be distributed via Modbus/BACnet/SNMP/SMTP.

1.1 Supervised System
Liqui-tect LP3000 is a supervised system, which means that it continuously monitors for leaks and other
fault conditions, including a cable break and cable contamination, that trigger an alarm. When a leak or
fault is detected, a relay is activated, and LP3000 sends alarm notifications to predetermined recipients
via the configured communication method.

1.2 Distance-read Leak Detection
When the Liqui-tect LP3000 measures a current in excess of the defined leak threshold, the
microprocessor computes the distance to the leak, annunciates the leak, and logs the alarm in the event
log. The leak is communicated via the front-panel display and other configured notification methods.
1.3 Communication with Liqui-tect LP3000
A Web-based user interface (UI) provides access to system conditions and settings on-site or via network
communication.
In additon to the web-based UI, LP3000 communicates with external monitoring systems via the following
outputs:
•Modbus via EIA-485, twisted-pair wire, or TCP/IP
•BACnet/IP or BACnet/MSTP
•SNMP

ITEM DESCRIPTION
1 Test/Reset button
2 Digital LEDdisplay
3 Status LED
1.4.1 Digital LED Display
During normal operation, the digital LED displays the product name with a spinning bar ( | ) to the right of
the name.
When an alarm is present, information about the alarm condition displays. For example, if a leak is
detected, a message about the location of the leak displays as follows:
Leak detected
250 uA
at 675 ft (or 205.74m)
1.4.2 Status LED
The color of the status LEDindicates the operating state of the system.
•Green = powered-on and operating normally.
•Red = an alarm is present.
1.4.3 Test/Reset Button
The Test/Reset button runs a test cycle during normal operation and, during an alarm state, silences the
audible alarm and clears alarms.
To silence the audible alarm:
When the alarm is sounding, briefly press Test/Reset.
The audible alarm turns off, the status LED remains red, and the digital LEDcontinues to display the
alarm condition.
To clear an alarm condition:
Press and hold Test/Reset whether the alarm is sounding or not.
The alarm clears.
To test the system
During normal operation, press Test/Reset.
The LED display cycles through the following 4 lines, then returns to the default display (un-less the Re-
Alarm Interval is updated, an existing alarm may display. Refer to Leak Settings on page 23.)

2 PREPARATION
ANDINSTALLINGTHELIQUI-TECTSYSTEM
Installing the Liqui-tect system involves the following preparation before beginning:
•Choosing a readily-accessible location for the controller (wall mounted, rack mounted, under
raised floor).
•Preparing the appropriate connections for power, leak detection, and communication.
•Consulting with your ITadministrator to determine the following network settings for the
LP3000 controller:
•IP address
•Subnet mask
•Default gateway
•Creating a leak-detection cable layout diagram that considers the equipment in the area that
may be damaged by water and the possible sources of leaks. Plan the cable layout to alert
personnel when electronic equipment is threatened by a leak. An example of a layout diagram
is included in Laying the Leak-detection Cable and Securing to the Floor on page 12.
Required Equipment and Supplies:
The following is included:
•Liqui-tect LP3000 controller
•CONNECT15 connection cable
•LT500-ET end terminator
•Isolated 24 VDC power supply with interchangeable blades
•Screws and anchors for wall mounting
•Crossover cable
The following equipment is sold separately:
•Leak-detection cable(s) of chosen length, 15-ft, 35-ft, or 50-ft
•LP3000-RMB rack-mount bracket
The following tools may be field-supplied, if needed:
•Electric drill (to drive screws or drill pilot holes)
•Screw driver
•Marker/Pencil to mark screw locations
2.1 Mounting the LP3000 Controller on a Wall
1. In the location determined during preparation, mark the wall for the mounting holes using the
unit as a template.
2. If necessary, drill holes for the 4 screws that will secure the unit to the wall.
•If the wall material is not strong enough, use the supplied wall anchors.
•Clean up debris from drilling.
3. Install the 2 top screws, and hang the unit on the screws, allowing it to slip down so the screws
are in the smaller part of the pear-shaped slot.

4. Tighten the screws until snug.
5. Insert the remaining 2 screws in the bottom holes and tighten.
2.2 Mounting the LP3000 Controller in a Rack
If using the optional rack-mount bracket, LP3000-RMB, install LP3000 in the bracket as follows.
1. Place the unit in the bracket with the connectors through the opening.
2. Using the 4 nuts, secure the unit to the bracket as shown in the figure below.
