LP-LPD Water Leak Locating Panel

Quick Start Guide

General Note

To ensure normal operation, please follow thru various instructions listed in this manual.

The LP-LPD water leak locating panel is designed to detect liquid leak of the sensing cable up to 900m.
Once liquid leak is detected, the LP-LPD water leak locating panel gives an audible and visual alarm, also,
a 7-Segment LED will indicate the leak location and the relay output is energized. The communication
Protocol of LP-LPD water leak locating panel is Modbus RTU which is easy to interface with BMS
systems.
LP-LPD can be either stand alone or interfacing with the BMS system.
Its application includes Data Centre, Warehouse, library, museum and so on.

Product Features:

LED light shows Power, Leak, Cable Fault, and Communication Status

The LED display shows leak location and cable fault.

32 leak alarm records can be stored

Serial RS-485 communication Port with Modbus Protocol

12V DC power supply.

NO/NC Relay output is available
