Water Leak Detection System

The water leak system comprises of a Master Water leak detection panel (SY-3618), Distance locator Slave modules (MD-450), sensor cable (Synopsys WD-AS) and alarm sounders. The Water leak detection sensor cable typically used to detect water leaks in critical rooms to monitor leakage and to extend alarm to the BMS.

The MD-450 is locally placed in the Server rooms, and communicates with the Master Synopsys Panel through RS-485. It serves as an interface between the Master and the Sensor Cable. The Master panel SY-3618 is to be installed in the BMS room. The master panel will communicate with the clients BMS integration PC-side software using Modbus. The panel will activate a common sounder once the leak/fault is detected. The Master is equipped with a touch screen display and will display the name of the slave and the distance where the leak is been detected in meters.

Salient Features :-

• Operates on 230V 50 HZ AC
• Has potential free output and LED indication.
• Displays distance to leak location in meters.
• Indicates cable break condition.
• Maximum length of linear leak detection cable is 150meters.
• Can detect leak anywhere along the entire cable length.
• Built in audio sounder and common hooter output.
• Easy to install and operate.
• Self-restoring.
• Soft membrane switches.
• Communicates with the Master using RS485.

The water leak system comprises of a Main zone water leak panel, interface modules, sensor cable and alarm sounders. The water leak panel has potential free relay contacts which extends alarms to BMS.

The Water leak detection sensor cable typically used to detect water leaks in critical rooms to monitor leakage and optionally extend alarm in the BMS. The Cable draws excitation signal from a start of the line module. It serves as an interface between the Water leak detection panel and the Sensor Cable. The Start of Line Interface Module is locally placed in the False Flooring, and shall be connected to the WLD Panel through standard Cu- Ar Cable.

The WLD Panel is be capable of supplying power to the interface modules, and serves as the annunciation of alarms through LCD fascia. The panel activates common sounder. Testing procedure involves physical application of a wet cloth to the cable, to test the relay operation. The Panel sounds the Alarms, and optionally notifies the BMS system.

Features of Products :

• The panel equipped with LCD Display can monitor 20 Zones.
• Input to water leak cable is an isolated Ac supply which ensures the cable will not be subject to oxidation and erosion over time avoiding the degradations problems associated with DC system.
• The panel is equipped with SPDT keypad for navigation.
• Compact and elegant looks.

Water Leak Detection Conventional System (WD-AS) uses water leak cable in conjunction with Water Leak Panels to detect water under floors.

Features of Products :

• Water Leak Detection cable consists of four conductors, two water sensitive and two data.
• The cable is restorable and corrosion resistant and does not require replacement after being wet.
• Cable can be installed in the path of a potential water leak.

Installation and Testing :

• Installation: Install the WLD cable on the floor. Connect the leader end of WLD cable to WLD Panel.
• Testing: Immerse the WLD cable in water to stimulate a water leak. An alarm will be sent to WLD Panel and the display the leak distance in meters. Dry the WLD Cable to restore in normal mode.
