Features
WLD 2 – Quad water leak detector with WiFi and Ethernet
WLD2 is a WiFi / Ethernet water leak detector with support for WWW, SNMP and PoE. To detect
leaking liquids, it uses sensing cables. With braided liquid-absorbing cables, it is possible to
detect even the smallest volumes of liquids, such as condensation from A/C pipes or water
leaks in general – before a critical volume of water, ethylene glycol, or another conductive
liquid forms and damages become costly. In addition to flooding, the detector also detects
disconnected or damaged sensing cable for increased reliability.
Thanks to WiFi connectivity, the WLD2 WiFi water leak detector can be installed in hard-to-
access places and, in case of flooding, send an alert via e-mail, SNMP trap, or – with an external
SMS gateway by HW group – even send a text message or dial a phone number. Of course, in
critical applications, it can also communicate via wired Ethernet and can be powered with PoE.
WLD2 can be connected to the SensDesk portal using the HWg-Push protocol, as well as to
standard monitoring systems thanks to SNMP and SNMP Trap support. Flooding can be also
indicated by switching a remote output (e.g. a relay) over the network (Box-2-Box mode with
aPoseidon2 or Damocles2 unit), independently for each sensing cable.
Compared to HWg-WLD, up to 4 independent detecting cables can be connected to the WLD2
to help locate the leak more accurately.

Basic features
Basic features
• Simple installation, support for automatic network configuration via DHCP.
• Intuitive WWW interface for fast and easy installation.
• Ability to communicate over WiFi (external antenna for extended range, support for 2.4GHz,
2.11 b/g/n) and Ethernet at the same time.
• With support for up to 4 sensing cables (each max. 85m), detection capabilities can be scaled
and the source of the leak more easily identified.
• The sensing cable can be fixed using clips or adhesive tape.
• WLD2 signals the following states: OK / Flooded / Sensing cable fault.
• Flooding alerts can be send as a standard e-mail, or as a text message (SMS) through a SMS
gateway available from HW group.
• Detected leaks or WLD sensing cable disconnections can be signaled by activating a relay
output at a Poseidon2 or Damocles2 unit over the Ethernet.
• WLD2 can be easily mounted on a wall or in a 19" cabinet.
• Powered over PoE or from an external adapter.
Scalability
WLD2 supports up to 4 independent sensing cables. This makes it easier to locate the source
of the leak. Each detection circuit can consist of up to 85m of sensing cable + up to 100m of
connecting cable.
Total length max. 185 m
Sensing cable 85 m +connecting cable 100 m
50 m 10 m max. 98 m 2 m 2 m
T – Terminator
The circuit can be extended with
a2-wire connecting cable at any place.

Connectors
• Ethernet – for a wired internet connection
in case of LAN operation, or for initial
configuration in case of WiFi operation. Can
be used to power the device via PoE (Power
over Ethernet).
• WLD1 – WLD4 – for connecting up to 4 liquid
sensing cables.
• Power – connector for a 5V power supply if the
device is powered from an external adapter.
LED indicators
• Link – green LED indicates an active network
connection.
• Activity – flashing yellow LED indicates
ongoing communication over the wired
network connection.
• WiFi – blue LED indicates an active connection
to a WiFi Access Point. While establishing
the connection, flashing LED indicates status.
• WLD LED – 4 red LEDs above the connectors
for the sensing cable. When lit, the respective
circuit is in Alarm – liquid is detected or the
cable is disconnected.
Button
• Reset – to reset the device to factory defaults.
1. Turn the device off.
2. Press and hold the button.
3. Turn the device on and hold the button
for another 5 seconds.
4. All LEDs light up in sequence.
5. Turn the device on again, factory defaults

First start-up
First step
Cable connection
• Connect the device to the Ethernet (direct cable to the switch, crossed to PC).
• Connect the power adapter to the grid and connect it to the device power supply connector.
• The green LED in the Power & Mode RJ45 connector will light up.
• If connection to the Ethernet, is functional, the LINK (yellow) LED should light up shortly afterwards
and switch off during data transfer to the Ethernet (Activity signalisation).
• A quickly flashing yellow LINK LED signalises communication with the DHCP server.
