HW Group 1W-UNI User manual

HW group www.HW-group.com
Water leak detection using four protruding pins on the sensor body. The
attached 3m cable can be directly connected to a RJ11 port of Ares or
Poseidon2 monitoring units.
The water sensor can be left lying on the floor (on an
electrically insulating surface), or attached to the floor
or to a wall. Designed for flood detection, senses
water and other electrically conductive liquids.
Specifications
Bus
Type
1-Wire UNI
Supported
HWg-Ares, Poseidon2, Poseidon 2250, 4002
Output states
0 = OK, 1 = flood
Connector
1x RJ11 on a 3m cable

The water flood sensor connects to the RJ11 connector for 1-Wire UNI sensors.
Flood detector does not need external power.
The flood sensor is a spot detector –detects water at a specific point (1D water detection).

Monitoring the flood detector over GSM
All three sensors are connected to the T-Box hub for 5 RJ11 sensors.
The sensors are powered from the Ares internal battery even in case of power supply failure.
Water sensor detects water at one point (on the sensor body).
1D detection indicates water detection at a single point.
The WLD sensing cable that connects to the “WLD Relay” sensor detects water leak along its
entire length.
2D detection indicates the detection of the first water drops in the entire area.
