Operating conditions
–25°C to +85°C (–13°F to +185°F) / 5 to 90 % relative humidity
Mounting hole
1x Ø4 [mm]
Water resistance
IP67 – Sensor can be submerged in water
Dimensions / mass
36 x 50 x 22 [mm] / 80 g
Flood detector 1W-UNI 3m
Water flood sensor – spot detector, 1-Wire UNI interface.
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.

Monitoring the flood detector over LAN
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.
