NOTE
The Sensor detects
electrical conductivity
between electrodes
1 and 3, 1 and 2 and
electrodes connect-
ed to contacts (SENS1
and SENS2).

If you want the device to be mounted on a wall or in a distance from
ooding source, sensor should be extended using an external probe
(not included).
We recommend using extension probes or cables designed to detect
water. Probes ends should be coated with non-corrosive metal.
Connection wires should not be longer than 3m with 18-26AWG
(0.14 - 0.82mm
2
). It applies also to VDC power source wires.
