The probe will also send a restore (dry) report when the presence of liquid no longer detects by the flood probe for three (3) minutes. For flood reporting, the sensor requires the installation of the supplied external flood probe. The sensor is capable of detecting clean or dirty fresh water, salt water, or tap water.
