HEATED RAIN DETECTOR

The rain detector device should be placed out in the open where it can interact with the actuators in the event of continuous rain. The sensor can be connected:
• directly by wire to the KATO RADIO ADV – NRS1;
• directly by radio signal to the KATO RADIO ADV – NRS1R
• directly by wire to the K-series control units and to all the equipment which provides for processing of the signal or where a dry (potential-free) contact signal is necessary.
The sensor is not sensitive to dewdrops or humidity, dries quickly after rainfall and does not allow the formation of ice. The power supply cable is 5 m long, built to withstand the harsh outdoor environment with a highly weather-resistant PVC sheath which is also non fire-propagating and resistant to UV radiation.
