AUM 12 automatic sensor-controlled water tap for washbasins

AUM 12 is an automatic sensor-controlled tap for washbasins with a rotary arm and a thermostat for temperature setting. Water turns on automatically when the user’s hands are within the sensor’s range and turns off when they have been removed. Water keeps on running for a short period of time after the hands have been removed from the scanning zone – after-flow delay time. The water stops flowing automatically if the sensor has been screened for longer than 120 seconds.
Tap AUM 12 is supplied with d.c. voltage of 6 V from cylindrical batteries placed under the ceramics of the washbasin. It does not need any external input of power supply. The electronics program guarantees that the electromagnetic valve does not open the water inlet without enough battery capacity to ensure its closing.
The tap is equipped with a mechanism against excess pressure of hot and cold water.
