Abstract
In an automatic-faucet system, the control circuit that operates the system's valve (18) causes an indicator lamp (32) to start blinking when it first opens the valve. It keeps the lamp blinking for a predetermined duration to indicate to the user that a time interval prescribed as necessary for effective hand washing has not yet expired. When the interval does expire, the user is thereby assured that he has complied with the relevant duration regulation.
