Abstract:
1. A system for detecting an actual or impending overflow condition from washroom fixtures in a washroom, comprising: a plurality of automatically actuated washroom fixtures having associated control circuitry, said automatically actuated washroom fixtures automatically actuated by detection of a patron; an overflow sensor configured with each said fixture at a location to detect an abnormal rise in water level within said fixture before water overflows said fixture; a data communications unit in wireless communication with said overflow sensors, said data communications unit configured to receive and process signals from said overflow sensors, wherein said communication with said overflow sensors is bi-directional permitting reprogramming, adjusting, or controlling operational parameters of said overflow sensors; a washroom monitoring station in communication with said data communications unit and in communication with said overflow sensors through said data communications unit, wherein said washroom monitoring station is configured for receiving and processing alerts or alarm conditions from said overflow sensors and indicating the presence of water when detected by said overflow sensors; said fixtures comprising a plurality of automatically actuated toilet and automatically actuated sink fixtures with a respective said overflow sensor associated with each of said fixtures, each said overflow sensor identified by a unique identification tag at said washroom monitoring station: said washroom monitoring station in communication with said control circuitry for said fixtures to disable said fixtures upon detection of an overflow condition; wherein said washroom includes multiple remotely actuated isolation valves with associated control circuitry in a water supply line to said fixtures, said washroom monitoring station in communication with said control circuitry for each said isolation valve, wherein upon detection of an overflow condition by an overflow sensor with unique identification tag, the isolation valve associated with the fixture with an overflow condition automatically closes.
