Willoughby’s WMSII system takes plumbing fixture water control from inmates and puts it back in the hands of prison officials while saving time, water and money. The system is simple to install using common connectors and color-coded wiring. Water usage is reduced through fixed scheduling, dynamic usage or cycle-timing control. Facility officials have the ability to lockout toilets, sinks and showers from a central PC and detect/prevent toilet overflows. The system also provides the ability to control several different devices (two standard combination units, four toilets with overflow detection or six toilets without overflow detection).
