19. When the push button a signal is sent to the branch box The signal then travels to the Master-Trol controller, which identifies the station sending the signal and automatically reviews all preprogrammed options and timing requirements If authorized, the controller returns signal activating the valve and releasing water to the fixture Master-Trol How the System Works Shown above in a Prison Comby (lav/toilet) application. Process is similar for all valves

22. Master-Trol Server Program This window could be used to display any controller on any link not communicating with the server or Clicking on a "link" above could pop up a status map of all controllers on the link.
