Abstract
Abstract A monitoring and reporting system utilized to check on the condition of a water circulating and treating system by means of a private telephone line where the dialing of the number for a telephone line where the dialing of the number for a telephone set at the situs of the system and the ringing of the telephone sets a control circuit into operation. The circuit includes a timer motor rotating a series of cams for snap switches which, when closed, actuate a circuit to sense a condition of the system and provide a short interval audible signal that is picked up by the telephone receiver. One snap switch actuates a device which lifts the cradle for the telephone handset, and a series of buzzers are positioned adjacent the receiver which are connected to the condition indicators such as for conductivity, pH level, and chemical solution levels in the solution containers. The signals are controlled by the timer motor to be actuated at fixed time intervals.
