Abstract: The system includes a plurality of zone valves located in a gas flow pipeline. These valves contain a fiber optic bundle that is installed in the center of the valve handle. The fiber optic light comes from a source and is read by a light detector. As long as light is detected by the light detector, the circuitry within the detector will function as a closed circuit. As soon as the detector is not sensed, the detector will function as an open circuit and will provide an alarm to a floor control panel and on to a system annunciator. The system processor is capable of performing remote shunting. The operator can determine by visual reference the location of the problem. False alarms caused by intermittent faulty loops can be identified by a built in memory circuit. The circuit is also capable of detecting loss of current flow that could be caused by a number of reasons. The loss will cause an alarm condition to occur and the operator shall be notified of the system's condition.
