Sensor Jam Auto Clear Procedure describes how the logic will make 3 attempts to clear a Sensor Jam if one occurs. There may be instances at specific zones or range of zones where you do not want this functionality to happen. There is a check box that allows you to disable this functionality

Clicking the Disable Sensor Jam Auto Clear check box will disable the 3 attempts to clear the Sensor Jam and will cause the zone to remain in the jam state until the sensor is cleared manually
