How it works:

The alarm has a float on a line cord. On the line cord there is an adjustable weight. The weight slides on the cord and is placed in the well at the level you want the alarm to sound. The float switch is hanging below the weight. When the liquid rises to the maximum level of the float switch activates the alarm. This indicates that the liquid has reached an alarm point indicating pump failure.
