The 5050 pump control and alarm makes connecting an indoor duplex sump pump system easy! All cords are factory installed and connection is as simple as plugging in the pumps! In normal operation the pumps will alternate after each cycle. This provides equal use of both pumps - extending pump life. If an alarm condition occurs (top float switch activates), the alarm light and horn turn on. The pump in use will turn off and the other pump will turn on. Pumping will continue until the pump float switch (bottom float switch) deactivates.
NOTE: The 5050 control will only run one pump at a time.
