Use these control panels in duplex systems to alternate use of the pumps with each cycle or run both simultaneously in the event of high water levels.

An Electrical Alternator is used on a duplex pump application where automatic electrical cycling of the pump is desired for added protection in residential or commercial applications. With one pump operating to handle normal flow, a second pump becomes operational in the event the water level continues to rise. The built-in alarm system, a standard feature, can be connected to sound when the second pump becomes operational (3-float switch system) or independently (4-float switch system).

All electrical systems must be installed by a qualified electrician and according to the National Electrical Code (see section 430-71 through 430-113, plus any others that apply).
