About the Little Giant 1221W120H17A

The Little Giant 513289 Duplex Alarm Systems is designed to start and stop the dual pump systems in septic tanks, sewage basins, and other applications. It is recommended for use with two manual sewage, effluent, sump, or sewage pumps. It includes an audible alarm with a silence switch which sounds when a threatening liquid level condition arises. It has a red warning light that illuminates during such conditions and remains on until the condition is fixed. If a pump stops working and fails, it automatically sets off the standby pump. This Little Giant 513289 Duplex Alarm Systems is a ¾ hp device. It has a vertical mechanical float switch that comes with a 9.5’ power cord. It boasts its low-cost yet high quality performance which makes it a good alternative to conventional duplex control panels. The voltage needed to run this pump is 115V single phase. More details are available in the specification sheet. The Little Giant 513289 Duplex Alarm Systems proudly bears the UL mark and is recognized for meeting the required environmental performance standards. Little Giant and its parent company, Franklin Electric, have been making pumps for over 70 years. The quality, durability and dependability of their products have made them a world leader in pumps of virtually every variety.
