The Ultra Nator control and alarm system for duplex sump pump applications.

The Ultra Nator from SJE-Rhombus features two receptacles to accept two 120V pump plugs for easy pump connection. In normal operation, the pumps will alternate based on the pump switch level. If an alarm condition occurs (top float activates), the alarm indicator and horn turn on. The pump in use will turn off and the other pump will turn on. Pumping will continue until the pump switch deactivates (bottom float). This alternating action equalizes pump wear.

The Ultra Nator system is NEMA1 rated for indoor use. It features a factory-installed power cord, pump activation switch and alarm activation switch for easy installation. In addition to an audible and red visual alarm indicator, the system includes a green power on indicator and green pump run indicators (pump 1, 2). The normal/silence alarm switch is mounted externally for easy operation. The Ultra Nator system is UL/cUL listed, available with various float switch configurations, and backed by a three-year limited warranty.
