The probes call for the pump to run when they sense water and turn off when sensing oil or air. The Oil Smart® Pump Alarm is a NEMA 4X enclosure that will sound an audible alarm if the liquid level becomes too high. Simultaneously, a red beacon will illuminate as an early warning of a problem and 1 of 2 other indicator lights will illuminate. On the face of the alarm panel either a yellow light will illuminate for high oil or a white light for high water. There are dry contacts for each of these lights. The Oil Smart Alarm includes a 20′ power cord to be plugged into an 115 V outlet.
