A brilliant Amber (High Level) and Red (Overfill) strobe lights sit on top the unit with an audible (Yodel) alarm (rated 105 D.B. at 1 meter) mounted in the front of the unit warns the tankerman of a high level/overfill condition over the entire barge(s). The 24 Volt System operates on (2) 5000 mah re-chargeable batteries with 50 hrs lifetime per charge. A Voltmeter is mounted on the face of the unit to verify voltage levels (note: a minimum of 21 volts is required for proper operation). A single/tandem switch allows the panel to be used for single or tandem loadings.
