A Simplex Series alarm and pump control system for a single three-phase pump on 480V, rated 6.3 A. Suited to indoor or outdoor mounting, it pairs a control panel with an audible alarm, a red beacon and three floats.
The control panel carries an audible alarm with a silence switch, and a red beacon adds a visual warning. Three floats split the work between starting the pump, stopping it and signaling high water, each on a 20 ft (6 m) cord. A hand-off-auto (HOA) switch lets the operator run the pump manually, shut it off or leave it under float control. The system is UL and C-UL listed.
