If this ad is still up they are still available. I have 2 Teel Model 1D002 High Water Alarms new in the box and never used. They run on 120 vac and have a separate float switch. I have no idea what they are used for. They were sold by Grainger but are discontinued. Sold for over $100. Asking $50 each. Please use the link with any questions and I will answer as quickly as I can. Thanks for checking them out.
