The Model DTG Safety Edge Transmitter is compatible with all of Delta-3 products. In a typical installation, the DTG is mounted on a motorized gate, door or barrier arm and wired to a standard exterior safety edge sensor which presents a closed circuit across the connecting wires when an object is hit during the closing of a gate.

Ordered 4. One didn't work. Got RMA for return and exchange. Easy process. In the end, all is good. Sometimes you get a defective part, but Gatehousesupplies made it all good.
