DESCRIPTION
The DTG is part of Linear’s Delta-3 product line and is compatible with all 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. To insure full compatibility with all gate edge safety
features, Linear recommends Miller gate edge sensors. If the edge sensor is
pressed for a minimum of 1/8 second, the DTG transmits a message to the
receiver to reverse the movement of the gate.
The DTG circuit board has been coated to prevent moisture damage and is
mounted inside a weather resistant fiberglass box. The mounting box attaches
to the gate through sealed interior mounting screws.
