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.

Linear radio controls provide a reliable communications link and fill an important need in portable wireless signaling.
However, there are some limitations which must be observed.
✶
For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as Part 15 devices. As
such, they have limited transmitter power and therefore limited range.
✶
A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio s ignals that occur
on or near their operating frequencies, regardless of code settings.
✶
Changes or modifications to the device may void FCC compliance.
✶
Infrequently used radio links should be tested regularly to protect against undet ected int erf erence or fau lt.
✶
A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor or dealer, and
these facts should be communicated to the ultimate users.
