DESCRIPTION

The MGT is part of Linear’s Access Control product line and is the only fully supervised gate edge safety transmitter on the market today. In a typical installation, the MGT 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 supervision features, Linear recommends Miller gate edge sensors with an optional capacitor (.001 UF) installed. Please specify when ordering sensor. If the edge sensor is pressed for 1/8 second, the MGT transmits a message to the AccessMaster or AccessPro to reverse the movement of the gate. A status message is sent to the receiver once every hour which indicates battery condition and that the transmitter is operational. If the edge sensor becomes disconnected or shorted, the status transmission informs the receiver that a trouble condition exists. The MGT also features a tamper switch which will send a trouble transmission when the cover is removed.

The MGT 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.

STEP 4 Mount MGT. Choose a location as high as possible on gate in a secure position. Use the template attached to mark the location for the transmitter. You may have to attach a metal or wood plate to mount transmitter. Use a 3/32" bit and drill holes. Attach MGT to gate using the four #6 self-tapping drill point screws.

STEP 7 Set Jumper. Remove the battery protection strip. The MGT monitors the edge sensor for short circuits and cut wiring by measuring the edge sensor capacitance value. This function works with edge sensors such as Miller Edge Models MGR20 and MGS20. Some edge sensors may not present enough capacitance to pass this test. If a constant loop trouble condition is being indicated the test can be disabled by setting the Open Loop Test Option Jumper to the OFF position.

STEP 8 Test Safety Edge. Test safety edge connection by pressing the safety edge. The power light should come on.

Important!!!

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 signals 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 undetected interference or fault.

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.
