2.  Determine Location for Sensor and Transmitter Module

NOTE: 

Install Transmitter Module and Sensor on the same side of the driveway as your automatic gate 

opener/receiver.

Placement of SENSOR:

•  No more than 2 ft. from edge of driveway.
•  Same side of driveway as the gate opener control box.
•  At least 25 ft. from leading edge of open gate, roadways, neighboring driveways, etc.
•  Parallel to direction of the driveway.

Placement of TRANSMITTER MODULE:

•  No more than 100 ft. from gate opener receiver.
•  Within “line of sight” of the gate opener receiver.
•  Away from lawn sprinklers (Transmitter Module is water resistant, not waterproof). 
•  Away from the driveway edge so that vehicles are unlikely to hit it.

For Optimum Performance:

•  Install the Sensor as far away as possible from power transformers, power lines, underground gas lines and 

telephone lines.

•  Locate the Sensor away from general moving traffic to prevent unwanted activation (the Sensor detects magnetic 

disturbances caused by a vehicle’s mass and velocity).

•  It is recommended that you run the Sensor Cable inside PVC conduit to prevent damage.
•  Do not run Sensor Cable in conduit with other wires such as AC power or other control wires.
•  THE SENSOR CABLE MUST NOT BE SPLICED.
