INSTALLATION OVERVIEW
• The SENSOR is designed to detect iron-
based metal in motion.
• The SENSOR’s ability to detect iron-based
metal objects is based on the mass, velocity
and proximity of the object to the sensor.
EXAMPLE - A child’s bicycle moving at 2
mph @ 1’ from the sensor has a similar
effect as a car moving at 2 mph @ 6’ from
the sensor.
• The SENSOR must be stationary to function
properly.
WIRING THE WAND
1.
Obtain the instruction manual for the
gate opener.
2.
Locate the control terminals (2) that
will ONLY OPEN the gate.
3.
Verify that the above inputs when
shorted (a small wire connecting
the 2 terminals) will do all of the
following:
• OPEN the gate if the gate is idle.
• STOP and then OPEN the gate if gate is closing.
• DO NOTHING if the gate is opening.
