VMD202™
Single Piece Vehicle Motion Detector
with Detachable Sensitivity Remote
Instruction Manual
The VMD202 is a compact, single-piece vehicle motion detector that operates by detecting changes in the
earth’s magnetic field that occur near the probe. It has a detection range up to 12 feet at a
minimum speed of 5 mph. The VMD202 will only detect a moving vehicle and will not detect
a stationary vehicle. It may be used as a free exit sensor to allow gates to open and guests to exit without
the use of a key fob or passcode. The VMD202 may also be wired to notify a home automation system or
security system that a vehicle is moving down a driveway. This vehicle motion detector features
a detachable sensitivity remote and is available in 50, 100, or 150 foot lead lengths.
Cautions and Warnings
The VMD202 is designed to detect moving vehicles. It is not suitable for use as a vehicle
presence detector such as a reversing loop for a gate or door.
The VMD202 detects ferrous metals. It will not detect aluminum, but will detect any
moving ferrous metallic object.
The probe must be stationary to function properly.

Controls and Indicators
Sensitivity is a function of speed and mass. The slower a vehicle is moving, the closer
it must pass the probe to trigger the detector.

IMPORTANT: EARTH GROUND CONNECTION
The VMD202 contains transient protection devices to guard the sensitive electronic circuitry from damage
and false triggering due to electrical transients caused by lightning or other sources. Always provide a good
earth ground connection to the green wire of the VMD202 remote control in standard applications or the
black wire of the VMD202 probe in solar applications. An 8’ copper rod or metal cold-water pipe provides a
sufficient earth ground connection.
