Hard Wired Vehicle Sensor

The hard wired vehicle sensor lets you know any time a vehicle enters or leaves the driveway. The probe of the vehicle sensor detects metal objects, such as moving cars, in a ten to twelve foot radius of the sensor.

The vehicle sensor probe should be buried parallel to or under the driveway. Then the direct burial wire is run back to the control box that is located in the house. The probe will detect vehicles moving by and send a signal through the line to the control box, which will sound a whistle. The probe and wire can easily be buried in turf with a shovel or a lawn edger. If the probe is to be buried in the middle of the drive, it is best to have the probe and wire in a conduit to protect it from any damage caused by heavy vehicles. If there are gophers, moles, etc., in the area, it would be best to have the entire length of wire in a conduit.

The control box simply plugs into a 110-volt outlet, and has an on/off switch on the top of the box. There is a set of contacts to connect the two wires from the probe, as well as a set of 12-volt DC (500mA max) contacts. The voltage output can be used to operate sirens, bells, or a light timer. Everything is color coded and labeled for easy reference. The whistle and the voltage output are adjustable for 2, 4 or 8 seconds. The control box can run up to three probes, and has a sensitivity control so that it can be custom tuned to each application.
