Vehicle sensor control box (no probe) for the Hard Wired Vehicle Sensor System.

The hard wired vehicle sensor system lets you know any time a vehicle enters or leaves the driveway.

The Hard Wired Vehicle Sensor System Probe (not included) will detect vehicles moving by and send a signal through the line to the control box, which will sound a whistle.

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.
