DEI 508D Dual Radar Sensor

Additional Info: Generates two invisible detection fields around your vehicle, offering either a Warn Away® response or full alarm. Great for convertibles, sunroofs, T-Tops for both trucks, SUV\'s or any size car.

The 508D uses a ultra-high frequency field to detect objects of sufficient mass which move within a defined area. The 508D triggers the first stage output if an object is detected in the outer zone of coverage, while the second stage output is triggered if the inner zone is violated.

Comes with 6.5 foot 4 wire cord with plug.
