• Overview:The 508D Dual Zone Motion Sensor used an 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.

If the exterior perimeter is violated, your security system will chirp toward away the potential intruder. A violation of the interior perimeter will trigger your alarm's full siren. This type of protection is ideal for convertible vehicles.
