Product category is Directed 508D Field Disturbance Sensor Electronic
This dual zone radar sensor detects moving high-density objects using RF field-disturbance technology. Ideal for convertibles or any application where zone-intrusion protection is desired. Interfaces directly with optional 516U Vocalarm module or any Directed Electronics system offering a multiplex input for perimeter-intrusion response. Custom-chip design for outstanding stability and performance. Type: Amplifier & Processor Remotes
This is a must for any alarm system. Just the shock sensor alone won't give much protection. This way if someone is too nosy around your car it will do a few warning beeps and if they stay there the full alarm will go off.But it has to be adjusted correctly!Two things to remember when adjusting:1. It takes 20-30 seconds to fully arm and expand the radar circle. So don't just arm and step right up to the car, wait until it's fully armed and then test the sensitivity..
